Abstract
Heat stress (HS) induces a cellular response leading to profound changes in gene expression. Here, we show that human YTHDC1, a reader of N6-methyladenosine (m6A) RNA modification, mostly associates to the chromatin fraction and that HS induces a redistribution of YTHDC1 across the genome, including to heat-induced heat shock protein (HSP) genes. YTHDC1 binding to m6A-modified HSP transcripts co-transcriptionally promotes expression of HSPs. In parallel, hundreds of the genes enriched in YTHDC1 during HS have their transcripts undergoing YTHDC1- and m6A-dependent intron retention. Later, YTHDC1 concentrates within nuclear stress bodies (nSBs) where it binds to m6A-modified SATIII non-coding RNAs, produced in an HSF1-dependent manner upon HS. These findings reveal that YTHDC1 plays a central role in a chromatin-associated m6A-based reprogramming of gene expression during HS. Furthermore, they support the model where the subsequent and temporary sequestration of YTHDC1 within nSBs calibrates the timing of this YTHDC1-dependent gene expression reprogramming.

Abstract
Capillary electrophoresis-mass spectrometry (CE-MS) coupling is a powerful analytical solution bringing together the separation power of CE and the wealth of chemical information afforded by MS. Nevertheless, interfaces making the hyphenation of both techniques possible have always been the subject of a quest for improvement by their users in search for more sensitive and robust setups. This fact has led to numerous technical developments and new interface designs claiming to outrival existing approaches in different aspects. Nevertheless, the task of evaluating and comparing a new interface to previous solutions is not always straightforward. Issued from our own experience in the field, we herein propose a protocol to optimize the operation parameters of a new CE-MS interface design, assess its analytical performance, and compare it to a reference interface if desired. Electrospray stability, sensitivity, reproducibility, and robustness are practically evaluated as key elements of the process.

Abstract
The importance of D-amino acids in mammals associated with enantio-dependent biological functions has been increasingly highlighted. In addition to naturally occurring, D-amino acid supplementation could have a positive biological impact, including cytoprotective implications. In this context, supplementation with D-cysteine has revealed beneficial effects. Quantification of cysteine enantiomers in rodent plasma has been achieved by using 4-fluoro-7-nitrobenzofurazan derivatization of the target analytes. Cystine, the main form of cysteine in the plasma, was initially reduced to cysteine using DL-dithiothreitol. Baseline enantioseparation was then achieved in less than 3 min using a (R,R)-Whelk-O 1 stationary phase and isocratic elution using CH3OH-H2O 90:10 (v/v) with 15 mM ammonium formate (apparent pH 6.0) at 0.5 mL/min. The derivatives were then detected using negative ESI-MS in SRM mode. An external calibration was employed for D-cysteine, while L-cysteine quantification, as an endogenous analyte, was addressed using a background subtraction strategy. The method was validated. Response functions were obtained from 0 to 300 µM and from 0 to 125 µM for D-cysteine and L-cysteine, respectively. The trueness ranged from 96% to 105% for both enantiomers with repeatability and intermediate precision lower than 8% and 15% for the D-form and the endogenous L-form, respectively. The method was successfully applied for determining D- and L-cysteine in mouse plasma after D-cysteine administration.

Abstract
We investigated the scalability of a previously developed growth switch based on external control of RNA polymerase expression. Our results indicate that, in liter-scale bioreactors operating in fed-batch mode, growth-arrested Escherichia coli cells are able to convert glucose to glycerol at an increased yield. A multiomics quantification of the physiology of the cells shows that, apart from acetate production, few metabolic side effects occur. However, a number of specific responses to growth slow-down and growth arrest are launched at the transcriptional level. These notably include the downregulation of genes involved in growth-associated processes, such as amino acid and nucleotide metabolism and translation. Interestingly, the transcriptional responses are buffered at the proteome level, probably due to the strong decrease of the total mRNA concentration after the diminution of transcriptional activity and the absence of growth dilution of proteins. Growth arrest thus reduces the opportunities for dynamically adjusting the proteome composition, which poses constraints on the design of biotechnological production processes but may also avoid the initiation of deleterious stress responses.

Abstract
CE–MS is increasingly gaining momentum as an analytical tool in metabolomics, due to its ability to obtain information about the most polar elements in biological samples. This has been helped by improvements of robustness in peak identification by means of mobility‐scale representations of the electropherograms (mobilograms). As a necessary step toward facilitating the use of CE–MS for untargeted metabolomics data, the authors previously developed and introduced ROMANCE, a software automating mobilogram generation for large untargeted datasets through a simple and self‐contained user interface. Herein, we introduce a new version of ROMANCE including new features such as compatibility with other types of data (targeted MS data and 2D UV‐Vis absorption‐like electropherograms), and the much needed additional flexibility in the transformation parameters (including field ramping and the use of secondary markers), more measurement conditions (depending on detection and integration modes), and most importantly tackling the issue of quantitative peak conversion. First, we present a review of the current theoretical framework with regard to peak characterization, and we develop new formulas for multiple marker peak area corrections, for anticipating peak position precision, and for assessing peak shape distortion. Then, the new version of the software is presented and validated experimentally. We contrast the multiple marker mobility transformations with previous results, finding increased peak position precision, and finally we showcase an application to actual untargeted metabolomics data.

Abstract
The performance of an original CE-MS interface that allows the in-axis positioning of the electrospray with respect to the MS inlet was evaluated. The variations in the geometrical alignment of this configuration in the absence of a nebulizing gas afforded a significant reduction in the sheath-liquid flow rate from 3 µL/min to as low as 300 nL/min. The sheath liquid and BGE were respectively composed of H2O-iPrOHCH3COOH 50:50:1 (v/v/v) and 10% acetic acid (pH 2.2). A significant gain in sensitivity was obtained, and it was correlated to the effective mobility of the analytes. Compounds with low mobility values showed a greater sensitivity gain. Special attention was paid to the detection of proteinogenic amino acids. Linear response functions were obtained from 15 ng/mL to 500 ng/mL. The limits of quantification, as low as 34.3 ng/mL, were improved by a factor of up to six compared to the conventional configuration. The in-axis setup was ultimately applied to the absolute quantification of four important amino acids, alanine, tyrosine, methionine and valine, in standard reference material (NIST plasma). The accuracies ranged from 78 to 113%, thus demonstrating the potential of this configuration for metabolomics.

Abstract
This review describes the analytical methods that have been developed over the years to tackle the high polarity and non-chromophoric nature of amino acids (AAs). First, the historical methods are briefly presented, with a strong focus on the use of derivatization reagents to make AAs detectable with spectroscopic techniques (ultraviolet and fluorescence) and/or sufficiently retained in reversed phase liquid chromatography. Then, an overview of the current analytical strategies for achiral separation of AAs is provided, in which mass spectrometry (MS) becomes the most widely used detection mode in combination with innovative liquid chromatography or capillary electrophoresis conditions to detect AAs at very low concentration in complex matrixes. Finally, some future trends of AA analysis are provided in the last section of the review, including the use of supercritical fluid chromatography (SFC), multidimensional liquid chromatography and electrophoretic separations, hyphenation of ion exchange chromatography to mass spectrometry, and use of ion mobility spectrometry mass spectrometry (IM-MS). Various application examples will also be presented throughout the review to highlight the benefits and limitations of these different analytical approaches for AAs determination.

Abstract
Francisella tularensis is the causative agent in tularemia for which the high prevalence of treatment failure and relapse is a major concern. Directed-evolution experiments revealed that acquisition of fluoroquinolone (FQ) resistance was linked to factors in addition to mutations in DNA gyrase. Here, using F. tularensis live vaccine strain (LVS) as a model, we demonstrated that FupA/B (Fer-Utilization Protein) expression is linked to FQ susceptibility, and that the virulent strain F. tularensis subsp. tularensis SCHU S4 deleted for the homologous FupA protein exhibited even higher FQ resistance. In addition to an increased FQ minimal inhibitory concentration, LVSΔfupA/B displayed tolerance toward bactericidal compounds including ciprofloxacin and gentamicin. Interestingly, the FupA/B deletion was found to promote increased secretion of outer membrane vesicles (OMVs). Mass spectrometry-based quantitative proteomic characterization of vesicles from LVS and LVS∆fupA/B identified 801 proteins, including a subset of 23 proteins exhibiting differential abundance between both strains which may therefore contribute to the reduced antibiotic susceptibility of the FupA/B-deleted strain. We also demonstrated that OMVs are key structural elements of LVSΔfupA/B biofilms providing protection against FQ. These results provide a new basis for understanding and tackling antibiotic resistance and/or persistence of Francisella and other pathogenic members of the Thiotrichales class.

Abstract
The MHC class I antigen presentation system enables T cell immunosurveillance of cancers and viruses. A substantial fraction of the immunopeptidome derives from rapidly degraded nascent polypeptides (DRiPs). By knocking down each of the 80 ribosomal proteins, we identified proteins that modulate peptide generation without altering source protein expression. We show that 60S ribosomal proteins L6 (RPL6) and RPL28, which are adjacent on the ribosome, play opposite roles in generating an influenza A virus-encoded peptide. Depleting RPL6 decreases ubiquitin-dependent peptide presentation, whereas depleting RPL28 increases ubiquitin-dependent and -independent peptide presentation. 40S ribosomal protein S28 (RPS28) knockdown increases total peptide supply in uninfected cells by increasing DRiP synthesis from non-canonical translation of "untranslated" regions and non-AUG start codons and sensitizes tumor cells for T cell targeting. Our findings raise the possibility of modulating immunosurveillance by pharmaceutical targeting ribosomes.

Abstract
XY systems usually show chromosome-wide compensation of X-linked genes, while in many ZW systems, compensation is restricted to a minority of dosage-sensitive genes. Why such differences arose is still unclear. Here, we combine comparative genomics, transcriptomics and proteomics to obtain a complete overview of the evolution of gene dosage on the Z-chromosome of Schistosoma parasites. We compare the Z-chromosome gene content of African (Schistosoma mansoni and S. haematobium) and Asian (S. japonicum) schistosomes and describe lineage-specific evolutionary strata. We use these to assess gene expression evolution following sex-linkage. The resulting patterns suggest a reduction in expression of Z-linked genes in females, combined with upregulation of the Z in both sexes, in line with the first step of Ohno's classic model of dosage compensation evolution. Quantitative proteomics suggest that post-transcriptional mechanisms do not play a major role in balancing the expression of Z-linked genes.

Abstract
G protein-coupled receptors (GPCR) exhibit the ability to form receptor complexes that include molecularly different GPCR (ie, GPCR heteromers), which endow them with singular functional and pharmacological characteristics. The relative expression of GPCR heteromers remains a matter of intense debate. Recent studies support that adenosine A2A receptors (A2A R) and dopamine D2 receptors (D2 R) predominantly form A2A R-D2 R heteromers in the striatum. The aim of the present study was evaluating the behavioral effects of pharmacological manipulation and genetic blockade of A2A R and D2 R within the frame of such a predominant striatal heteromeric population. First, in order to avoid possible strain-related differences, a new D2 R-deficient mouse with the same genetic background (CD-1) than the A2A R knock-out mouse was generated. Locomotor activity, pre-pulse inhibition (PPI) and drug-induced catalepsy were then evaluated in wild-type, A2A R and D2 R knock-out mice, with and without the concomitant administration of either the D2 R agonist sumanirole or the A2A R antagonist SCH442416. SCH442416-mediated locomotor effects were demonstrated to be dependent on D2 R signaling. Similarly, a significant dependence on A2A R signaling was observed for PPI and for haloperidol-induced catalepsy. The results could be explained by the existence of one main population of striatal postsynaptic A2A R-D2 R heteromers, which may constitute a relevant target for the treatment of Parkinson's disease and other neuropsychiatric disorders.

Abstract
Swine influenza virus (SIV) and Mycoplasma hyopneumoniae (Mhp) are widespread in farms and are major pathogens involved in the porcine respiratory disease complex (PRDC). The aim of this experiment was to compare the pathogenicity of European avian-like swine H1N1 and European human-like reassortant swine H1N2 viruses in naïve pigs and in pigs previously infected with Mhp. Six groups of SPF pigs were inoculated intra-tracheally with either Mhp, or H1N1, or H1N2 or Mhp + H1N1 or Mhp + H1N2, both pathogens being inoculated at 21 days intervals in these two last groups. A mock-infected group was included. Although both SIV strains induced clinical signs when singly inoculated, results indicated that the H1N2 SIV was more pathogenic than the H1N1 virus, with an earlier shedding and a greater spread in lungs. Initial infection with Mhp before SIV inoculation increased flu clinical signs and pathogenesis (hyperthermia, loss of appetite, pneumonia lesions) due to the H1N1 virus but did not modify significantly outcomes of H1N2 infection. Thus, Mhp and SIV H1N1 appeared to act synergistically, whereas Mhp and SIV H1N2 would compete, as H1N2 infection led to the elimination of Mhp in lung diaphragmatic lobes. In conclusion, SIV would be a risk factor for the severity of respiratory disorders when associated with Mhp, depending on the viral subtype involved. This experimental model of coinfection with Mhp and avian-like swine H1N1 is a relevant tool for studying the pathogenesis of SIV-associated PRDC and testing intervention strategies for the control of the disease.

Abstract
Adenosine A2A receptors localized in the dorsal striatum are considered as a new target for the development of antiparkinsonian drugs. Co-administration of A2A receptor antagonists has shown a significant improvement of the effects of l-DOPA. The present review emphasizes the possible application of A2A receptor antagonists in pathological conditions other than parkinsonism, including drug addiction, sleep disorders and pain. In addition to the dorsal striatum, the ventral striatum (nucleus accumbens) contains a high density of A2A receptors, which presynaptically and postsynaptically regulate glutamatergic transmission in the cortical glutamatergic projections to the nucleus accumbens. It is currently believed that molecular adaptations of the cortico-accumbens glutamatergic synapses are involved in compulsive drug seeking and relapse. Here we review recent experimental evidence suggesting that A2A antagonists could become new therapeutic agents for drug addiction. Morphological and functional studies have identified lower levels of A2A receptors in brain areas other than the striatum, such as the ventrolateral preoptic area of the hypothalamus, where adenosine plays an important role in sleep regulation. Although initially believed to be mostly dependent on A1 receptors, here we review recent studies that demonstrate that the somnogenic effects of adenosine are largely mediated by hypothalamic A2A receptors. A2A)receptor antagonists could therefore be considered as a possible treatment for narcolepsy and other sleep-related disorders. Finally, nociception is another adenosine-regulated neural function previously thought to mostly involve A1 receptors. Although there is some conflicting literature on the effects of agonists and antagonists, which may partly be due to the lack of selectivity of available drugs, the studies in A2A receptor knockout mice suggest that A2A receptor antagonists might have some therapeutic potential in pain states, in particular where high intensity stimuli are prevalent.

Abstract
Almost all existing models for G-protein-coupled receptors (GPCRs) are based on the occurrence of monomers. Recent studies show that many GPCRs are dimers. Therefore for some receptors dimers and not monomers are the main species interacting with hormones/neurotransmitters/drugs. There are reasons for equivocal interpretations of the data fitting to receptor dimers assuming they are monomers. Fitting data using a dimer-based model gives not only the equilibrium dissociation constants for high and low affinity binding to receptor dimers but also a 'cooperativity index' that reflects the molecular communication between monomers within the dimer. The dimer cooperativity index (D(C)) is a valuable tool that enables to interpret and quantify, for instance, the effect of allosteric regulators. For different receptors heteromerization confers a specific functional property for the receptor heteromer that can be considered as a 'dimer fingerprint'. The occurrence of heteromers with different pharmacological and signalling properties opens a complete new field to search for novel drug targets useful to combat a variety of diseases and potentially with fewer side effects. Antagonists, which are quite common marketed drugs targeting GPCRs, display variable affinities when a given receptor is expressed with different heteromeric partners. This fact should be taken into account in the development of new drugs.

Abstract
Adenosine A2A receptors are highly enriched in the basal ganglia system. They are predominantly expressed in enkephalin-expressing GABAergic striatopallidal neurons and therefore are highly relevant to the function of the indirect efferent pathway of the basal ganglia system. In these GABAergic enkephalinergic neurons, the A2A receptor tightly interacts structurally and functionally with the dopamine D2 receptor. Both by forming receptor heteromers and by targeting common intracellular signaling cascades, A2A and D2 receptors exhibit reciprocal antagonistic interactions that are central to the function of the indirect pathway and hence to basal ganglia control of movement, motor learning, motivation and reward. Consequently, this A2A/D2 receptors antagonistic interaction is also central to basal ganglia dysfunction in Parkinson's disease. However, recent evidence demonstrates that, in addition to this post-synaptic site of action, striatal A2A receptors are also expressed and have physiological relevance on pre-synaptic glutamatergic terminals of the cortico-limbic-striatal and thalamo-striatal pathways, where they form heteromeric receptor complexes with adenosine A1 receptors. Therefore, A2A receptors play an important fine-tuning role, boosting the efficiency of glutamatergic information flow in the indirect pathway by exerting control, either pre- and/or post-synaptically, over other key modulators of glutamatergic synapses, including D2 receptors, group I metabotropic mGlu5 glutamate receptors and cannabinoid CB1 receptors, and by triggering the cAMP-protein kinase A signaling cascade.

Abstract
Since 1990 it has been known that dimers are the basic functional form of nearly all G-protein-coupled receptors (GPCRs) and that homo- and heterodimerization may play a key role in correct receptor maturation and trafficking to the plasma membrane. Nevertheless, homo- and heterodimerization of GPCR has become a matter of debate especially in the search for the precise physiological meaning of this phenomenon. This article focuses on how heterodimerization of adenosine A1 and A2A receptors, which are coupled to apparently opposite signalling pathways, allows adenosine to exert a fine-tuning modulation of striatal glutamatergic neurotransmission, providing a switch mechanism by which low and high concentrations of adenosine inhibit and stimulate, respectively, glutamate release.

Abstract
In 1980/81 Agnati and Fuxe introduced the concept of intramembrane receptor-receptor interactions and presented the first experimental observations for their existence in crude membrane preparations. The second step was their introduction of the receptor mosaic hypothesis of the engram in 1982. The third step was their proposal that the existence of intramembrane receptor-receptor interactions made possible the integration of synaptic (WT) and extrasynaptic (VT) signals. With the discovery of the intramembrane receptor-receptor interactions with the likely formation of receptor aggregates of multiple receptors, so called receptor mosaics, the entire decoding process becomes a branched process already at the receptor level in the surface membrane. Recent developments indicate the relevance of cooperativity in intramembrane receptor-receptor interactions namely the presence of regulated cooperativity via receptor-receptor interactions in receptor mosaics (RM) built up of the same type of receptor (homo-oligomers) or of subtypes of the same receptor (RM type1). The receptor-receptor interactions will to a large extent determine the various conformational states of the receptors and their operation will be dependent on the receptor composition (stoichiometry), the spatial organization (topography) and order of receptor activation in the RM. The biochemical and functional integrative implications of the receptor-receptor interactions are outlined and long-lived heteromeric receptor complexes with frozen RM in various nerve cell systems may play an essential role in learning, memory and retrieval processes. Intramembrane receptor-receptor interactions in the brain have given rise to novel strategies for treatment of Parkinson's disease (A2A and mGluR5 receptor antagonists), schizophrenia (A2A and mGluR5 agonists) and depression (galanin receptor antagonists). The A2A/D2, A2A/D3 and A2A/mGluR5 heteromers and heteromeric complexes with their possible participation in different types of RM are described in detail, especially in the cortico-striatal glutamate synapse and its extrasynaptic components, together with a postulated existence of A2A/D4 heteromers. Finally, the impact of intramembrane receptor-receptor interactions in molecular medicine is discussed outside the brain with focus on the endocrine, the cardiovascular and the immune systems.

Abstract
The molecular basis for the known intramembrane receptor-receptor interactions among heptahelical receptors (G protein coupled receptors, GPCR) was postulated to be heteromerization based on receptor subtype specific interactions between different types of homomers of GPCR. Adenosine and dopamine receptors in the basal ganglia have been fundamental to demonstrate the existence of receptor heteromers and the functional consequences of such molecular interactions. The heterodimer is only one type of heteromeric complex and the evidence is equally compatible with the existence of higher order heteromeric complexes, where also adapter proteins such as homer proteins and scaffolding proteins can exist, assisting in the process of linking the GPCR and ion channel receptors together in a receptor mosaic that may have special integrative value and may constitute the molecular basis for learning and memory. Heteromerization of D(2) dopamine and A(2A) adenosine receptors is reviewed by Fuxe in another article in this special issue. Here, heteromerization between D(1) dopamine and A(1) adenosine receptors is reviewed. Heteromers formed by dopamine D(1) and D(2) receptors and by adenosine A(1) and A(2A) receptors also occur in striatal cells and open new perspectives to understand why two receptors with apparently opposite effects are expressed in the same neuron and in the nerve terminals. The role of accessory proteins also capable of interacting with receptor-receptor heteromers in regulating the traffic and the molecular physiology of these receptors is also discussed. Overall, the knowledge of the reason why such complex networks of receptor-receptor and receptor-protein interactions occur in striatal cells is crucial to develop new strategies to combat neurological and neuropsychiatric diseases.

Abstract
Behavioral and microdialysis studies have been performed on antagonistic A(2A)/D(2) interactions in animal models of Parkinson's Disease. The behavioral analysis involved studies on locomotor activity in reserpinized mice, haloperidol-induced catalepsy in rats and rotational behavior in rats with unilateral 6-OHDA lesions of the ascending DA pathways (Ungerstedt model). Dual probe microdialysis studies were indirectly performed on the striatopallidal GABA neurons by studying extracellular glutamate levels in the striatum and globus pallidus of the awake freely moving rat. The striatum was perfused with A(2A) and/or D(2) agonists via reverse microdialysis. The results show that the A(2A) antagonists SCH58261 and KF17837 can increase locomotor activity in reserpinized mice and produce contralateral rotational behavior only after administration of subthreshold doses of l-DOPA or the D(2) like agonist quinpirole. Furthermore, antagonizing the A(2A) receptor (R) reduced haloperidol induced catalepsy. The behavioral results underline the view that A(2A) antagonists act by blocking A(2A) R in A(2A)/D(2) heterodimers where A(2A) R inhibits the D(2) R transduction and D(2) inhibits the adenylate cyclase (AC) activated by A(2A) R. The microdialysis studies show that the A(2A) agonist CGS21680 striatally coperfused with the D(2) agonist quinpirole more potently counteract the D(2) agonist (quinpirole) induced reduction of pallidal glutamate levels in the DA denervated vs the control striatum indicating an enhancement of the inhibitory A(2A)/D(2) interaction. In the DA denervated but not in the control striatum the A(2A) agonist CGS21680 could strongly increase striatal glutamate levels, indicating an increased receptor signaling in the A(2A) R located on the striatal glutamate terminals, where also D(2) like R exist, here probably as D(4). Thus, the signaling of this A(2A) R may be set free by the loss of D(4) tone on the AC activated by A(2A) in this postulated A(2A)/D(4) heteromer on the glutamate terminals. Taken together, the results indicate that the antiparkinsonian actions of A(2A) antagonists probably are produced by blockade of A(2A) R in the A(2A)/D(2) heterodimers mainly located in the striatopallidal GABA neurons.

Abstract
The present paper enlightens a new point of view on brain homeostasis and communication, namely how the brain takes advantage of different chemical-physical phenomena such as pressure waves, and temperature and concentration gradients to allow the renewal of the extra-cellular fluid (i.e., the homeostasis of the brain internal milieu) as well as some forms of intercellular communications (Volume Transmission) at an energy cost much lower than the classical synaptic transmission (the prototype of Wiring Transmission). In particular, the possible functional meaning of the intracranial pressure waves is discussed in the frame of the so called "tide hypothesis" which maintains that the pressure waves, created by the cardiac pump, modulate the cerebro-spinal fluid flow from and towards the subarachnoid space as well as towards and from the Virchow-Robin spaces. These fluid push-pull movements favor both the migration of signals and the extra-cellular fluid renewal, especially in the cerebral cortex.

Abstract
Homocysteine (HC) may work inter alia as a Volume Transmission signal since HC is present in the brain and cerebrospinal fluid and binds to NMDA receptors. Furthermore, in cell cultures increased HC formation increases its export. In the present study we have shown that after intravenous injection in intact animals HC penetrates the blood-brain barrier. Hence, it works as a blood-born humoral signal. Furthermore, we have studied HC plasma levels in a group of Alzheimer's (AD) patients and compared with a group of age-matched patients. It has been confirmed that a positive correlation exists between age and HC plasma levels in the control group, but not in the AD patients. These results may depend on the fact that in AD patients high HC plasma levels (possibly associated with high glycine levels and/or excessive glutamate release) have favored neurodegeneration and, once this pathological process has been triggered off, the plasma HC levels become independent of the "physiological" aging-induced increase of HC plasma levels.

Abstract
Recently evidence has been presented that adenosine A2A and dopamine D2 receptors form functional heteromeric receptor complexes as demonstrated in human neuroblastoma cells and mouse fibroblast Ltk- cells. These A2A/D2 heteromeric receptor complexes undergo coaggregation, cointernalization, and codesensitization on D2 or A2A receptor agonist treatments and especially after combined agonist treatment. It is hypothesized that the A2A/D2 receptor heteromer represents the molecular basis for the antagonistic A2A/D2 receptor interactions demonstrated at the biochemical and behavioral levels. Functional heteromeric complexes between A2A and metabotropic glutamate 5 receptors (mGluR5) have also recently been demonstrated in HEK-293 cells and rat striatal membrane preparations. The A2A/mGluR5 receptor heteromer may account for the synergism found after combined agonist treatments demonstrated in different in vitro and in vivo models. D2, A2A, and mGluR5 receptors are found together in the dendritic spines of the striatopallidal GABA neurons. Therefore, possible D2/A2A/mGluR5 multimeric receptor complexes and the receptor interactions within them may have a major role in controlling the dorsal and ventral striatopallidal GABA neurons involved in Parkinson's disease and in schizophrenia and drug addiction, respectively.

Abstract
Learning in neuronal networks occurs by instructions to the neurons to change their synaptic weights (i.e., efficacies). According to the present model a molecular mechanism that can contribute to change synaptic weights may be represented by multiple interactions between membrane receptors forming aggregates (receptor mosaics) via oligomerization at both pre- and post-synaptic level. These assemblies of receptors together with inter alia single receptors, adapter proteins, G-proteins and ion channels form the membrane bound part of a complex three-dimensional (3D) molecular circuit, the cytoplasmic part of which consists especially of protein kinases, protein phosphatases and phosphoproteins. It is suggested that this molecular circuit has the capability to learn and store information. Thus, engram formation will depend on the resetting of 3D molecular circuits via the formation of new receptor mosaics capable of addressing the transduction of the chemical messages impinging on the cell membrane to certain sets of G-proteins. Short-term memory occurs by a transient stabilization of the receptor mosaics producing the appropriate change in the synaptic weight. Engram consolidation (long-term memory) may involve intracellular signals that translocate to the nucleus to cause the activation of immediate early genes and subsequent formation of postulated adapter proteins which stabilize the receptor mosaics with the formation of long-lived heteromeric receptor complexes. The receptor mosaic hypothesis of the engram formation has been formulated in agreement with the Hebbian rule and gives a novel molecular basis for it by postulating that the pre-synaptic activity change in transmitter and modulator release reorganizes the receptor mosaics at post-synaptic level and subsequently at pre-synaptic level with the formation of novel 3D molecular circuits leading to a different integration of chemical signals impinging on pre- and post-synaptic membranes hence leading to a new value of the synaptic weight. Engram retrieval is brought about by the scanning of the target networks by the highly divergent arousal systems. Hence, a continuous reverberating process occurs both at the level of the neural networks as well as at the level of the 3D molecular circuits within each neuron of the network until the appropriate tuning of the synaptic weights is obtained and, subsequently, the reappearance of the engram occurs. Learning and memory in the basal ganglia is discussed in the frame of the present hypothesis. It is proposed that formation of long-term memories (consolidated receptor mosaics) in the plasma membranes of the striosomal GABA neurons may play a major role in the motivational learning of motor skills of relevance for survival. In conclusion, long-lived heteromeric receptor complexes of high order may be crucial for learning, memory and retrieval processes, where extensive reciprocal feedback loops give rise to coherent synchronized neural activity (binding) essential for a sophisticated information handling by the central nervous system.

Abstract
The role of adenosine deaminase in the interactions between adenosine A(1) and dopamine D(1) receptors was studied in a mouse fibroblast cell line stably cotransfected with human D(1) receptor and A(1) receptor cDNAs (A(1)D(1) cells). Confocal laser microscopy analysis showed a high degree of adenosine deaminase immunoreactivity on the membrane of the A(1)D(1) cells but not of the D(1) cells (only cotransfected with human D(1) receptor cDNAs). In double immunolabelling experiments in A(1)D(1) cells and cortical neurons a marked overlap in the distribution of the A(1) receptor and adenosine deaminase immunoreactivities and of the D(1) receptor and adenosine deaminase immunoreactivities was found. Quantitative analysis of A(1)D(1) cells showed that adenosine deaminase immunoreactivity to a large extent colocalizes with A(1) and D(1) receptor immunoreactivity, respectively. The A(1) receptor agonist caused in A(1)D(1) cells and in cortical neurons coaggregation of A(1) receptors and adenosine deaminase, and of D(1) receptors and adenosine deaminase. The A(1) receptor agonist-induced aggregation was blocked by R-deoxycoformycin, an irreversible adenosine deaminase inhibitor. The competitive binding experiments with the D(1) receptor antagonist [(3)H]SCH-23390 showed that the D(1) receptors had a better fit for two binding sites for dopamine, and treatment with the A(1) receptor agonist produced a disappearance of the high-affinity site for dopamine at the D(1) receptor. R-Deoxycoformycin treatment, which has previously been shown to block the interaction between adenosine deaminase and A(1) receptors, and which is crucial for the high-affinity state of the A(1) receptor, also blocked the A(1) receptor agonist-induced loss of high-affinity D(1) receptor binding. The conclusion of the present studies is that the high-affinity state of the A(1) receptor is essential for the A(1) receptor-mediated antagonistic modulation of D(1) receptors and for the A(1) receptor-induced coaggregates of A(1) and adenosine deaminase, and of D(1) and adenosine deaminase. Thus, the confocal experiments indicate that both A(1) and D(1) receptors form agonist-regulated clusters with adenosine deaminase, where the presence of a structurally intact adenosine deaminase bound to A(1) receptors is important for the A(1)-D(1) receptor-receptor interaction at the level of the D(1) receptor recognition.

Abstract
In 6-hydroxydopamine-lesioned rats, the selective mGlu(5) receptor agonist (RS)-2-Cholro-5-Hydroxyphenylglycine (CHPG, 1-6 microg/10 microl intracerebroventricularly) significantly inhibited contralateral turning induced by quinpirole and, to a lesser extent, that induced by SKF 38393. The inhibitory effects of CHPG on quinpirole-induced turning were significantly potentiated by an adenosine A(2A) receptor agonist (CGS 21680, 0.2 mg/kg IP) and attenuated by an A(2A) receptor antagonist (SCH 58261, 1 mg/kg IP). In rat striatal membranes, CHPG (100-1,000 nM) significantly reduced the affinity of the high-affinity state of D(2) receptors for the agonist, an effect potentiated by CGS 21680 (30 nM). These results show the occurrence of functional interactions among mGlu(5), adenosine A(2A), and dopamine D(2) receptors in the regulation of striatal functioning, and suggest that mGlu(5) receptors may be regarded as alternative/integrative targets for the development of therapeutic strategies in the treatment of Parkinson's disease.

Abstract
Adenosine A2A receptors (A2AR) and dopamine D2 receptors (D2R) are highly concentrated in the striatum, where they are co-localized and exert reciprocal antagonistic interactions. It has been suggested that the A2R/D2R interactions might provide a therapeutic approach for basal ganglia disorders, such as Parkinson's disease, and schizophrenia. In the present work evidence is presented for the existence of an A2AR/D2R interaction in human brain by using quantitative autoradi- ography. The areas analyzed were the dorsal caudate nucleus and putamen. Parallel studies were performed in rat striatal sections. The A2AR agonist CGS 21680 was found to significantly increase IC50 values of competitive inhibition curves of the D2R/D3R antagonist [125I]iodosulpiride vs dopamine both in rat striatal and human striatal brain sections.

Abstract
Evidence for a role of dopaminergic neurotransmission in the motor effects of adenosine antagonists, such as caffeine, is reviewed, based on the existence of specific antagonistic interactions between specific subtypes of adenosine and dopamine receptors in the striatum. Both adenosine A(1) and adenosine A(2A) receptor antagonists induce motor activation in rodents. At least a certain degree of dopaminergic activity is required to obtain adenosine antagonist-induced motor activation, with adenosine A(1) antagonists being the most sensitive and non-selective adenosine antagonists the most resistant to striatal dopamine depletion. When considering long-term treatment with adenosine antagonists concomitant administration of dopamine agonists might be required in order to obtain strong motor effects (cross-sensitization) and to avoid the development of telerance.

Abstract
It has been shown that striatal adenosine A2A receptors can antagonistically interact with dopamine D2 receptors at the membrane level leading to a decrease in the affinity and efficacy of D2 receptors. Extracellular recordings and rotational behaviour were employed to obtain a correlate to these findings in an animal model of Parkinson's disease (PD). The recordings were performed in rats with unilateral 6-hydroxydopamine (6-OHDA)-induced catecholamine depletion. While recording in the dopamine-depleted striatum, local applications of the dopamine D2 agonist quinpirole reduced neuronal activity. However, when the adenosine A2A antagonist MSX-3 was applied simultaneously with quinpirole, the inhibition of neuronal firing seen after quinpirole alone was significantly potentiated (P< 0.001, n = 11). In contrast, local application of CGS 21680 attenuated the effect of quinpirole. The doses of MSX-3 and CGS 21680 used to achieve the modulation of quinpirole action had no effect per se on striatal neuronal firing. Furthermore, rotational behaviour revealed that MSX-3 dose-dependently increased the number of turns when administrated together with a threshold dose of quinpirole while no enhancement was achieved when MSX-3 was combined with SKF 38393. MSX-3 alone did not induce rotational behaviour. In conclusion, this study shows that low ineffective doses of MSX-3 enhance the effect of quinpirole on striatal firing rate, while the A2A agonist exerts the opposite action. This mechanism gives a therapeutic potential to A2A antagonists in the treatment of PD by enhancing D2 receptor function.

Abstract
Evidence has been obtained for adenosine/dopamine interactions in the central nervous system. There exists an anatomical basis for the existence of functional interactions between adenosine A(1)R and dopamine D(1)R and between adenosine A(2A) and dopamine D(2) receptors in the same neurons. Selective A(1)R agonists affect negatively the high affinity binding of D(1) receptors. Activation of A(2A) receptors leads to a decrease in receptor affinity for dopamine agonists acting on D(2) receptors, specially of the high-affinity state. These interactions have been reproduced in cell lines and found to be of functional significance. Adenosine/dopamine interactions at the behavioral level probably reflect those found at the level of dopamine receptor binding and transduction. All these findings suggest receptor subtype-specific interactions between adenosine and dopamine receptors that may be achieved by molecular interactions (e.g., receptor heterodimerization). At the molecular level adenosine receptors can serve as a model for homomeric and heteromeric protein-protein interactions. A1R forms homodimers in membranes and also form high-order molecular structures containing also heterotrimeric G-proteins and adenosine deaminase. The occurrence of clustering also clearly suggests that G-protein- coupled receptors form high-order molecular structures, in which multimers of the receptors and probably other interacting proteins form functional complexes. In view of the occurrence of homodimers of adenosine and of dopamine receptors it is speculated that heterodimers between these receptors belonging to two different families of G-protein-coupled receptors can be formed. Evidence that A1/D1 can form heterodimers in cotransfected cells and in primary cultures of neurons has in fact been obtained. In the central nervous system direct and indirect receptor-receptor interactions via adaptor proteins participate in neurotransmission and neuromodulation and, for example, in the establishment of high neural functions such as learning and memory.

Abstract
The possible molecular basis for the previously described antagonistic interactions between adenosine A(1) receptors (A(1)R) and dopamine D(1) receptors (D(1)R) in the brain have been studied in mouse fibroblast Ltk(-) cells cotransfected with human A(1)R and D(1)R cDNAs or with human A(1)R and dopamine D(2) receptor (long-form) (D(2)R) cDNAs and in cortical neurons in culture. A(1)R and D(1)R, but not A(1)R and D(2)R, were found to coimmunoprecipitate in cotransfected fibroblasts. This selective A(1)R/D(1)R heteromerization disappeared after pretreatment with the D(1)R agonist, but not after combined pretreatment with D(1)R and A(1)R agonists. A high degree of A(1)R and D(1)R colocalization, demonstrated in double immunofluorescence experiments with confocal laser microscopy, was found in both cotransfected fibroblast cells and cortical neurons in culture. On the other hand, a low degree of A(1)R and D(2)R colocalization was observed in cotransfected fibroblasts. Pretreatment with the A(1)R agonist caused coclustering (coaggregation) of A(1)R and D(1)R, which was blocked by combined pretreatment with the D(1)R and A(1)R agonists in both fibroblast cells and in cortical neurons in culture. Combined pretreatment with D(1)R and A(1)R agonists, but not with either one alone, substantially reduced the D(1)R agonist-induced accumulation of cAMP. The A(1)R/D(1)R heteromerization may be one molecular basis for the demonstrated antagonistic modulation of A(1)R of D(1)R receptor signaling in the brain. The persistence of A(1)R/D(1)R heteromerization seems to be essential for the blockade of A(1)R agonist-induced A(1)R/D(1)R coclustering and for the desensitization of the D(1)R agonist-induced cAMP accumulation seen on combined pretreatment with D(1)R and A(1)R agonists, which indicates a potential role of A(1)R/D(1)R heteromers also in desensitization mechanisms and receptor trafficking.

Abstract
Rat dopamine D(2short) expressed in Chinese hamster ovary (CHO) cells were characterized by means of activation of [(35)S]-guanosine 5'-O-(gamma-thiotriphosphate) ([(35)S]GTPgammaS) binding and inhibition of [(3)H]raclopride binding. Among 18 dopaminergic ligands studied dopamine, NPA, apomorphine and quinpirole were full agonists in activation of [(35)S]GTPgammaS binding, while seven ligands were partial agonists with efficacies from 16 to 69% of the effect of dopamine and seven ligands were antagonists having no effect on the basal level of [(35)S]GTPgammaS binding, but inhibited dopamine-dependent activation in a dose-response manner. Despite the different efficacies, the potencies of all 18 ligands to modulate [(35)S]GTPgammaS binding revealed a good correlation with their potencies to inhibit [(3)H]raclopride binding in the CHO cell membranes. This indicates that the binding of the ligand to the receptor determines its potency, but has no direct correlation with its intrinsic activity.

Abstract
Adenosine can influence dopaminergic neurotransmission in the basal ganglia via postsynaptic interaction between adenosine A2A and dopamine D2 receptors. We have used a human neuroblastoma cell line (SH-SY5Y) that was found to express constitutively moderate levels of adenosine A1 and A2A receptors (approximately 100 fmol/mg of protein) to investigate the interactions of A2A/D2 receptors, at a cellular level. After transfection with human D2L receptor cDNA, SH-SY5Y cells expressed between 500 and 1,100 fmol of D2 receptors/mg of protein. In membrane preparations, stimulation of adenosine A2A receptors decreased the affinity of dopamine D2 receptors for dopamine. In intact cells, the calcium concentration elevation induced by KCI treatment was moderate, and dopamine had no effect on either resting intracellular free Ca2+ concentration ([Ca2+]i) or KCI-induced responses. In contrast, pretreatment with adenosine deaminase for 2 days dramatically increased the elevation of [Ca2+]i evoked by KCI, which then was totally reversed by dopamine. The effects induced by 48-h adenosine inactivation were mimicked by application of adenosine A1 antagonists and could not be further reversed by acute activation of either A1 or A2A receptors. Acute application of the selective A2 receptor agonist CGS-21680 counteracted the D2 receptor-induced [Ca2+]i responses. The present study shows that SH-SY5Y cells are endowed with functional adenosine A2A and A1 receptors and that A2A receptors exert an antagonistic acute effect on dopamine D2 receptor-mediated functions. In contrast, A1 receptors induce a tonic modulatory role on these dopamine functions.

Abstract
It has been previously found that the systemic administration of low doses of N-methyl-D-aspartate (NMDA) in mice induces motor depression. The effects of the systemic administration of different doses of NMDA (10, 30 and 60 mg/kg s.c.) on the motor activity and on the in vivo extracellular levels of adenosine in the striatum was studied in Sprague-Dawley rats. The adenosine concentration in samples of perfusate was determined 24 h after implantation of a transverse microdialysis probe. At 30 and 60 mg/kg, but not 10 mg/kg, NMDA induced both a significant motor depression (motility and rearing) and a significant increase in the striatal extracellular levels of adenosine. Both the motor depression and the changes in the extracellular levels of adenosine were only evident during the first 30 min after NMDA administration. The non-competitive NMDA receptor antagonist MK-801 (0.1 mg/kg s.c.) completely counteracted the effects of NMDA (30 mg/kg s.c.) on motor activity (motility) and on the striatal extracellular levels of adenosine. The correlation between the behavioural and the biochemical data strongly support the hypothesis that adenosine release in the striatum is a main mechanism responsible for the motor depressant effects produced by the systemic administration of NMDA.

Abstract
Adenosine A1 receptors antagonistically and specifically modulate the binding and functional characteristics of dopamine D1 receptors. In the striatum this interaction seems to take place in the GABAergic strionigro-strioentopeduncular neurons, where both receptors are colocalized. D1 receptors in the strionigro-strioentopeduncular neurons are involved in the increased striatal expression of immediate-early genes induced by the systemic administration of psychostimulants and D1 receptor agonists. Previous results suggest that a basal expression of the immediate-early gene c-fos tonically facilitates the functioning of strionigro-strioentopeduncular neurons and facilitates D1 receptor-mediated motor activation. The role of A1 receptors in the modulation of the expression of striatal D1 receptor-regulated immediate-early genes and the D1 receptor-mediated motor activation was investigated in rats with a unilateral lesion of the ascending dopaminergic pathways. The systemic administration of the A1 agonist N6-cyclopentyladenosine (CPA, 0.1 mg/kg) significantly decreased the number of contralateral turns induced by the D1 agonist SKF 38393 (3 mg/kg). Higher doses of CPA (0.5 mg/kg) were necessary to inhibit the turning behaviour induced by the D2 agonist quinpirole (0.1 mg/kg). By using in situ hybridization it was found that CPA (0.1 mg/kg) significantly inhibited the SKF 38393-induced increase in the expression of NGFI-A and c-fos mRNA levels in the dopamine-denervated striatum. The increase in jun-B mRNA expression could only be inhibited with the high dose of CPA (0.5 mg/kg). A stronger effect of the A1 agonist was found in the ventral striatum (nucleus accumbens) compared with the dorsal striatum (dorsolateral caudate-putamen). The results indicate the existence of antagonistic A1-D1 receptor-receptor interactions in the dopamine-denervated striatum controlling D1 receptor transduction at supersensitive D1 receptors.

Abstract
Human adenosine A2A and rat dopamine D2 receptors (A2A and D2 receptors) were co-transfected in Chinese hamster ovary (CHO) cells to study the interactions between two receptors that are co-localized in striatopallidal gamma-aminobutyric acid-(GABA)ergic neurons. Membranes from transfected cells showed a high density of D2 (3.6 pmol per mg protein) and A2A receptors (0.56 pmol per mg protein). The D2 receptors were functional: an agonist, quinpirole, could stimulate GTPgammaS binding and reduce stimulated adenylyl cyclase activity. The A2A receptor agonist 2-p-(2-carboxyethyl)phenethylamino-5'-N-ethylcarboxamidoadenosine (CGS 21680) decreased high-affinity binding of the agonist dopamine at D2 receptors. Activation of adenosine A2A receptors shifted the dose-response curve for quinpirole on adenosine 3',5'-cyclic monophosphate (cAMP) to the right. However, CGS 21680 did not affect dopamine D2 receptor-induced GTPgammaS binding, but did cause a concentration-dependent increase in cAMP accumulation. The maximal cAMP response was decreased by the D2 agonist quinpirole in a concentration-dependent manner, but there was no change in EC50 and no effect in cells transfected only with adenosine A2A receptors. A2A receptor activation also increased phosphorylation of cAMP response element-binding protein and expression of c-fos mRNA. These effects were also strongly counteracted by quinpirole. These results show that the antagonistic actions between adenosine A2A and dopamine D2 receptors noted previously in vivo can also be observed in CHO cells where the two receptors are co-transfected. Thus, no brain cell-specific factors are required for such interactions. Furthermore, the interaction at the second messenger level and beyond may be quantitatively more important than A2A receptor-mediated inhibition of high affinity D2 agonist binding to the receptor.

Abstract
Adenosine A2A, group I mGlu and neurotensin receptors have been previously found to modulate the binding characteristics of dopamine D2 receptors in membrane preparations from rat striatum. In the present study it is shown that stimulation of different combinations of striatal A2A, group I mGlu and neurotensin receptors induce different effects on the modulation of D2 receptor binding to those obtained when they are separately stimulated using maximal effective concentrations. In competitive inhibition experiments of dopamine versus the D2 receptor antagonist [3H]raclopride the addition of the A2A receptor agonist CGS 21680, the group I mGlu receptor agonist DHPG or neurotensin induced a decrease in the affinity of the high affinity state of the dopamine D2 receptors for dopamine. When added together CGS 21680 plus neurotensin induced the same effect as when administered alone, CGS 21680 plus DHPG induced a synergistic effect and DHPG plus neurotensin lost their modulating effect on D2 receptor binding. These results demonstrate the existence of multiple intramembrane receptor-receptor interactions in the regulation of striatal D2 receptors.

Abstract
There is experimental evidence from radioligand binding experiments for the existence of strong antagonistic interactions between different subtypes of adenosine and dopamine receptors in the striatum, mainly between adenosine A1 and dopamine D1 and between adenosine A2A and dopamine D2 receptors. These interactions seem to be more powerful in the ventral compared to the dorsal striatum, which might have some implications for the treatment of schizophrenia. The binding characteristics of different dopamine and adenosine receptor subtypes were analysed in the different striatal compartments (dorsolateral striatum and shell and core of the nucleus accumbens), by performing saturation experiments with the dopamine D1 receptor antagonist [125I]SCH-23982, the dopamine D2-3 receptor antagonist [3H]raclopride, the adenosine A1 receptor antagonist [3H]DPCPX and the adenosine A2A receptor antagonist [3H]SCH 58261. The experiments were also performed in rats with a neonatal bilateral lesion of the ventral hippocampus (VH), a possible animal model of schizophrenia. Both dopamine D2-3 and adenosine A2A receptors follow a similar pattern, with a lower density of receptors (40%) in the shell of the nucleus accumbens compared with the dorsolateral caudate-putamen. A lower density of adenosine A1 receptors (20%) was also found in the shell of the nucleus accumbens compared with the caudate-putamen. On the other hand, dopamine D1 receptors showed a similar density in the different striatal compartments. Therefore, differences in receptor densities cannot explain the stronger interactions between adenosine and dopamine receptors found in the ventral, compared to the dorsal striatum. No statistical differences in the binding characteristics of any of the different adenosine and dopamine receptor antagonists used were found between sham-operated and VH-lesioned rats.

Abstract
RAT dopamine D2short receptors expressed in CHO cells were characterized by activation of [35S]GTPgammaS binding. There were no significant differences between the maximal effects seen in activation of [35S]GTPgammaS binding caused by dopaminergic agonists, but the effects of 5-HT, 8OH-DPAT and 5-methoxytryptamine amounted to 47 +/- 7%, 43 +/- 5% and 70 +/- 7% of the dopamine effect, respectively. The dopaminergic antagonist (+)butaclamol inhibited activations of both types of ligands with equal potency (pA2 = 8.9 +/- 0.1), indicating that only one type of receptor is involved. In competition with [3H]raclopride binding, dopaminergic agonists showed 53 +/- 2% of the binding sites in the GTP-dependent high-affinity state, whereas 5-HT showed only 20 +/- 3%. Taken together, the results indicate that serotonergic agonists behave as typical partial agonists for D2 receptors with potential antiparkinsonian activity.

Abstract
There is experimental evidence for the existence of interactions between metabotropic glutamate (mGlu), adenosine and dopamine receptors in the striatum. In membrane preparations from rat striatum the group I and II mGlu receptor agonist 1-aminocyclopentane-1S-3R-dicarboxylic acid (1S-3R-ACPD) was found to modulate the binding characteristics of D2 receptors in a similar manner as the A2A receptor agonist 2-[p-(2-carboxyethyl)phenthylamino]-5'-N-ethylcarboxamidoadenosine (CGS 21680), with a significant decrease in the affinity of the high-affinity state of D2 receptors for dopamine. The effect of 1S-3R-ACPD was mimicked by (+/-)-trans-ACPD (t-ACPD; a racemic mixture of 1S-3R-ACPD and its inactive isomer 1R-3S-ACPD) and by the selective group I mGlu receptor agonist 3,5-dihydroxyphenylglycine (DHPG) and it was counteracted by the selective group I mGlu receptor antagonist 1-aminoindan-1,5-dicarboxilic acid (AIDA), but not by the the group II and III mGlu receptor antagonist (RS)-alpha-methyl-4-tetrazolylphenylglycine (MTPG) or the adenosine receptor antagonist 8-phenyltheophylline. Furthermore, a strong synergistic effect was observed when the striatal membranes were exposed to both CGS 21680 and 1S-3R-ACPD. In agreement with the biochemical results, in unilaterally 6-OH-dopamine lesioned rats 1S-3R-ACPD counteracted the turning behaviour induced by the D2 receptor agonist quinpirole, but not by the D1 receptor agonist SKF 38393, and it synergistically potentiated the antagonistic effect of CGS 21680 on quinpirole-induced turning behaviour.

Abstract
The motor effects of selective adenosine A1 and A2A receptor antagonists were tested in young (2 months) and aged (24 months) Wistar rats. In young rats, both the selective A2A receptor antagonist 5-amino-7-(2-phenylethyl)-2-2(2-furyl)-pyrazolo[4,3-e]-1,2,4-triazo++ + lo[1,5-c]pyrimidine (SCH 58261, minimal effective dose 2 mg/kg intraperitoneally (i.p.)) and the selective A1 receptor antagonist 8-cyclopentyl-1,3-dimethylxanthine (CPT, minimal effective dose 1.2 mg/kg i.p.) stimulated motor activity. In old rats, both compounds induced significant motor activation starting from doses lower than those required in young animals. Specifically, the minimal effective doses of SCH 58261 and CPT in aged rats were 1 and 0.6 mg/kg i.p, respectively. The results indicate that both adenosine A1 and A2A receptors play a functional role in the control of motor activity, and, therefore, the blockade of both receptor subtypes is involved in the motor stimulating properties of methylxanthines. Also the evidence indicates, for the first time, that in aged animals the motor inhibitory adenosinergic tone seems to be increased with respect to young animals.

Abstract
An antagonistic interaction between adenosine A2A- and dopamine D2-receptors has been described. Radioligand binding experiments showed a predominant reduction in the number of D2 vs. A2A-receptors in the striatum of aged compared to young rats. The A2A-receptor-mediated antagonistic modulation of D2-receptor binding remained unchanged in aged animals. In striatal homogenates a significant increase in adenosine and no change in dopamine content was found in aged vs. young rats. These results reveal the existence of an age-dependent imbalance of adenosine vs. dopamine in favor of adenosine, which involves both presynaptic and postsynaptic mechanisms.

Abstract
An analysis at the network and membrane level has provided evidence that antagonistic interactions between adenosine A2A/dopamine D2 and adenosine A1/dopamine D1 receptors in the ventral and dorsal striatum are at least in part responsible for the motor stimulant effects of adenosine receptor antagonists like caffeine and for the motor depressant actions of adenosine receptor agonists. The results obtained in stably cotransfected cells also underline the hypothesis that the intramembrane A2A/D2 and A1/D1 receptor interactions represent functionally important mechanisms that may be the major mechanism for the demonstrated antagonistic A2A/D2 and A1/D1 receptor interactions found in vivo in behavioural studies and in studies on in vivo microdialysis of the striopallidal and strioentopeduncular GABAergic pathways. A major mechanism for the direct intramembrane A2A/D2 and A1/D1 receptor interactions may involve formation of A2A/D2 and A1/D1 heterodimers leading to allosteric changes that will alter the affinity as well as the G protein coupling and thus the efficacy to control the target proteins in the membranes. This is the first molecular network to cellular integration in the nerve cell membrane and may be well suited for a number of integrated tasks and can be performed in a short-time scale, in comparison with the very long-time scale observed when receptor heteroregulation involves phosphorylation or receptor resynthesis. Multiple receptor-receptor interactions within the membranes through formation of receptor clusters may lead to the storage of information within the membranes. Such molecular circuits can represent hidden layers within the membranes that substantially increase the computational potential of neuronal networks. These molecular circuits are biased and may therefore represent part of the molecular mechanism for the storage of memory traces (engrams) in the membranes.

Abstract
The effects of the systemic (i.p.) administration of the selective adenosine A1 receptor agonist N6-cyclopentyladenosine (CPA) and the selective adenosine A2A receptor agonist sodium 2-p-carboxyethyl)phenylamino-5'-N-carboxamidoadenosine (CGS 21680) on different dopamine receptor agonist-induced behaviours were studied in the male rat. CGS 21680 (1 micromol/kg), but not CPA, was found to counteract the stereotypies induced by the non-selective dopamine receptor agonist apomorphine (0.25 mg/kg s.c.). Low doses of CGS 21680 (0.1 micromol/kg) and high doses of CPA (3 micromol/kg) counteracted yawning induced by the dopamine D2 selective agonist quinpirole (0.05 mg/kg). On the other hand, low doses of CPA (0.3 micromol/kg) antagonized grooming induced by the selective dopamine D1 receptor-selective agonist SKF 38393 (10 mg/kg i.p.), while CGS 21680 was ineffective. These results are consistent with the proposed existence of a selective antagonistic modulation of dopamine D1 and D2 receptors by adenosine A1 and A2A receptors, respectively. The ability of CGS 21680 to counteract apomorphine-induced stereotypies is weaker compared to its previously reported antagonistic effect of amphetamine-induced motor activity. This supports the hypothesis that adenosine A2A receptor agonists may be potential antipsychotic drugs with a low potential for extrapyramidal side effects.

Abstract
OBJECTIVE Analysis of the results obtained in terms of improvement in the continuity of care, its resolutive capacity and accessibility, in the framework of the organisational change brought about by the reorganisation of specialist care (RSC) in the Ciutat Vella Health Sector. DESIGN A descriptive study of the reorganised model of specialist care introduced in 1995 and comparison between this and the previous model (1993) in terms of activity, further tests made, referral to hospital, filling in the clinical history and waiting-list. T SETTING: The experience involved 4 PCTs in the Ciutat Vella Health sector of Barcelona (covering 74,449 people). MEASUREMENTS AND MAIN RESULTS The volume of visits was in general less in 1995, while other types of activity had been incorporated: minor surgery, cryotherapy, consultations and sessions. CONCLUSIONS The model of RSC satisfies the basic objectives for which it was designed. It increased the specialist's ability to resolve the case within Primary Care. It improved user accessibility to specialist care in terms of waiting time. Finally, the model favours ongoing care, thanks to a single clinical history for both levels.

Abstract
The antagonistic interactions between adenosine A1 and dopamine D1 receptors were studied in a mouse Ltk- cell line stably cotransfected with human adenosine A1 receptor and dopamine D1 receptor cDNAs. In membrane preparations, both the adenosine A1 receptor agonist N6-cyclopentyladenosine and the GTP analogue guanyl-5'-yl imidodiphospate induced a decrease in the proportion of dopamine D1 receptors in a high affinity state. In the cotransfected cells, the adenosine A1 agonist induced a concentration-dependent inhibition of dopamine-induced cAMP accumulation. Blockade of adenosine A1 receptor signal transduction with the adenosine A1 receptor antagonist 1,3-dipropyl-8-cyclopentylxanthine or with pertussis toxin pretreatment increased both basal and dopamine-stimulated cAMP levels, indicating the existence of tonic adenosine A1 receptor activation. Pretreatment with pertussis toxin also counteracted the effects of low concentrations of the A1 agonist on D1 receptor-agonist binding. The results suggest that adenosine A1 receptors antagonistically modulate dopamine D1 receptors at the level of receptor binding and the generation of second messengers.
