Abstract
Huntington's disease (HD) is a neurodegenerative genetic disorder caused by a CAG repeat expansion in the huntingtin gene. HD causes motor, cognitive, and behavioral dysfunction. Since no existing treatment affects the course of this disease, new treatments are needed. Inflammation is frequently observed in HD patients before symptom onset. Neuroinflammation, characterized by the presence of reactive microglia, astrocytes and inflammatory factors within the brain, is also detected early. However, in comparison to other neurodegenerative diseases, the role of neuroinflammation in HD is much less known. Work has been dedicated to altered microglial and astrocytic functions in the context of HD, but less attention has been given to glial participation in neuroinflammation. This review describes evidence of inflammation in HD patients and animal models. It also discusses recent knowledge on neuroinflammation in HD, highlighting astrocyte and microglia involvement in the disease and considering anti-inflammatory therapeutic approaches.

Abstract
Accumulation of misfolded proteins is a common phenomenon of several neurodegenerative diseases. The misfolding of proteins due to abnormal polyglutamine (PolyQ) expansions are linked to the development of PolyQ diseases including Huntington's disease (HD). Though the genetic basis of PolyQ repeats in HD remains prominent, the primary molecular basis mediated by PolyQ toxicity remains elusive. Accumulation of misfolded proteins in the ER or disruption of ER homeostasis causes ER stress and activates an evolutionarily conserved pathway called Unfolded protein response (UPR). Protein homeostasis disruption at organelle level involving UPR or ER stress response pathways are found to be linked to HD. Due to dynamic intricate connections between ER and mitochondria, proteins at ER-mitochondria contact sites (mitochondria associated ER membranes or MAMs) play a significant role in HD development. The current review aims at highlighting the most updated information about different UPR pathways and their involvement in HD disease progression. Moreover, the role of MAMs in HD progression has also been discussed. In the end, the review has focused on the therapeutic interventions responsible for ameliorating diseased states via modulating either ER stress response proteins or modulating the expression of ER-mitochondrial contact proteins.

Cerebral dopamine neurotrophic factor (CDNF) protects against quinolinic acid-induced toxicity in in vitro and in vivo models of Huntington's disease. Sci Rep 2020; 10:19045.

Abstract
Huntington’s disease (HD) is a neurodegenerative disorder with a progressive loss of medium spiny neurons in the striatum and aggregation of mutant huntingtin in the striatal and cortical neurons. Currently, there are no rational therapies for the treatment of the disease. Cerebral dopamine neurotrophic factor (CDNF) is an endoplasmic reticulum (ER) located protein with neurotrophic factor (NTF) properties, protecting and restoring the function of dopaminergic neurons in animal models of PD more effectively than other NTFs. CDNF is currently in phase I–II clinical trials on PD patients. Here we have studied whether CDNF has beneficial effects on striatal neurons in in vitro and in vivo models of HD. CDNF was able to protect striatal neurons from quinolinic acid (QA)-induced cell death in vitro via increasing the IRE1α/XBP1 signalling pathway in the ER. A single intrastriatal CDNF injection protected against the deleterious effects of QA in a rat model of HD. CDNF improved motor coordination and decreased ataxia in QA-toxin treated rats, and stimulated the neurogenesis by increasing doublecortin (DCX)-positive and NeuN-positive cells in the striatum. These results show that CDNF positively affects striatal neuron viability reduced by QA and signifies CDNF as a promising drug candidate for the treatment of HD.

A Combinatorial Cell and Drug Delivery Strategy for Huntington's Disease Using Pharmacologically Active Microcarriers and RNAi Neuronally-Committed Mesenchymal Stromal Cells.

Abstract
For Huntington's disease (HD) cell-based therapy, the transplanted cells are required to be committed to a neuronal cell lineage, survive and maintain this phenotype to ensure their safe transplantation in the brain. We first investigated the role of RE-1 silencing transcription factor (REST) inhibition using siRNA in the GABAergic differentiation of marrow-isolated adult multilineage inducible (MIAMI) cells, a subpopulation of MSCs. We further combined these cells to laminin-coated poly(lactic-co-glycolic acid) PLGA pharmacologically active microcarriers (PAMs) delivering BDNF in a controlled fashion to stimulate the survival and maintain the differentiation of the cells. The PAMs/cells complexes were then transplanted in an ex vivo model of HD. Using Sonic Hedgehog (SHH) and siREST, we obtained GABAergic progenitors/neuronal-like cells, which were able to secrete HGF, SDF1 VEGFa and BDNF, of importance for HD. GABA-like progenitors adhered to PAMs increased their mRNA expression of NGF/VEGFa as well as their secretion of PIGF-1, which can enhance reparative angiogenesis. In our ex vivo model of HD, they were successfully transplanted while attached to PAMs and were able to survive and maintain this GABAergic neuronal phenotype. Together, our results may pave the way for future research that could improve the success of cell-based therapy for HDs.

Abstract
As research progresses in the understanding of the molecular and cellular mechanisms underlying neurodegenerative diseases like Huntington's disease (HD) and expands towards preclinical work for the development of new therapies, highly relevant animal models are increasingly needed to test new hypotheses and to validate new therapeutic approaches. In this light, we characterized an excitotoxic lesion model of striatal dysfunction in non-human primates (NHPs) using cognitive and motor behaviour assessment as well as functional imaging and post-mortem anatomical analyses. NHPs received intra-striatal stereotaxic injections of quinolinic acid bilaterally in the caudate nucleus and unilaterally in the left sensorimotor putamen. Post-operative MRI scans showed atrophy of the caudate nucleus and a large ventricular enlargement in all 6 NHPs that correlated with post-mortem measurements. Behavioral analysis showed deficits in 2 analogues of the Wisconsin card sorting test (perseverative behavior) and in an executive task, while no deficits were observed in a visual recognition or an episodic memory task at 6 months following surgery. Spontaneous locomotor activity was decreased after lesion and the incidence of apomorphine-induced dyskinesias was significantly increased at 3 and 6 months following lesion. Positron emission tomography scans obtained at end-point showed a major deficit in glucose metabolism and D2 receptor density limited to the lesioned striatum of all NHPs compared to controls. Post-mortem analyses revealed a significant loss of medium-sized spiny neurons in the striatum, a loss of neurons and fibers in the globus pallidus, a unilateral decrease in dopaminergic neurons of the substantia nigra and a loss of neurons in the motor and dorsolateral prefrontal cortex. Overall, we show that this robust NHP model presents specific behavioral (learning, execution and retention of cognitive tests) and metabolic functional deficits that, to the best of our knowledge, are currently not mimicked in any available large animal model of striatal dysfunction. Moreover, we used non-invasive, translational techniques like behavior and imaging to quantify such deficits and found that they correlate to a significant cell loss in the striatum and its main input and output structures. This model can thus significantly contribute to the pre-clinical longitudinal evaluation of the ability of new therapeutic cell, gene or pharmacotherapy approaches in restoring the functionality of the striatal circuitry.

Abstract
Increasing evidence in recent years indicates that protein misfolding and aggregation, leading to ER stress, are central factors of pathogenicity in neurodegenerative diseases. This is particularly true in Huntington's disease (HD), where in contrast with other disorders, the cause is monogenic. Mutant huntingtin interferes with many cellular processes, but the fact that modulation of ER stress and of the unfolded response pathways reduces the toxicity, places these mechanisms at the core and gives hope for potential therapeutic approaches. There is currently no effective treatment for HD and it has a fatal outcome a few years after the start of symptoms of cognitive and motor impairment. Here we will discuss recent findings that shed light on the mechanisms of protein misfolding and aggregation that give origin to ER stress in neurodegenerative diseases, focusing on Huntington's disease, on the cellular response and on how to use this knowledge for possible therapeutic strategies.

Abstract
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder associated with abnormal protein modification, inflammation and memory impairment. Aggregated amyloid beta (Aβ) and phosphorylated tau proteins are medical diagnostic features. Loss of memory in AD has been associated with central cholinergic dysfunction in basal forebrain, from where the cholinergic circuitry projects to cerebral cortex and hippocampus. Various reports link AD progression with declining activity of cholinergic neurons in basal forebrain. The neurotrophic molecule, nerve growth factor (NGF), plays a major role in the maintenance of cholinergic neurons integrity and function, both during development and adulthood. Numerous studies have also shown that NGF contributes to the survival and regeneration of neurons during aging and in age-related diseases such as AD. Changes in neurotrophic signaling pathways are involved in the aging process and contribute to cholinergic and cognitive decline as observed in AD. Further, gradual dysregulation of neurotrophic factors like NGF and brain derived neurotrophic factor (BDNF) have been reported during AD development thus intensifying further research in targeting these factors as disease modifying therapies against AD. Today, there is no cure available for AD and the effects of the symptomatic treatment like cholinesterase inhibitors (ChEIs) and memantine are transient and moderate. Although many AD treatment studies are being carried out, there has not been any breakthrough and new therapies are thus highly needed. Long-term effective therapy for alleviating cognitive impairment is a major unmet need. Discussion and summarizing the new advancements of using NGF as a potential therapeutic implication in AD are important. In summary, the intent of this review is describing available experimental and clinical data related to AD therapy, priming to gain additional facts associated with the importance of NGF for AD treatment, and encapsulated cell biodelivery (ECB) as an efficient tool for NGF delivery.

Abstract
The delivery of neurotrophic factors to the central nervous system (CNS) has gained considerable attention as a potential treatment strategy for neurodegenerative disorders such as Huntington's disease (HD). In the present study, we directly compared the ability of two neurotrophic factors, ciliary neurotrophic factor (CNTF), and neurotrophin-4/5 (NT-4/5), to prevent the degeneration of striatal neurons following intrastriatal injections of quinolinic acid (QA). Expression vectors containing either the human CNTF or NT-4/5 gene were transfected into a baby hamster kidney fibroblast cell line (BHK). Using a polymeric device, encapsulated BHK-control cells and those secreting either CNTF (BHK-CNTF) or NT-4/5 (BHK-NT-4/5) were transplanted unilaterally into the rat lateral ventricle. Seven days later, the same animals received unilateral injections of QA (225 nmol) into the ipsilateral striatum. Nissl-stained sections demonstrated that the BHK-CNTF cells significantly reduced the volume of striatal damage produced by QA. Quantitative analysis of striatal neurons further demonstrated that both choline acetyltransferase (ChAT)- and glutamic acid decarboxylase (GAD)-immunoreactive neurons were protected by CNTF implants. In contrast, the volume of striatal damage and loss of striatal ChAT and GAD-positive neurons in animals receiving BHK-NT-4/5 implants did not differ from control-implanted animals. These results help better define the scope of neuronal protection that can be afforded following cellular delivery of various neurotrophic factors. Moreover, these data further support the concept that implants of polymer-encapsulated CNTF-releasing cells can be used to protect striatal neurons from excitotoxic damage, and that this strategy may ultimately prove relevant for the treatment of HD.

Abstract
Huntington's disease (HD) is a devastating genetic disorder with no effective treatments for preventing or lessening the underlying neuronal degeneration. Intracerebral delivery of CNTF in animal models of HD has shown considerable promise as a means of protecting striatal neurons that would otherwise be destined to die. The present study examines whether the neuroprotective effects of CNTF require that the delivery be immediately proximal to the lesion site or whether protective effects can be exerted when the delivery site is more distal to the site of injury. Encapsulated CNTF-producing cells were implanted into the lateral ventricle either ipsilateral or contralateral to an intrastriatal quinolinic acid (QA) injection. A robust neuroprotective effect was observed only in those animals receiving CNTF implants ipsilateral to the QA injection. In these animals, the loss of striatal ChAT and GAD activity as well as the behavioral impairments that resulted from QA were completely prevented. In contrast, no neurochemical or behavioral benefits were produced by implants of CNTF-producing cells in the contralateral ventricle. These data continue to support the use of cellular delivery of CNTF for HD but caution that delivery directly to the striatum may be needed if any clinical benefits are to be seen.

Abstract
Intracerebral delivery of hCNTF has shown considerable neuroprotective potential in animal models of Huntington's disease (HD). The present study describes the relationship between a range of hCNTF doses and the resulting behavioral and neurochemical (striatal ChAT and GAD activity) protection in a rodent model of HD. Encapsulated BHK delivering a range of hCNTF doses were implanted into the lateral ventricle ipsilateral to an intrastriatal quinolinic acid (QA) injection. Results demonstrated a dose-dependent effect of hCNTF with complete, partial, and no observable neuroprotection occurring with preimplant doses of hCNTF of 30.8, 8.6, and 0.8–2.1 ng hCNTF/24 h, respectively. These data continue to support the use of cellular delivery of hCNTF for HD and will facilitate the optimization of this approach in the clinical situation.

Abnormal expansion of a polyglutamine tract in huntingtin (Htt) protein results in Huntington's disease (HD), an autosomal dominant neurodegenerative disorder involving progressive loss of motor and cognitive function. Contrasting with the ubiquitous tissue expression of polyglutamine-expanded Htt, HD pathology is characterized by the increased vulnerability of specific neuronal populations within the striatum and the cerebral cortex. Morphological, biochemical, and functional characteristics of neurons affected in HD that might render these cells more vulnerable to the toxic effects of polyglutamine-Htt are covered in this review. The differential vulnerability of neurons observed in HD is discussed in the context of various major pathogenic mechanisms proposed to date, and in line with evidence showing a 'dying-back' pattern of degeneration in affected neuronal populations.

Abstract
Maintenance and plasticity of striatal neurons is dependent on brain-derived neurotrophic factor (BDNF), which is depleted in the Huntington's disease striatum due to reduced expression and disrupted corticostriatal transportation. In this study we demonstrate that overexpression of BDNF in the striatum attenuates motor impairment and reduces the extent of striatal damage following quinolinic acid lesioning. Transfer of the BDNF gene to striatal neurons using serotype 1/2 adeno-associated viral vectors enhanced BDNF protein levels in the striatum, but induced weight loss and seizure activity following long-term high-level expression. Lower concentration BDNF expression supported striatal neurons against excitotoxic insult, as demonstrated by enhanced krox-24 immunopositive neuron survival, reduction of striatal atrophy and maintenance of the patch/matrix organization. Additionally, BDNF expression attenuated motor impairment in the forelimb use cylinder test, sensorimotor neglect in the corridor food selection task and reversed apomorphine-induced rotational behaviour. Direct correlations were shown for the first time between BDNF-mediated attenuation of behavioural impairment and the integrity of the globus pallidus, seemingly independent from the severity of striatal lesioning. These results demonstrate that BDNF holds considerable therapeutic potential for alleviating both neuropathological and motor function deficits in the Huntington's disease brain, and the critical role of pallidal neurons in facilitating motor performance.

Abstract
The droplet breakup technique with an immiscible liquid coflowing stream was investigated for the preparation of mammalian cell-enclosing subsieve-sized capsules of less than 100 microm in diameter. The major parts of the droplet generation device were a needle of several hundred micrometers in diameter for extruding the cell-suspending sodium alginate aqueous solution and a tubule of 2.5 mm in diameter through which the extruded alginate solution flowed into ambient immiscible liquid paraffin. The needle was positioned upstream in the vicinity of the coaxial tubule. The droplet diameter of the viscous sodium alginate aqueous solution could be controlled from several dozen to several hundred micrometers by changing the velocities of the inner and ambient fluids and the diameter of the needle. By utilizing a 300-microm diameter needle, CHO-K1 cell-enclosing droplets of 48 +/- 8 microm in diameter were obtained by extruding a cell-suspending sodium alginate solution at a velocity of 1.2 cm/sec into the ambient liquid paraffin flowing at a velocity of 23.5 cm/sec. The breakup process did not influence the viability of the enclosed cells, since more than 95% of the CHO-K1 cells remained alive after the enclosing process.

Abstract
Huntington's disease is a neurodegenerative disorder characterized by the selective loss of striatal neurons and, to a lesser extent, cortical neurons. The neurodegenerative process is caused by the mutation of huntingtin gene. Recent studies have established a link between mutant huntingtin, excitotoxicity and neurotrophic factors. Neurotrophic factors prevent cell death in degenerative processes but they can also enhance growth and function of neurons that are affected in Huntington's disease. The endogenous regulation of the expression of neurotrophic factors and their receptors in the striatum and its connections can be important to protect striatal cells and maintains basal ganglia connectivity. The administration of exogenous neurotrophic factors, in animal models of Huntington's disease, has been used to characterize the trophic requirements of striatal and cortical neurons. Neurotrophins, glial cell line-derived neurotrophic factor family members and ciliary neurotrophic factor have shown a potent neuroprotective effects on different neuronal populations of the striatum. Furthermore, they are also useful to maintain the integrity of the corticostriatal pathway. Thus, these neurotrophic factors may be suitable for the development of a neuroprotective therapy for neurodegenerative disorders of the basal ganglia.

Abstract
Neurotrophic factors exert considerable neuroprotective and neurorestorative effects in neurodegenerative diseases. Because neuronal progenitor cells have, at least in part, the potency to restore degenerated neuronal networks, transgenic high-dosage expression of neurotrophins by these cells in neurotransplantation may be advantageous. In the present study, a retroviral vector containing the gene of rat ciliary neurotrophic factor (rCNTF) was permanently transfected into a striatal neuronal progenitor cell line. Qualitative and quantitative analyses demonstrated a sustained expression of the transgene; i.e., rCNTF was present at the mRNA level and protein level. Moreover, cocultivation in separate chambers of transgenic CNTF-ST14A cells and CNTF-dependent TF1 cells exerted typical biological effects, such as increased proliferation and differentiation of the TF1 cells, indicating the functional integrity of the secreted recombinant neurotrophin. The CNTF-ST14A cells displayed improved stress response compared with native ST14A cells under differentiation conditions, i.e., at the nonpermissive temperature of 39 degrees C and after staurosporine exposure, respectively. This effect coincided with a relatively reduced apoptosis rate and a raised metabolic activity of CNTF-ST14A cells at 39 degrees C. Neurotransplantation of CNTF-ST14A cells in the rat quinolinic acid model of Huntington's disease showed a significant and sustained decline in pathological apomorphine-induced rotations compared with parental ST14A cells. We conclude that sustained functional transgene CNTF production improves stress response as well as metabolic activity, making CNTF-ST14A cells a promising tool for neurotransplantation in the quinolinic acid model of Huntington's disease.

Abstract
1. The present study compared the effects of acute intrastriatal administration of quinolinic acid (QA) and 3-nitropropionic acid (3-NP), two neurotoxins used in animal models of Huntington's disease (HD), on the following behavioral and histological measures: (1) open field activity levels; (2) performance on balance beam and grip strength tasks; (3) acquisition of a radial-arm-water-maze (RAWM) task; (4) size of striatum and lateral ventricles; (5) amount of cytochrome oxidase (CYO) labeling; and (6) counts of Nissl-stained neurons and NADPH-diaphorase-labeled neurons in the striatum. 2. Rats were given bilateral intrastriatal injections of either 200 nmol QA, 750 nmol 3-NP, or phosphate buffered saline (PBS) two weeks prior to behavioral testing and four weeks prior to histological processing. 3. The behavioral results indicated that both QA and 3-NP injections caused an increase in activity levels at two weeks postlesion, but only the QA rats showed hyperactivity at four weeks postlesion. Both QA and 3-NP rats showed significant impairment in the balance beam task, but only 3-NP rats differed significantly on the grip-strength task. Both toxins caused learning impairments in the RAWM task, with 3-NP rats being more severely impaired. 4. The neuroanatomical results indicated that both QA and 3-NP produced significant striatal atrophy and ventricular dilation, as well as a reduction in CYO staining and loss of Nissl-stained neurons, but only the 3-NP lesions created necrotic cavities in the striatum. However, the QA treatments resulted in significant loss of NADPH-diaphorase neurons in regions peripheral to the site of injection. 5. In general, these results suggest that QA treatments produce milder behavioral and neuroanatomical effects that mimic some of the earlier symptoms of HD, while 3-NP produced more severe effects which mimic both the later symptoms and the juvenile onset of HD.
