Abstract
Elevated serum IgE levels are associated with allergic disorders, parasitosis and specific immunologic abnormalities. In addition, epidemiological and mechanistic evidence indicates an association between IgE-mediated immune surveillance and protection from tumour growth. Intriguingly, recent studies reveal a correlation between IgE deficiency and increased malignancy risk. This is the first review discussing IgE levels and links to pathological conditions, with special focus on the potential clinical significance of ultra-low serum IgE levels and risk of malignancy. In this Position Paper we discuss: (a) the utility of measuring total IgE levels in the management of allergies, parasitosis, and immunodeficiencies, (b) factors that may influence serum IgE levels, (c) IgE as a marker of different disorders, and d) the relationship between ultra-low IgE levels and malignancy susceptibility. While elevated serum IgE is generally associated with allergic/atopic conditions, very low or absent IgE may hamper anti-tumour surveillance, indicating the importance of a balanced IgE-mediated immune function. Ultra-low IgE may prove to be an unexpected biomarker for cancer risk. Nevertheless, given the early stage of investigations conducted mostly in patients with diseases that influence IgE levels, in-depth mechanistic studies and stratification of malignancy risk based on associated demographic, immunological and clinical co-factors are warranted.

Abstract
BACKGROUND Designing biologically informative models for assessing the safety of novel agents, especially for cancer immunotherapy, carries substantial challenges. The choice of an in vivo system for studies on IgE antibodies represents a major impediment to their clinical translation, especially with respect to class-specific immunological functions and safety. Fcε receptor expression and structure are different in humans and mice, so that the murine system is not informative when studying human IgE biology. By contrast, FcεRI expression and cellular distribution in rats mirror that of humans. METHODS We are developing MOv18 IgE, a human chimeric antibody recognizing the tumour-associated antigen folate receptor alpha. We created an immunologically congruent surrogate rat model likely to recapitulate human IgE-FcεR interactions and engineered a surrogate rat IgE equivalent to MOv18. Employing this model, we examined in vivo safety and efficacy of antitumour IgE antibodies. RESULTS In immunocompetent rats, rodent IgE restricted growth of syngeneic tumours in the absence of clinical, histopathological or metabolic signs associated with obvious toxicity. No physiological or immunological evidence of a "cytokine storm" or allergic response was seen, even at 50 mg/kg weekly doses. IgE treatment was associated with elevated serum concentrations of TNFα, a mediator previously linked with IgE-mediated antitumour and antiparasitic functions, alongside evidence of substantially elevated tumoural immune cell infiltration and immunological pathway activation in tumour-bearing lungs. CONCLUSION Our findings indicate safety of MOv18 IgE, in conjunction with efficacy and immune activation, supporting the translation of this therapeutic approach to the clinical arena.

Abstract
BACKGROUND & AIMS The innate immune system responds not only to bacterial signals, but also to non-infectious danger-associated molecular patterns that activate the NLRP3 inflammasome complex after tissue injury. Immune functions vary over the course of the day, but it is not clear whether these changes affect the activity of the NLRP3 inflammasome. We investigated whether the core clock component nuclear receptor subfamily 1 group D member 1 (NR1D1, also called Rev-erbα) regulates expression, activity of the NLRP3 inflammasome, and its signaling pathway. METHODS We collected naïve peritoneal macrophages and plasma, at multiple times of day, from Nr1d1-/- mice and their Nr1d1+/+ littermates (controls) and analyzed expression NLRP3, interleukin 1β (IL1B, in plasma), and IL18 (in plasma). We also collected bone marrow-derived primary macrophages from these mice. Levels of NR1D1 were knocked down with small hairpin RNAs in human primary macrophages. Bone marrow-derived primary macrophages from mice and human primary macrophages were incubated with lipopolysaccharide (LPS) to induce expression of NLRP3, IL1B, and IL18; cells were incubated with LPS and adenosine triphosphate to activate the NLRP3 complex. We analyzed caspase 1 activity and cytokine secretion. NR1D1 was activated in primary mouse and human macrophages by incubation with SR9009; some of the cells were also incubated with an NLRP3 inhibitor or inhibitors of caspase 1. Nr1d1-/- mice and control mice were given intraperitoneal injections of LPS to induce peritoneal inflammation; plasma samples were isolated and levels of cytokines were measured. Nr1d1-/- mice, control mice, and control mice given injections of SR9009 were given LPS and D-galactosamine to induce fulminant hepatitis and MCC950 to specifically inhibit NLRP3; plasma was collected to measure cytokines and a marker of liver failure (alanine aminotransferase); liver tissues were collected and analyzed by quantitative polymerase chain reaction, immunohistochemistry, and flow cytometry. RESULTS In peritoneal macrophages, expression of NLRP3 and activation of its complex varied with time of day (circadian rhythm)-this regulation required NR1D1. Primary macrophages from Nr1d1-/- mice and human macrophages with knockdown of NR1D1 had altered expression patterns of NLRP3, compared to macrophages that expressed NR1D1, and altered patterns of IL1B and 1L18 production. Mice with disruption of Nr1d1 developed more-severe acute peritoneal inflammation and fulminant hepatitis than control mice. Incubation of macrophage with the NR1D1 activator SR9009 reduced expression of NLRP3 and secretion of cytokines. Mice given SR9009 developed less-severe liver failure and had longer survival times than mice given saline (control). CONCLUSIONS In studies of Nr1d1-/- mice and human macrophages with pharmacologic activation of NR1D1, we found NR1D1 to regulate the timing of NLRP3 expression and production of inflammatory cytokines by macrophages. Activation of NR1D1 reduced the severity of peritoneal inflammation and fulminant hepatitis in mice.

Abstract
While desired for the cure of allergy, regulatory immune cell subsets and nonclassical Th2-biased inflammatory mediators in the tumour microenvironment can contribute to immune suppression and escape of tumours from immunological detection and clearance. A key aim in the cancer field is therefore to design interventions that can break immunological tolerance and halt cancer progression, whereas on the contrary allergen immunotherapy exactly aims to induce tolerance. In this position paper, we review insights on immune tolerance derived from allergy and from cancer inflammation, focusing on what is known about the roles of key immune cells and mediators. We propose that research in the field of AllergoOncology that aims to delineate these immunological mechanisms with juxtaposed clinical consequences in allergy and cancer may point to novel avenues for therapeutic interventions that stand to benefit both disciplines.

Abstract
BACKGROUND Ivermectin (IVM) is widely used in both human and veterinary medicine to treat parasitic infections. Recent reports have suggested that IVM could also have anti-inflammatory properties. METHODS Here, we investigated the activity of IVM in a murine model of atopic dermatitis (AD) induced by repeated exposure to the allergen Dermatophagoides farinae, and in standard cellular immunological assays. RESULTS Our results show that topical IVM improved allergic skin inflammation by reducing the priming and activation of allergen-specific T cells, as well as the production of inflammatory cytokines. While IVM had no major impact on the functions of dendritic cells in vivo and in vitro, IVM impaired T-cell activation, proliferation, and cytokine production following polyclonal and antigen-specific stimulation. CONCLUSION Altogether, our results show that IVM is endowed with topical anti-inflammatory properties that could have important applications for the treatment of T-cell-mediated skin inflammatory diseases.

Abstract
Th2 immunity and allergic immune surveillance play critical roles in host responses to pathogens, parasites and allergens. Numerous studies have reported significant links between Th2 responses and cancer, including insights into the functions of IgE antibodies and associated effector cells in both antitumour immune surveillance and therapy. The interdisciplinary field of AllergoOncology was given Task Force status by the European Academy of Allergy and Clinical Immunology in 2014. Affiliated expert groups focus on the interface between allergic responses and cancer, applied to immune surveillance, immunomodulation and the functions of IgE-mediated immune responses against cancer, to derive novel insights into more effective treatments. Coincident with rapid expansion in clinical application of cancer immunotherapies, here we review the current state-of-the-art and future translational opportunities, as well as challenges in this relatively new field. Recent developments include improved understanding of Th2 antibodies, intratumoral innate allergy effector cells and mediators, IgE-mediated tumour antigen cross-presentation by dendritic cells, as well as immunotherapeutic strategies such as vaccines and recombinant antibodies, and finally, the management of allergy in daily clinical oncology. Shedding light on the crosstalk between allergic response and cancer is paving the way for new avenues of treatment.

Abstract
Interleukin-17A (IL-17A) is a pro-inflammatory cytokine that has an important role at mucosal sites in a wide range of immune responses including infection, allergy and auto-immunity. γδ T cells are recognized as IL-17 producers, but based on the level of CD3 expression, we now define the remarkable ability of a CD3(bright) γδ T-cell subset with an effector memory phenotype to rapidly produce IL-17A, but not interferon-γ. CD3(bright) γδ T cells uniformly express the canonical germline encoded Vγ6/Vδ1(+) T-cell receptor. They are widely distributed with a preferential representation in the lungs and skin are negatively impacted in the absence of retinoic acid receptor-related orphan receptor gammat expression or endogenous flora. This population responded rapidly to various stimuli in a mechanism involving IL-23 and NOD-like receptor family, pyrin domain containing 3 (NLRP3)-inflammasome-dependent IL-1β. Finally, we demonstrated that IL-17-producing CD3(bright) γδ T cells responded promptly and strongly to pneumococcal infection and during skin inflammation. Here, we propose a new way to specifically analyze IL-17-producing Vγ6/Vδ1(+) T cells based on the level of CD3 signals. Using this gating strategy, our data reinforce the crucial role of this γδ T-cell subset in respiratory and skin disorders.

Abstract
Allergic asthma is a T cell-dependent inflammatory lung disease that results from complex interactions between genetic predisposition and environmental factors, including exposure to lipopolysaccharide (LPS). In this study, we have shown that airway LPS exposure was sufficient to induce airway hyperreactivity (AHR) and eosinophil recruitment in mice that had previously experienced an acute episode of allergic asthma. LPS-induced disease reactivation depended on the activation of allergen-specific CD4(+) T cells by a subset of lung langerin(+) dendritic cells (DCs) that retained the allergen. Upon LPS exposure, migration of langerin(+) DCs from lungs to draining lymph nodes increased and LPS-exposed langerin(+) DCs instructed CD4(+) T cells toward a T helper (Th) 2 response. Selective depletion of langerin(+) DCs prevented LPS-induced eosinophil recruitment and T-cell activation, further demonstrating a critical role for langerin(+) DCs in disease reactivation. This finding provides a possible explanation for the subclinical worsening of asthmatics following exposure to low-dose LPS.

Abstract
The prevalence of asthma has steadily increased during the last decade, probably as the result of changes in the environment, including reduced microbial exposure during infancy. Accordingly, experimental studies have shown that deliberate infections with live pathogens prevent the development of allergic airway diseases in mice. Bacterial extracts are currently used in children suffering from repeated upper respiratory tract infections. In the present study, we have investigated whether bacterial extracts, commercially available as Broncho-Vaxom (BV), could prevent allergic airway disease in mice. Oral treatment with BV suppressed airway inflammation through interleukin-10 (IL-10)-dependent and MyD88 (myeloid differentiation primary response gene (88))-dependent mechanisms and induced the conversion of FoxP3 (forkhead box P3)(-) T cells into FoxP3(+) regulatory T cells. Furthermore, CD4(+) T cells purified from the trachea of BV-treated mice conferred protection against airway inflammation when adoptively transferred into sensitized mice. Therefore, treatment with BV could possibly be a safe and efficient strategy to prevent the development of allergic diseases in children.

Abstract
Recently, known eosinophil functions have been extended considerably: previously the cells were thought to have an exclusive role in the release of cytotoxic mediators; now they are known to have roles in antigen presentation and immunoregulation through the release of cytokines. Although questionable, animal models indicate a rather beneficial role of eosinophils in parasitic infections but a detrimental one, together with other cells, in allergy.

Abstract
FcepsilonRI expressed by human eosinophils is involved in IgE-mediated cytotoxicity reactions toward the parasite Schistosoma mansoni in vitro. However, because receptor expression is low on these cells, its functional role is still controversial. In this study, we have measured surface and intracellular expression of FcepsilonRI by blood eosinophils from hypereosinophilic patients and normal donors. The number of unoccupied receptors corresponded to approximately 4,500 Ab binding sites per cell, whereas 50,000 Ab binding sites per cell were detected intracellularly. Eosinophils from patients displayed significantly more unoccupied receptors than cells from normal donors. This number correlated to both serum IgE concentrations and to membrane-bound IgE. The lack of FcepsilonRI expression by mouse eosinophils has hampered further studies. To overcome this fact and experimentally confirm our findings on human eosinophils, we engineered IL-5 x hFcepsilonRIalpha double-transgenic mice, whose bone marrow, blood, spleen, and peritoneal eosinophils expressed FcepsilonRI levels similar to levels of human eosinophils, after 4 days culture with IgE in the presence of IL-5. Both human and mouse eosinophils were able to secrete IL-10 upon FcepsilonRI engagement. Thus, comparative analysis of cells from patients and from a relevant animal model allowed us to clearly demonstrate that FcepsilonRI-mediated eosinophil activation leads to IL-10 secretion. Through FcepsilonRI expression, these cells are able to contribute to both the regulation of the immune response and to its effector mechanisms.

Abstract
Schistosomiasis, the second major parasitic disease in the world after malaria, affects 200 million people. Vaccine strategies represent an essential component of the control of this chronic debilitating disease where the deposition of millions of eggs in the tissues is the main cause of pathology. Research developed in our laboratory over the last 20 years has led to the identification of novel effector mechanisms, pointing for the first time to the protective role of Th2 responses and of IgE antibodies now supported by seven studies in human populations. The identification and molecular cloning of a target antigen, a glutathione S-transferase (GST), has made it possible to demonstrate its vaccine potential in several animal species (rodents, cattle, primates) and to establish consistently the capacity of vaccination to reduce female worm fecundity and egg viability through the production of neutralizing antibodies (IgA and IgG). Following promising preclinical studies, clinical trials (phase I and II) have been undertaken using Schistosoma haematobium GST, Sh28GST. High titers of neutralizing antibodies were produced (IgG3 and IgA) together with Th2 cytokines, consistently with the concepts developed from experimental models. With these results we are on the way towards a feasible approach of vaccine development against a major human parasitic disease.

Abstract
Immune responses are controlled by a combination of positive and negative cellular signals. Effector cells in the immune system express inhibitory receptors that serve to limit effector cell expansion and to protect the host from autoreactivity. gp49B is a receptor of unknown function that is expressed on activated mast cells and natural killer (NK) cells and whose cytoplasmic tail endows it with inhibitory potential. To gain insight into the function of gp49B in mice, we disrupted the gp49B gene by homologous recombination. gp49B(0) mice were born at expected ratios, were healthy and fertile, and displayed normal long-term survival rates. gp49B(0) mice showed no defect in NK or mast cell development. Furthermore, NK and mast cells from the gp49B(0) mice showed activation properties in vitro similar to those of cells isolated from wild-type mice. Therefore, gp49B is not critical for the development, expansion, and maturation of mast cells and NK cells in vivo. The healthy status of gp49B(0) mice makes them suitable for testing the role of gp49B in immune responses to infectious agents.

Abstract
Besides its crucial role in type I hypersensitivity reactions, IgE is involved in anti-parasite immunity. This role has been clearly demonstrated in both human and rat schistosomiasis, but remains controversial in the mouse. Since the cellular distribution of the high affinity IgE receptor, Fc epsilon RI, differs in humans and mice, it might explain the differences in effector function of IgE between the two species. In humans, eosinophils and macrophages induce IgE-dependent cytotoxicity toward Schistosoma mansoni larvae, which involves Fc epsilon RI in the case of eosinophils. In the present study, we have investigated the expression and function of Fc epsilon RI in rat eosinophils and macrophages. We demonstrate, by flow cytometry, fluorescence microscopy, and western blot analysis, that in rats, as in humans, a functional alpha gamma 2 trimeric Fc epsilon RI is expressed on eosinophils and macrophages. We also show that these two cell types can induce IgE-mediated, Fc epsilon RI-dependent cellular cytotoxicity toward schistosomula. These results thus provide a molecular basis for the differences observed between rat and mouse regarding IgE-mediated anti-parasite immunity.

Abstract
A role for the Fc receptor beta chain (FcRbeta) in the pathogenesis of allergy has been suggested by genetic studies. FcRbeta is a subunit common to the high-affinity IgE (FcepsilonRI) and low-affinity IgG (FcgammaRIII) receptors, both of which contribute to the initiation of allergic reactions. Current in vitro data suggest that FcRbeta can function as either a positive or negative regulator, leaving a mechanistic explanation for its association with the development of atopy unclear. To address this controversy, we have generated novel mouse models relevant to human Fc receptor function. Analysis of FcepsilonRI- and FcgammaRIII-dependent responses in these mice provides unequivocal genetic evidence that FcRbeta functions as an amplifier of early and late mast cell responses and, remarkably, in vivo anaphylactic responses.

Abstract
The IgE/Fc epsilonRI interaction is postulated to play an important role in resistance to helminths both at the level of anti-parasitic effector cell function and in the initiation of Th2 responses through IL-4 produced by Fc epsilonRI+ non-B, non-T (NBNT) cells. To formally evaluate the role of IgE/Fc epsilonRI signaling in the host response to helminths we studied Schistosoma mansoni infection in Fc epsilonRI knockout (KO) mice. Infected wild-type (wt) and KO animals showed comparable adult worm and tissue egg burdens, arguing against a role for Fc epsilonRI interactions in host resistance. Significantly, NBNT cells from infected KO, in contrast to wt animals, did not secrete IL-4 when stimulated with anti-IgE Ab or soluble parasite Ag. Nevertheless, serum IgE levels and Th2 cytokine production profiles were comparable in both strains of mice, demonstrating that the Ag-dependent stimulation of IL-4 secretion by NBNT cells is not essential for helminth-induced Th2 differentiation. However, when stimulated with low Ag doses, splenocytes from infected Fc epsilonRI-deficient mice produced less IL-4 in vitro than similar cultures from infected wt animals, an effect attributable to their defective NBNT cell function. Moreover, infected KO mice showed enhanced egg granuloma formation and hepatic fibrosis, revealing that the IgE/Fc epsilonRI interaction, while not essential for Th2 response development or resistance to primary infection, plays a significant role in down-regulating host pathology.

Abstract
We attempted to elicit active anaphylaxis to ovalbumin, or passive IgE- or IgG1-dependent anaphylaxis, in mice lacking either the Fc epsilonRI alpha chain or the FcR gamma chain common to Fc epsilonRI and Fc gammaRI/III, or in mice lacking mast cells (KitW/ KitW-v mice), and compared the responses to those in the corresponding wild-type mice. We found that the FcR gamma chain is required for the death, as well as for most of the pathophysiological changes, associated with active anaphylaxis or IgE- or IgG1-dependent passive anaphylaxis. Moreover, some of the physiological changes associated with either active, or IgG1-dependent passive, anaphylactic responses were significantly greater in Fc epsilonRI alpha chain -/- mice than in the corresponding normal mice. Finally, while both KitW/KitW-v and congenic +/+ mice exhibited fatal active anaphylaxis, mast cell-deficient mice exhibited weaker physiological responses than the corresponding wild-type mice in both active and IgG1-dependent passive systemic anaphylaxis. Our findings strongly suggest that while IgE antibodies and Fc epsilonRI may influence the intensity and/or kinetics of some of the pathophysiological changes associated with active anaphylaxis in the mouse, the mortality associated with this response can be mediated largely by IgG1 antibodies and Fc gammaRIII.

Abstract
In mouse mast cells, both Fc epsilonRI and Fc gammaRIII are alpha beta gamma2 tetrameric complexes in which different alpha chains confer IgE or IgG ligand recognition while the signaling FcR beta and gamma chains are identical. We used primarily noninvasive techniques (changes in body temperature, dye extravasation) to assess systemic anaphylactic responses in nonanesthetized wild-type, Fc epsilonRI alpha chain -/- and FcR gamma chain -/- mice. We confirm that systemic anaphylaxis in mice can be mediated largely through IgG1 and Fc gammaRIII and we provide direct evidence that these responses reflect activation of Fc gammaRIII rather than Fc gammaRI. Furthermore, we show that Fc gammaRIII-dependent responses are more intense in normal than in congenic mast cell-deficient KitW/KitW-v mice, indicating that Fc gammaRIII responses have mast cell-dependent and -independent components. Finally, we demonstrate that the upregulation of cell surface expression of Fc gammaRIII seen in Fc epsilonRI alpha chain -/- mice corresponds to an increased association of Fc gammaRIII alpha chains with FcR beta and gamma chains and is associated with enhanced Fc gammaRIII-dependent mast cell degranulation and systemic anaphylactic responses. Therefore, the phenotype of the Fc epsilonRI alpha chain -/- mice suggests that expression of Fc epsilonRI and Fc gammaRIII is limited by availability of the FcR beta and gamma chains and that, in normal mice, changes in the expression of one receptor (Fc epsilonRI) may influence the expression of functional responses dependent on the other (Fc gammaRIII).

Abstract
The objective of this study was to determine the effects of pituitary hormones (luteinizing hormone [LH], follicle-stimulating hormone [FSH], growth hormone [GH], and prolactin [PRL]) on interstitial cell proliferation and differentiation in the testis of immature hypophysectomized rats. Macrophages, Leydig cells, precursor mesenchymal cells, endothelial lymphatic cells, and myoid cells were studied. Our experimental approach was aimed at determining whether changes in a cellular subpopulation observed after pituitary hormone treatments were the result of division of existing cells in the population, of differentiation of interstitial precursor cells, or both. In this context, it must be stressed that our data reflected the effects of hormones to prevent the decline of cells due to hypophysectomy rather than their recovery. Macrophage proliferation was taken into account because macrophages closely resemble Leydig cells and are known to proliferate after hormonal treatment. A double-labeling procedure (acid phosphatase and anti-bromodeoxyuridine [anti-BUdR]) revealed that LH, FSH, and PRL increased the number of testicular macrophages 105-, 104-, and 103-fold, respectively, in hypophysectomized rats compared to hypophysectomized control animals. BUdR incorporation in testicular macrophages was greater after PRL treatment than after LH and FSH supplementation. In contrast, we were unable to demonstrate any effect of rat GH on the macrophage population. Light microscopic analysis of plastic embedded sections of treated rat testis revealed that LH increased the numbers of Leydig, precursor mesenchymal, and myoid cells 6-, 4-, and 1.3-fold, respectively. LH also stimulated BUdR incorporation into all interstitial cell types. PRL administration increased both the number of Leydig and precursor mesenchymal cells (each 3-fold) but decreased the number of endothelial lymphatic cells (1.5-fold) when compared to the control animals. In contrast, FSH did not increase the number and proliferation of Leydig cells but exerted a slight proliferative effect on the other interstitial cell populations. In GH-treated rats, the number of precursor mesenchymal cells increased two fold above the control rats. GH also exerted slight proliferative effects on both precursor mesenchymal and myoid cells. Immunohistochemical studies of steroidogenic enzymes in the testicular interstitium of treated rats demonstrated the presence of steroidogenic enzymes, not only in Leydig and precursor mesenchymal cells, but also in some (1%-2%) endothelial lymphatic cells and myoid cells. This may indicate that both of these cell types are also constitutively equipped to perform steroidogenesis or that they are precursor cells undergoing differentiation. Taken together, changes in the number of Leydig cells in our animal model appeared more likely to be dependent on the transformation of precursor cells than on division of preexisting mature Leydig cells.

Abstract
Abstract
Mast cells and basophils, which are activated by IgE and allergens through the high affinity IgE receptor (Fc epsilon RI), play a prominent role in anaphylaxis in the mouse. Mice deficient in this receptor become resistant to passive anaphylaxis. As a first step in developing an in vivo model that more closely mimics the IgE-mediated responses in man, we used a combination of transgenic and embryonic stem cell technology to generate a mouse line in which the murine Fc epsilon RI alpha-chain has been replaced with its human homologue. We demonstrate here that these mice express a tetrameric high affinity IgE receptor, in which the human alpha-chain associates with the murine beta- and gamma-chains, and that upon triggering with relevant Ag, this receptor mediates the initiation of the expected intracellular events. In addition, we show that the human alpha-chain restores an anaphylactic response to the nonresponsive alpha-deficient parental mouse line. This "humanized" mouse represents a potentially important model system, not only for studying the role of IgE in human immune responses, but also for testing potential therapeutic reagents that can interfere with responses mediated through the human Fc epsilon RI receptor.

Abstract
Mast cells and basophils, which are activated by immunoglobulin E (IgE) and allergen, play a prominent role in anaphylaxis. However, they express at least three types of IgE receptor, including the high affinity IgE receptor (Fc epsilon RI). The relative contribution of these IgE receptors, and possibly other receptors such as Fc epsilon RII/CD23 and Mac-2, to the genesis of in vivo anaphylaxis is still unclear. To address this question, we have generated Fc epsilon RI-deficient mice. These mice appear normal and express a normal number of mast cells, but they are resistant to cutaneous and systemic anaphylaxis. These data demonstrate that Fc epsilon RI is necessary for the initiation of IgE-dependent anaphylactic reactions. Therefore, interfering with its function should be an effective means of treating allergy, regardless of the allergen specificity.

Abstract
Benign prostatic hyperplasia (BPH) is so common in elderly men that the development of adenomatous nodules in this organ can be seen as a normal age-dependent process. In this work, we used Northern blotting to compare the levels of androgen, estrogen, and insulin-like growth factor-I (IGF-I) receptor in young (age range, 23-33; n = 3), old normal (age range, 52-80; n = 3), and BPH-affected subjects (age range, 66-87; n = 15). We have also investigated in these groups the expression of genes coding for the two 5 alpha-reductases (types I and II), aromatase, IGF-I, and IGF-II. Our results show significantly increased levels of IGF mRNA in old healthy and BPH-affected subjects; the respective rises for IGF-I, IGF-II, and IGF-I receptor mRNAs were 3.0-, 2.9-, and 1.5-fold (BPH) and 2.7-, 2.4-, and 1.8-fold (old normal controls). For estrogen receptor, androgen receptor, and type I and II 5 alpha-reductase mRNAs, a marked but opposite effect was observed in adenomatous tissues only; the respective levels were 2.2-, 1.8-, 3.9-, and 1.7-fold lower than those in young adult subjects, whereas no significant differences were recorded between the two normal groups. Morphometric analysis of each tissue specimen confirmed the significantly lower epithelium/stroma ratio in adenomas compared to young or old healthy tissues. Together, these observations suggest that prostatic adenomas may result from at least two conjugate processes: one characterized by a drop in the mRNA levels of steroid hormone receptors, which might be associated with a lower epithelium/stroma ratio, and another characterized by normal aging phenomena, of which the increased production of IGFs and IGF-I receptor transcripts could be biochemical markers.

In this study we investigated the involvement of several different pituitary hormones on rat prostate development. 22-day-old Wistar rats, hypophysectomized (hypox) at 19 days of age were supplemented with highly purified human prolactin (hPRL), human luteinizing hormone (hLH), porcine follicle-stimulating hormone (pFSH), and bovine growth hormone (bGH) or with saline. Quantitative analysis of RNAs shows that treatment with either PRL or GH increases significantly steady-state mRNAs levels of the following genes in the prostate: androgen receptor (AR) (respectively 3.5- and 4.8-fold above hypox controls), IGF-I (5- and 2.7-fold), and IGF-I receptor (2.9- and 2.3-fold). LH and FSH, by contrast, have negative effects on these parameters. To test whether the enhancing effect of PRL and GH on AR-mRNA abundance was followed by increased content in the protein itself, binding assays were performed with the androgen agonist [3H]R1881 (131 and 153 fmol/mg protein while hypox controls contained 110 fmol/mg protein). In addition to the well-documented presence of prolactin receptors in prostatic tissues, we have further demonstrated, by means of nuclease S1 protection assays plus dot- and Northern-blot analyses, that a GH receptor mRNA is produced in the immature rat prostate. Moreover, we observed not only strong lactogenic but also purely somatogenic binding to be occurring in the immature prostates. Finally, we have studied IGF-I mRNA content in separated epithelial/stromal cell fractions and have concluded that IGF-I expression is principally located in the prostatic stroma. Taken together, these results suggest that PRL and GH are involved in regulating AR synthesis, at least partially by direct action on the organ. In this context IGF-I appears as a paracrine factor playing a role in epithelium/stroma interactions during prostatic development.

Abstract
IGF-I and II genes expression has been localized by in situ hybridization in testis and epididymis of immature hypophysectomized rats treated in vivo with either pFSH, hLH, bGH, hPRL or with saline. IGF-I mRNA expression was found in both Sertoli and Leydig cells after treatment with either FSH or LH. IGF-I mRNA was highly expressed in germ cells after FSH stimulation and to a lesser extent after GH or LH treatments. However, its expression was very low in hypophysectomized control or PRL treated rats. IGF-I mRNA was also expressed in stromal cells of epididymis after LH treatment and to a lesser extent after GH stimulation. In contrast, IGF-II mRNA expression was detected in all testicular cell types whatever the hormonal treatment (FSH, LH, GH, PRL). For each hormonal treatment testicular sections were examined after immunohistochemical staining with specific antisera against IGF-I and IGF-II. Both in situ hybridization and immunohistochemical data were examined in order to determine the testicular sites of synthesis of IGF-I and IGF-II.

Abstract
We have studied dose-dependent effects of highly purified human PRL (39 IU/mg) on the testis of immature (22-day-old) hypophysectomized rats daily supplemented for 7 days with 2, 10, or 30 micrograms hormone. Dose-dependent stimulation was observed for all parameters: testis weight (1.6- and 2-fold above control for 10 and 30 micrograms PRL), basal and hCG-stimulated testosterone (14- and 21-fold), intratesticular testosterone (7- and 21-fold) and estradiol (1.2- and 1.5-fold), LH receptor concentration (1.8- and 2.5-fold), in vitro pregnenolone production by cholesterol side-chain cleavage enzyme (3-, 5- and 7-fold), and aromatase activity (2.1- and 2.4-fold). The number of Leydig cells exhibiting immunoreactivity toward anti-P450scc, anti-P450(17 alpha), and anti-3 beta-hydroxysteroid dehydrogenase antibodies also underwent a dose-dependent increase (under conditions revealing many immunopositive cells in hypox control animals). The respective increases were 8- to 14-fold for anti-P450scc and P450(17 alpha) and 1.5- to 2-fold for anti-3 beta-hydroxysteroid dehydrogenase. The number of germ cells and the percentage of tubular sections containing late pachytene spermatocytes as most advanced stages of spermatogenesis were subject to similar dose-dependent effects. These results suggest that during puberty PRL stimulates testicular function by promoting multiplication and differentiation of Leydig cells (acting at various steps of steroidogenesis and on tissue responsiveness to LH) and germ cells.

Abstract
In this study we have compared the effects of the homologous rat growth hormone with its human and bovine counterparts on the testicular development of immature hypophysectomized rats, after 7 days of treatment. Each hormone increased (12- to 13-fold) the body weight gain and IGF-I blood level (12- to 16-fold). Human GH increased testis weight (1.3-fold) the pregnenolone production (4-fold), the LH dependent steroidogenesis (7-fold), the aromatase activity (5-fold), the concentration of LH receptors (1.6-fold) and spermatogenesis. Bovine and rat growth hormones had marked effects only on pregnenolone production (2- to 3-fold). Incorporation of 5-bromodeoxyuridine in testicular cells after hGH treatment was positive (0.47 per 100 cells), an effect which was 2-fold higher than those produced by bovine and rat GHs (0.25 per 100 cells). These results have led us to conclude that the in vivo action of rat growth hormone on rat testis is comparable to bovine GH and thus might be considered as purely somatogenic. In addition to the known effects on growth promotion, rat GH affected the rate limiting step of steroidogenesis and the Leydig cell multiplication.

Abstract
A monoclonal anti-bromodeoxyuridine antibody conjugated to fluorescein was used to detect the chloroplast nucleoids after specific incorporation of bromodeoxyuridine (BUdR) into the chloroplast DNA of Chlamydomonas reinhardtii. The incorporation of BUdR was enhanced by simultaneous treatment with fluorodeoxyuridine (FUdR). The method was applied to analyze the fate of chloroplast DNA in zygotes resulting from mating between BUdR-treated gametes (mt+ or mt-) and untreated gametes of opposite mating-type. In crosses between wild-type strains, the nucleoids of mt+ origin remained in the large majority of zygotes whereas those of mt- origin most often disappeared within the first hours following copulation. In crosses of the type mat-3 mt+ x wild-type mt- (the mat-3 mutation permits a high transmission of chloroplast genes from the mt- parent), the nucleoids of mt- origin were generally not eliminated which indicates that the mat-3 mutation prevents the selective destruction of paternal chloroplast DNA in the zygote.

Abstract
Since insulin-like growth factors I (IGF-I) and II (IGF-II) appeared involved in paracrine or autocrine regulation of both cell multiplication and differentiation of the rat testis, we have investigated the pituitary hormonal dependence of IGF-I and IGF-II mRNA production in the testis of immature hypophysectomized rats (22 days old) supplemented with highly purified FSH, LH, GH or PRL. Our data show that testicular expression of IGF-I mRNA as measured by dot-blot hybridization, is increased by LH, FSH or GH treatments of 7-, 6-, and 4-fold, respectively, above controls. Intensity of the signal was 3-fold lower after PRL treatment than in hypophysectomized control rats. On the contrary, IGF-II mRNA expression, was found low in the immature hypophysectomized rat testis and unmodified by any hormonal treatment. In contrast to the increase of IGF-I expression in the testis no significant change in the IGF-I plasma concentration was observed after LH or FSH supplementation. GH treatment, as expected, increased 4-fold the IGF-I plasma concentration of the experimental animals. Since we have previously shown that LH, FSH, and GH exhibit selective cell multiplication and differentiation in the testis of our animal model, it is proposed that testicular IGF-I expression could be the tissue response to pituitary hormone in these phenomena.

Abstract
A non radioactive method for probing RNA or DNA on dot and Northern blots using a synthetic oligonucleotide with bromodeoxyuridine free ends is described. The present experiment was carried out with human testis and placental RNA's. The probe was the 21 base long sequence coding for the amino acids 18 to 24 of the insulin-like growth factor I (IGF-I) with two bromodeoxyuridine dinucleotides added at the 5' and 3' ends. The probe was detected with a monoclonal antibody against bromodeoxyuridine and immunogold silver staining (IGSS). Our method was compared to the peroxydase (HRP) revelation of the same probe. The results obtained show a lower background with IGSS than with HRP revelation. A sensitivity similar to that of 32P labelling was found with the advantages of an increase in the rapidity of the procedure (24 hours instead of 9 days exposure) and the absence of handling radioactive substances. Moreover, as the monoclonal antibody against BrdU detects single stranded DNA only, the use of BrdU free ends-labelled oligonucleotide allows the development of the revelation procedure without any previous denaturation of the hybrid. This particular point is an indisputable advantage for detecting hybridization in situ.

Abstract
For the first time a monoclonal antibody against 5-bromodeoxyuridine was used to detect cell proliferation in pig testis and intestine sections. The influence of several parameters such as mode of injection, addition of thymidine biosynthesis inhibitor, tissue fixation, hydrolysis and revelation was examined. The technique of choice consisted in intravenously injecting the animals with 50 mg/kg BUdR added to 10 mg/kg FUdR 2 h before tissue collection and Bouin fixation; hydrolysis of sections was performed by HC1 4N: Ethanol 70 degrees (1:1 v/v); revelation of BUdR was made by a secondary antibody linked to colloidal gold particles, followed by a silver enhancement step. The data were superior when compared to those obtained by direct immunofluorescence and by the PAP technique. The described method is convenient and sensitive, provides an intense nuclear labelling without background and allows simultaneous examination of histology. The advantages over the technique using tritiated thymidine are particularly obvious when fast screening of numerous samples is required or when new experimental protocols are developing.
