Abstract
Human CD4+EOMES+ T cells are heterogeneous and contain Th1-cells, Tr1-cells, and CD4+CTL. Tr1- cells and non-classical EOMES+ Th1-cells displayed, respectively, anti- and pro-inflammatory cytokine profiles, but both expressed granzyme-K, produced IFN-γ, and suppressed T-cell proliferation. Diffusion map suggested a progressive CD4+T-cell differentiation from naïve to cytotoxic cells and identified EOMES+Th1-cells as putative Tr1-cell precursors (pre-Tr1).

Abstract
IFNγ-producing ex-Th17 cells ['Th1/17'] were shown to play a key pathogenic role in experimental colitis and are abundant in the intestine. Here, we identified and characterised a novel, potentially colitogenic subset of Th17 cells in the intestine of patients with Crohn's disease [CD]. Human Th17 cells expressing CCR5 ['pTh17'] co-expressed T-bet and RORC/γt and produced very high levels of IL-17, together with IFN-γ. They had a gene signature of Th17 effector cells and were distinct from established Th1/17 cells. pTh17 cells, but not Th1/17 cells, were associated with intestinal inflammation in CD, and decreased upon successful anti-TNF therapy with infliximab. Conventional CCR5[-]Th17 cells differentiated to pTh17 cells with IL-23 in vitro. Moreover, anti-IL-23 therapy with risankizumab strongly reduced pTh17 cells in the intestine. Importantly, intestinal pTh17 cells were selectively activated by adherent-invasive Escherichia coli [AIEC], but not by a commensal/probiotic E. coli strain. AIEC induced high levels of IL-23 and RANTES from dendritic cells [DC]. Intestinal CCR5+Th1/17 cells responded instead to cytomegalovirus and were reduced in ulcerative colitis [UC], suggesting an unexpected protective role. In conclusion, we identified an IL-23-inducible subset of human intestinal Th17 cells. pTh17 cells produced high levels of pro-inflammatory cytokines, were selectively associated with intestinal inflammation in CD, and responded to CD-associated AIEC, suggesting a key colitogenic role.

Abstract
PURPOSE To assess the efficacy of lung low-dose radiotherapy (LD-RT) in the treatment of patients with COVID-19 pneumonia. MATERIALS AND METHODS Ambispective study with two cohorts to compare treatment with standard of care (SoC) plus a single dose of 0.5 Gy to the whole thorax (experimental prospective cohort) with SoC alone (control retrospective cohort) for patients with COVID-19 pneumonia not candidates for admission to the intensive care unit (ICU) for mechanical ventilation. RESULTS Fifty patients treated with LD-RT were compared with 50 matched controls. Mean age was 85 years in both groups. An increase in arterial oxygen partial pressure (PaO2)/fraction of inspired oxygen (PAFI) in the experimental LD-RT-treated group compared to the control group could not be found at 48 h after LD-RT, which was the primary endpoint of the study. However, PAFI values significantly improved after 1 month (473 vs. 302 mm Hg; p < 0.0001). Pulse oxymetric saturation/fraction of inspired oxygen (SAFI) values were also significantly higher in LD-RT-treated patients than in control patients at 1 week (405 vs. 334 mm Hg; p = 0.0157) and 1 month after LD-RT (462 vs. 326 mm Hg; p < 0.0001). All other timepoint measurements of the respiratory parameters were similar across groups. Patients in the experimental group were discharged from the hospital significantly earlier (23 vs. 31 days; p = 0.047). Fifteen and 26 patients died due to COVID-19 pneumonia in the experimental and control cohorts, respectively (30% vs. 48%; p = 0.1). LD-RT was associated with a decreased odds ratio (OR) for 1‑month COVID-19 mortality (OR = 0.302 [0.106-0.859]; p = 0.025) when adjusted for potentially confounding factors. Overall survival was significantly prolonged in the LD-RT group compared to the control group (log-rank p = 0.027). No adverse events related to radiation treatment were observed. CONCLUSION Treatment of frail patients with COVID-19 pneumonia with SoC plus single-dose LD-RT of 0.5 Gy improved respiratory parameters, reduced the period of hospitalization, decreased the rate of 1‑month mortality, and prolonged actuarial overall survival compared to SoC alone.

Abstract
Metastatic brain disease (MBD) has seen major advances in clinical management, focal radiation therapy approaches and knowledge of biological factors leading to improved prognosis. Extracellular vesicles (EVs) have been found to play a role in tumor cross-talk with the target organ, contributing to the formation of a premetastatic niche. Human lung and breast cancer cell lines were characterized for adhesion molecule expression and used to evaluate their migration ability in an in vitro model. Conditioned culture media and isolated EVs, characterized by super resolution and electron microscopy, were tested to evaluate their pro-apoptotic properties on human umbilical vein endothelial cells (HUVECs) and human cerebral microvascular endothelial cells (HCMEC/D3) by annexin V binding assay. Our data showed a direct correlation between expression of ICAM1, ICAM2, β3-integrin and α2-integrin and the ability to firmly adhere to the blood-brain barrier (BBB) model, whereas the same molecules were down-regulated at a later step. Extracellular vesicles released by tumor cell lines were shown to be able to induce apoptosis in HUVEC while brain endothelial cells showed to be more resistant.

Abstract
Type 1 regulatory (Tr1) T cells are currently defined all T cells with regulatory functions that lack FOXP3 expression and produce IL-10. Tr1 cells are heterogeneous, and the different reported properties of Tr1-cell populations have caused some confusion in the field. Moreover, understanding the role of Tr1 cells in immune-mediated diseases has been hampered by the lack of a lineage-defining transcription factor. Several independent studies indicated recently that the transcription factor Eomesodermin (EOMES) could act as a lineage-defining transcription factor in a population of IL-10 and IFN-γ co-producing Tr1-like cells, since EOMES directly induces IFN-γ and cytotoxicity, enhances IL-10, and antagonizes alternative T-cell fates. Here, we review the known properties of EOMES+ Tr1-like cells. They share several key characteristics with other Tr1 cells (i.e., "Tr1-like"), namely high IL-10 production, cytotoxicity, and suppressive capabilities. Notably, they also share some features with FOXP3+ Tregs, like downregulation of IL-7R and CD40L. In addition, they possess several unique, EOMES-dependent features, that is, expression of GzmK and IFN-γ, and downregulation of type-17 cytokines. Published evidence indicates that EOMES+ Tr1-like cells play key roles in graft-versus-host disease, colitis, systemic autoimmunity and in tumors. Thus, EOMES+ Tr1-like cells are key players of the adaptive immune system that are involved in several different immune-mediated diseases.

Abstract
Intracranial aneurysms (IAs) are very rare in children, and the characteristics of the T-cells in the IA wall are largely unknown. A comatose 7-years-old child was admitted to our center because of a subarachnoid hemorrhage due to a ruptured giant aneurysm of the right middle cerebral artery. Two days after the aneurysm clipping the patient was fully awake with left hemiparesis. T-cells from the IA wall and from peripheral blood of this patient were analyzed by multi-dimensional flow cytometry. Unbiased analysis, based on the use of FlowSOM clustering and dimensionality reduction technique UMAP, indicated that there was virtually no overlap between circulating and tissue-infiltrating T-cells. Thus, naïve T-cells and canonical memory T-cells were largely restricted to peripheral blood, while CD4-CD8-T-cells were strongly enriched in the IA wall. The unique CD4+, CD8+ and CD4-CD8-T-cell clusters from the IA wall expressed high levels of CCR5, Granzyme B and CD69, displaying thus characteristics of cytotoxic and tissue-resident effector cells. Low Ki67 expression indicated that they were nevertheless in a resting state. Among regulatory T-cell subsets, Eomes+Tr1-like cells were strongly enriched in the IA wall. Finally, analysis of cytokine producing capacities unveiled that the IA wall contained poly-functional T-cells, which expressed predominantly IFN-γ, TNF and IL-2. CD4+T-cells co-expressed also CD40L, and produced some IL-17, GM-CSF and IL-10. This report provides to our knowledge the first detailed characterization of the human T-cell compartment in the IA wall.

Abstract
BACKGROUND Lymphangioleiomyomatosis (LAM) and pulmonary Langerhans Cell Histiocytosis (PLCH) are cystic lung diseases in which a neoplastic cell is believed to be responsible for disease pathogenesis. The neoplastic LAM cell has mutations in the Tuberous Sclerosis Complex (TSC) genes, TSC1 or TSC2, whereas the neoplastic PLCH cell may have mutations in several genes, e.g., BRAF, NRAS, MAP2K1. These mutations are not specific for PLCH and they have been described in multiple cancers. TSC1 or TSC2 mutations and loss of heterozygosity (LOH) have also been described in cancers. RESEARCH QUESTION Is TSC2 LOH specific to LAM or is it also found in PLCH too? STUDY DESIGN We recruited LAM patients (53) and Healthy Volunteers (22) and compared the presence of cells with TSC2 LOH with PLCH patients (12). Blood and urine samples were collected for analysis. METHODS Fluorescence-activated cell sorting (FACS) was used to identify subpopulations of cells from blood and urine samples. We isolated CD45-CD235a-, CD45-CD235a+, CD45+CD235a- cells from blood following density gradient separation. Cells were screened for TSC2 LOH at 5 microsatellites markers (i.e., kg8, D16S3395, D16S3024, D16S521, D16S291). We obtained four cell subpopulations from urine (i.e., CD44v6+CD9+; CD44v6+CD9-; CD44v6-CD9+; CD44v6-CD9). RESULTS Using FACS, cells were isolated from blood and urine from PLCH patients that showed TSC2 LOH. Healthy volunteers did not have cells with TSC2 LOH. As a control, cells isolated from blood and urine from LAM patients gave results similar to those reported previously. These data show that TSC2 LOH is found in patients with cystic lung diseases with potential neoplastic characteristics, as well as in patients with cancer. INTERPRETATION The presence of TSC2 LOH in circulating cells is not specific for LAM. The data suggest that chromosomal abnormalities affecting the TSC2 gene are found in other diseases associated with cells having cancer-like neoplastic cells.

Abstract
Ex vivo gene expression and miRNA profiling of Eomes+ Tr1-like cells suggested that they represent a differentiation stage that is intermediate between Th1-cells and cytotoxic CD4+ T-cells. Several microRNAs were downregulated in Eomes+ Tr1-like cells that might inhibit Tr1-cell differentiation. In particular, miR-92a targeted Eomes, while miR-125a inhibited IFN-g and IL-10R expression.

Abstract
Purpose To evaluate the efficacy and safety of lung low-dose radiation therapy (LD-RT) for pneumonia in patients with coronavirus disease 2019 (COVID-19). Materials and methods Inclusion criteria comprised patients with COVID-19-related moderate–severe pneumonia warranting hospitalization with supplemental O2 and not candidates for admission to the intensive care unit because of comorbidities or general status. All patients received single lung dose of 0.5 Gy. Respiratory and systemic inflammatory parameters were evaluated before irradiation, at 24 h and 1 week after LD-RT. Primary endpoint was increased in the ratio of arterial oxygen partial pressure (PaO2) or the pulse oximetry saturation (SpO2) to fractional inspired oxygen (FiO2) ratio of at least 20% at 24 h with respect to the preirradiation value. Results Between June and November 2020, 36 patients with COVID-19 pneumonia and a mean age of 84 years were enrolled. Seventeen were women and 19 were men and all of them had comorbidities. All patients had bilateral pulmonary infiltrates on chest X‑ray. All patients received dexamethasone treatment. Mean SpO2 pretreatment value was 94.28% and the SpO2/FiO2 ratio varied from 255 mm Hg to 283 mm Hg at 24 h and to 381 mm Hg at 1 week, respectively. In those who survived (23/36, 64%), a significant improvement was observed in the percentage of lung involvement in the CT scan at 1 week after LD-RT. No adverse effects related to radiation treatment have been reported. Conclusions LD-RT appears to be a feasible and safe option in a population with COVID-19 bilateral interstitial pneumonia in the presence of significant comorbidities.

Abstract
BACKGROUND Two-stage revision for periprosthetic knee infection is challenging in cases of massive bone loss and instability. The present study aims to describe our experience with an alternative technique of reinforced cement spacer, usually necessary in these situations, focusing on its advantages and clinical results. METHODS We retrospectively identified all patients who underwent a two-stage revision for periprosthetic knee infection using two intramedullary Küntscher nails as reinforcement from January 2010 to September 2018. From each medical record, we extracted the type of explanted prosthesis, isolated micro-organism, number of cement spacers before index procedure (and related episodes of spacer dislocation) and final treatment. RESULTS Twelve patients were identified, mean age of 64.0 years (range 39-85). In four of them, the reinforced spacer was used twice for persistent infection, with a total of 16 procedures performed and no cases of dislocation. Ten patients were finally treated with reimplantation or arthrodesis with intramedullary nails, whereas an above-knee amputation was necessary for two patients. Infection was eradicated in 10 patients out of 12 (83%) at a mean follow up of 34.3 months (range 10-62). CONCLUSIONS This technique is an effective alternative to traditional spacers in cases of massive bone loss, producing a mechanically stable joint and preserving adequate tissue tensions. The construct is technically easy to perform and, not less importantly, to remove during stage 2. Further studies, with larger groups, are necessary to determine its validity.

Abstract
Glioblastoma multiforme (GBM) is considered the most malignant form of primary brain tumor. Despite multimodal treatment, prognosis remains poor. Ketogenic diet (KD) has been suggested for the treatment of GBM. In this study, the syngenic, orthotopic GL261 mouse glioma model was used to evaluate the effects of KD on the metabolic responses of the tumor using 7T magnetic resonance imaging/spectroscopy. GL261 cells were injected into the caudate nucleus of mice. Following implantation, animals were fed with standard chow or underwent a KD. 18 days after initiating the diet, mice fed with KD displayed significantly higher plasmatic levels of ketone bodies and survived longer than those fed with the standard diet. Decreased concentrations of gamma-aminobutyric acid, N-Acetyl-Aspartate and N-acetylaspartylglutamate were found in tumor tissue after 9 days into the KD, while a huge increase in beta-hydroxybutyrate (bHB) was detected in tumor tissue as compared to normal brain. The accumulation of bHB in the tumor tissue in mice undergoing the KD, may suggest either elevated uptake/release of bHB by tumor cells, or the inability of tumor cells in this context to use it for mitochondrial metabolism.

Abstract
Background:IL-10 plays a key role in systemic lupus erythematosus (SLE) pathogenesis, promoting B-cell response. IL10 is mainly secreted by regulatory T-cells, but follicular helper T-cells (TFH), also produce it. We previously identified a subset of CCR6+IL-7R+T-cells in human tonsils providing IL-10-dependent B-cell help. These CCR6+T-cells were able to produce IL-10, inducing IgG production.Objectives:to investigate a possible role of CD4+CCR6+IL7R+T-cells in SLE pathogenesis.Methods:37 patients fulfilling the ACR criteria for SLE have been included. Disease activity was assessed by 2k-SLEDAI. PBMC were analyzed by flow cytometry, using specific lineage markers. CCR6+IL7R+T-cells purified from total PBMC of SLE patients or healthy donors (HD) were co-cultured with autologous CD20+B-cells. IL-10, Il-17, total IgG and anti-dsDNA antibodies titers in patients serum and culture supernatants were assessed by ELISA. Embedded sections of lymph nodes from 8 SLE patients were analyzed by immunofluorescence (IF).Results:IL10 levels were significantly higher in SLE patients (Fig 1A). CD4+CCR6+IL7R+T-cells were significantly increased in SLE, in particular in those with higher disease activity and higher IL10 levels. CD4+CCR6+IL7R+T-cells levels associated with anti-dsDNA positivity. CCR6+IL7R+T-cells of SLE patients induced production of IgG and anti-dsDNA IgG (in anti-dsDNA + patients) from autologous B-cells, providing spontaneous help for autoantibody productionex vivo(Fig 1B-C). The IF study of lymph nodes of SLE patients showed that IL-10-producing CCR6+T-cells were highly abundant and co-localized with B-cells at follicle margins.Fig 1Conclusion:our study revealed a novel population of extra-follicular B-helper T-cells, which produce IL-10 and could play a prominent pathogenic role in SLE. Further studies will clarify if this potentially pathogenic cell population might represent a possible future therapeutic target.References:[1]Facciotti F. J Allergy Clin Immunol. 2016; Geginat J.

Abstract
Abstract
Glioblastoma multiforme is the most malignant subtype of brain tumor. Despite multimodal treatment (surgical resection and chemo/radiotherapy) the prognosis remains unsatisfactory. Based on the Warburg hypothesis, ketogenic diet (KD) has been suggested in the treatment of GBM. The syngenic, orthotopic GL261 mouse glioma model was used to evaluate the effects of KD on 7T magnetic resonance imaging/spectroscopy and metabolic response of the tumor to diet. Mice were injected with 10^5 GL261 cells into the caudate nucleus. Following implantation, animals were fed standard chow for five days then were randomly assigned to standard diet or ketogenic diet. 18 days after diet start, mice fed at KD displayed significantly higher plasmatic levels of ketone bodies. Mice fed with KD survived longer than those fed with standard diet (p< 0.05). Decreased concentrations of gamma-aminobutyric acid, N Acetyl Aspartate and N-acetylaspartylglutamate were found in tumor tissue after 9 days from the beginning of the KD diet while a huge increase in beta-hydroxybutyrate (bHB) was detected in tumor tissue as compared to normal brain. The addition of bHB at various concentrations to low-glucose culture medium did not significantly improve GL261 in vitro growth suggesting that this cell line has a limited ability to use bHB as a carbon source. The accumulation of bHB in the tumor tissue in KD fed mice, may suggest either elevated uptake of/release of bHB by tumor cells or inability of tumor cells in this context to use it in mitochondrial metabolism; the latter hypothesis is supported by the observation that GL261 cells did not display an increase in in vitro proliferation when exposed to bHB. The far less evident peak of bHB at MRI spectroscopy in the healthy brain tissue of KD fed mice, on the other hand suggests that normal brain is able to use bHB as energy source.

Abstract
Classification of morphological features in biological samples is usually performed by a trained eye but the increasing amount of available digital images calls for semi-automatic classification techniques. Here we explore this possibility in the context of acrosome morphological analysis during spermiogenesis. Our method combines feature extraction from three dimensional reconstruction of confocal images with principal component analysis and machine learning. The method could be particularly useful in cases where the amount of data does not allow for a direct inspection by trained eye.

Abstract
Background Epilepsy is a frequent symptom in patients with glioma. Although treatment with antiepileptic drugs is generally effective in controlling seizures, drug-resistant patients are not uncommon. Multidrug resistance proteins (MRPs) and P-gp are over-represented in brain tissue of patients with drug-resistant epilepsy, suggesting their involvement in the clearance of antiepileptic medications. In addition to their anticonvulsant action, some drugs have been documented for cytotoxic effects. Aim of this study was to evaluate possible in vitro cytotoxic effects of two new-generation antiepileptic drugs on a human glioma cell line U87MG. Methods Cytotoxicity of brivaracetam and lacosamide was tested on U87MG, SW1783 and T98G by MTS assay. Expression of chemoresistance molecules was evaluated using flow cytometry in U87MG and human umbilical vein endothelial cells (HUVECs). To investigate the putative anti-proliferative effect, apoptosis assay, microRNA expression profile and study of cell cycle were performed. Results Brivaracetam and lacosamide showed a dose-dependent cytotoxic and anti-migratory effects. Cytotoxicity was not related to apoptosis. The exposure of glioma cells to brivaracetam and lacosamide resulted in the modulation of several microRNAs; particularly, the effect of miR-195-5p modulation seemed to affect cell cycle, while miR-107 seemed to be implicated in the inhibition of cells migration. Moreover, brivaracetam and lacosamide treatment did not modulate the expression of chemoresistance-related molecules MRPs1-3-5, GSTπ, P-gp on U87MG and HUVECs. Conclusion Based on antineoplastic effect of brivaracetam and lacosamide on glioma cells, we assume that patients with glioma could benefit by the treatment with these two molecules, in addition to standard therapeutic options.

Abstract
Objectives To investigate if HDL cholesterol (HDL-c) could be a biomarker of the degree of severity according to prognostic prediction scores in community-acquired pneumonia (CAP) or the development of clinical complications such as pleural effusion. Methods We included in a retrospective study 107 patients admitted to the hospital that fulfilled diagnostic criteria for CAP between the 30th October 2011 and 1st September 2012. HDL-c levels at admission, CAP prognosis scores (PSI and CURB65) and clinical outcomes were recorded for the study. Results Basal HDL-c levels were not statistically different according to prognostics scores neither PSI nor CURB-65. Significantly lower levels of HDL-c were also associated to the development of septic shock and admission to the intensive care unit. HDL-c were inversely correlated with acute phase reactants CRP (r = −0.585, P < 0.001), ESR (r = −0.477, P < 0.001), and leukocytes cell count (r = −0.254, P < 0.009). Patients with pleural effusion showed significant lower levels of HDL-c [28.9 (15.5) mg/dl vs. 44.6 (21.1) mg/dl]; P = 0.007. HDL-c is a good predictor of the presence of pleural effusion in multivariate analyses and using ROC analyses [AUC = 0.712 (0.591–0.834), P = 0.006]. HDL-c levels of 10 mg/dl showed a sensitivity of 97.6 % and a specificity of 82.4 % for the presence of pleural effusion. Conclusion Monitoring HDL-c in CAP is an useful serum marker of acute phase response, clinical outcome and the presence of pleural effusion.

Abstract
Within species, populations differing by chromosomal rearrangements ("chromosomal races") may become reproductively isolated in association with reduced hybrid fertility due to meiotic aberrations. Speciation is also possible if hybridizing chromosomal races accumulate genetic differences because of reduced meiotic recombination in the heterozygous configuration in hybrids. Here, we examine recombination in pure races and hybrids within a model system for chromosomal speciation: the hybridization of the Poschiavo (CHPO) and Upper Valtellina (IUVA) chromosomal races of house mouse in Upper Valtellina, Italy. These races differ by Robertsonian fusions/whole-arm reciprocal translocations, such that hybrids produce a pentavalent meiotic configuration. We determined the number and position of the recombination points (using an antibody against the MutL homolog 1 [MLH1] protein) on synaptonemal complexes at pachytene in laboratory-reared CHPO, IUVA, and hybrid males, analyzing at least 112 spermatocytes per karyotypic group, up to a total of 534 spermatocytes. The mean ± standard deviation numbers of MLH1 foci per spermatocyte were 22.2 ± 3.2, 20.1 ± 2.9, 20.7 ± 2.3, and 21.9 ± 2.9 for CHPO, IUVA, CHPO × IUVA, and IUVA × CHPO, respectively. Altogether, 10,146 chromosome arms were examined, allowing multiple comparisons. Overall, recombination events were more frequently distal than proximal or interstitial. The average number of proximal MLH1 foci per chromosome arm decreased going from telocentric to metacentric bivalents to pentavalents (when present), which (together with other factors) influenced the average number of MLH1 foci per cell between CHPO, IUVA, and hybrid mice. The low frequency of proximal recombination in pentavalents of CHPO-IUVA hybrids may promote reproductive isolation between the CHPO and IUVA races, when coupled with reduced hybrid unfitness.

Abstract
The house mouse is characterised by highly variable chromosome number due to the presence of Robertsonian (Rb) chromosomes. During meiosis in Rb heterozygotes, intricated chromosomal figures are produced, and many unsynapsed regions are present during the first prophase, triggering a meiotic silencing of unsynapsed chromatin (MSUC) in a similar mode to the sex chromosome inactivation. The presence of unsynapsed chromosome regions is associated with impaired spermatogenesis. Interestingly, in male mice carrying multiple Rb trivalents, the frequency of germ cell death, defective tubules, and altered sperm morphology decreases during aging. Here, we studied whether synapsis of trivalent chromosomes and MSUC are involved in this improvement. By immunocytochemistry, we analysed the frequency of unsynapsed chromosomes and of those positive to γH2AX (a marker of MSUC) labelling in spermatocytes of 3-, 5- and 7-month-old Rb heterozygotes. With aging, we observed a decrease of the frequency of unsynapsed chromosomes, of spermatocytes bearing them and of trivalents carrying γH2AX-negative unsynapsed regions. Our quantitative results show that both synapsis and MSUC processes are better accomplished during male aging, partially accounting for the improvement of spermatogenesis.

Abstract
The protocol here described allows the analysis of gene expression in single specific mouse spermatogenetic cells. Germ cells were singularly isolated by microdissection of portions of seminiferous tubules classified, based on their transillumination pattern, into four distinct zones along their length. Single portions of a seminiferous tubule, corresponding to specific zones, were mechanically disaggregated into single cells that were (1) identified as spermatogonia, spermatocytes, round or elongated spermatids, (2) isolated using a micromanipulator, and (3) singularly transferred into a test tube for retro-transcription PCR analysis. On each single isolated cell, we have determined the quantitative profile of expression of Gapdh, an endogenous housekeeping gene known to be expressed throughout spermatogenesis. The protocol described allows an accurate analysis of the temporal and quantitative profile of gene expression throughout the whole male gamete differentiation process which so far has mainly been performed on enriched population of cells.

Abstract
The aim of this study was to determine whether the intrinsic mechanism of apoptosis is involved in the death of germ cells in Robertsonian (Rb) heterozygous adult male mice. Testes from 5-month-old Rb heterozygous CD1 x Milano II mice were obtained and compared with those from homozygous CD1 (2n=40) and Milano II (2n=24) mice. For histological evaluation of apoptosis, TUNEL labelling and immunohistochemistry were used to localise Bax and cytochrome c. Expression of calbindin D(28k) (CB), an anti-apoptotic molecule, was also analysed by immunohistochemistry and immunoblotting. Testicular ultrastructure was visualised by electron microscopy. Morphology and cell associations were abnormal in the Rb heterozygous seminiferous epithelium. An intense apoptotic process was observed in tubules at stage XII, mainly in metaphase spermatocytes. Metaphase spermatocytes also showed Bax and cytochrome c redistributions. Mitochondria relocated close to the paranuclear region of spermatocytes. CB was mainly expressed in metaphase spermatocytes, but also in pachytene spermatocytes, spermatids and Sertoli cells at stage XII. The co-localisation of CB and TUNEL labelling was very limited. Sixty per cent of metaphase spermatocytes were apoptotic and calbindin negative, while 40% were calbindin positive without signs of apoptosis. Ten per cent of the Bax- and cytochrome c-positive cells were also calbindin positive. These data suggest that apoptosis of the germ cells in heterozygous mice occurs, at least in part, through a mitochondrial-dependent mechanism. Calbindin overexpression might prevent or reduce the apoptosis of germ cells caused by Rb heterozygosity, which could partially explain the subfertility of these mice.

Abstract
Bentazon is a herbicide used to control many broadleaf weeds and sedges. Its use has improved rice production in paddy fields in Northern Italy, but as a negative consequence it is found in groundwater, the major source of drinking water. To determine whether low doses of bentazon affect spermatogenesis, it was dissolved in water at the concentration of 30 microg/L. Bentazon was administered through drinking water to: (1) adult mice for 100 days and (2) mice exposed in utero, during lactation and for 100 days after birth. The histopathological analysis of testes of treated animals showed that the frequency of defective tubules was comparable to that found in control groups. The cell associations of the 12 stages of the seminiferous epithelium were correct as well as the architecture of the epithelium. The spermatocytes/spermatids ratio was the same as in controls. However, the frequency of stages VII, IX and XII of the cycle of the seminiferous epithelium of adult mice and of stages I, III and VII of mice exposed in utero and for 100 days after birth was different when compared to that of control mice. Sperm number and morphology were not affected by the treatment. The potential genotoxic effects were evaluated on spermatozoa (Comet assay), in pachytene spermatocytes (analysis of the synaptonemal complex) and in bone marrow cells (frequency of micronuclei). None of these analyses evidenced genotoxic effects of bentazon. Although our results show that the administration of a low dose of bentazon does not impair spermatogenesis, we found alterations of the frequency of some stages of the cycle of the seminiferous epithelium in both experimental groups.
