Abstract
BACKGROUND Open Abdomen (OA) is gaining popularity in damage control surgery (DCS) but there is not an absolute prognostic score to identify patients that may benefit from it. Our study investigates the correlation between the clinical frailty scale score (CFSS) and postoperative morbidity and mortality in patients undergoing OA. METHODS Patients ≥65 yo undergoing OA in two referral centres between 2015 and 2020 were included and stratified according to CFSS in non-frail (NF), frail (F) and highly-frail (HF). The primary endpoint was 30-day mortality. Secondary endpoints were postoperative morbidity and 1- year survival. RESULTS One hundred and thirty-six patients were included: 35 NF (25.7%), 56 F (41.2%), 45 HF (33.1%). Average age 76.8. The 73.5% of cases were non-traumatic diseases with no difference in preoperative characteristics. 95 (71.4%) had one complication, 26 NF (74.3%), 34 F (63.2%), 35 HF (77.8%) (P=0.301) and 59.4% had a complication with a CD≥3, 57.1% NF, 56.6% F and 64.4 HF. The 30-day mortality was 32.4%, higher in HF (46.7%) and F (30.4%) compared to NF (17.1%, P=0.018). The Overall 1-year survival was 41% (SE ±4) with statistically significant difference between HF vs. NF and HF vs. F (P=0.009 and P=0.029, respectively). In the univariate analysis, the only significant prognostic factor impacting mortality was CFSS, with HF having an HR of 1.948 (95% CI 1.097-3.460, P=0.023). CONCLUSIONS When OA is a surgical option, frail patients should not be precluded, while HF should be carefully evaluated. The CFSS might be a good prognostic score for patients that may safely benefit from OA.

Abstract
Innate lymphoid cells (ILCs) have potent immune functions in experimental conditions in mice, but their contribution to immunity in natural conditions in humans remains unclear. We investigated the presence of ILCs in a cohort of patients with severe combined immunodeficiency (SCID). All ILC subsets were absent in SCID patients carrying mutations of IL2RG or JAK3. T cell reconstitution was observed in SCID patients upon hematopoietic stem cell transplantation (HSCT), but the patients still exhibited drastic reduction of ILCs in the absence of myeloablation, at the exception of rare cases of ILC1 reconstitution. Remarkably, the observed ILC deficiencies were not associated with any particular susceptibility to disease, with a follow-up extending from 7 to 39 years after HSCT. We thus report here the first cases of selective ILC deficiency in humans, and show that ILCs may be dispensable in natural conditions, if T cells are present and B cell function is preserved.

Abstract
The world of lymphocytes has recently expanded. A group of cells, innate lymphoid cells (ILC), has been defined. It includes lymphoid cells that have been known for decades, such as natural killer (NK) cells and lymphoid tissue-inducer (LTi) cells. NK cells recognize a vast array of tumor cells, which they help to eliminate through cytotoxicity and the production of cytokines, such as IFNγ. Advances in our understanding of NK-cell biology have led to a growing interest in the clinical manipulation of these cells in cancer. The other ILCs are found mostly in the mucosae and mucosal-associated lymphoid tissues, where they rapidly initiate immune responses to pathogens without the need for specific sensitization. Here, we outline the basic features of ILCs and review the role of ILCs other than NK cells in cancer. Much of the role of these ILCs in cancer remains unknown, but several findings should lead to further efforts to dissect the contribution of different ILC subsets to the promotion, maintenance, or elimination of tumors at various anatomic sites. This will require the development of standardized reagents and protocols for monitoring the presence and function of ILCs in human blood and tissue samples.

Abstract
The application of intestinal transplantation is limited by the high rate of infectious complications that can occur; the migration of enteric microorganisms to extraintestinal sites (bacterial translocation) has been suggested to be responsible for this event. We reviewed 95 intestinal biopsies performed on 28 transplanted patients to identify histologic features predictive of isolation of enteric microorganisms in extraintestinal sites within the first month after transplantation. At least 1 isolation of enteric microorganisms in the peritoneal cavity and/or in blood samples was obtained in 13 patients (46.4%); this event led to higher 1-year mortality (38.5% vs. 6.7%; P = .041). Of the 95 biopsies, 38 were followed by positive cultures (40.0%), showing higher degrees of mucosal vascular alterations (Ruiz grade) and ischemia/reperfusion injuries (Park/Chiu grade) compared with the negative cases (P < .05). We also observed an higher prevalence of positive cultures in relation to acute cellular rejection episodes (P = .091). Neither clinical or surgical factors nor immunosuppressive therapy were observed to be significantly related to positive cultures. Histologic alterations of the small bowel allograft are related to isolation of enteric microorganisms in extraintestinal sites. The degree of these histologic features can identify patients at high risk of potentially life-threatening infectious complications and death.

Abstract
Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) are the main cytosolic sensors of single-stranded RNA viruses, including paramyxoviruses, and are required to initiate a quick and robust innate antiviral response. Despite different ligand-binding properties, the consensus view is that RIG-I and MDA5 trigger common signal(s) to activate interferon regulatory factor 3 (IRF-3) and NF-κB, and downstream antiviral and proinflammatory cytokine expression. Here, we performed a thorough analysis of the temporal involvement of RIG-I and MDA5 in the regulation of IRF-3 during respiratory syncytial virus (RSV) infection. Based on specific RNA interference-mediated knockdown of RIG-I and MDA5 in A549 cells, we confirmed that RIG-I is critical for the initiation of IRF-3 phosphorylation, dimerization and downstream gene expression. On the other hand, our experiments yielded the first evidence that knockdown of MDA5 leads to early ubiquitination and proteasomal degradation of active IRF-3. Conversely, ectopic expression of MDA5 prolonged RIG-I-induced IRF-3 activation. Altogether, we provide novel mechanistic insight into the temporal involvement of RIG-I and MDA5 in the innate antiviral response. While RIG-I is essential for initial IRF-3 activation, engagement of induced MDA5 is essential to prevent early degradation of IRF-3, thereby sustaining IRF-3-dependent antiviral gene expression. MDA5 plays a similar role during Sendai virus infection suggesting that this model is not restricted to RSV amongst paramyxoviruses.

Abstract
The interferon regulatory factor (IRF)-3 transcription factor plays a central role in the capacity of the host to mount an efficient innate antiviral immune defense, mainly through the regulation of type I Interferon genes. A tight regulation of IRF-3 is crucial for an adapted intensity and duration of the response. Redox-dependent processes are now well known to regulate signaling cascades. Recent reports have revealed that signaling molecules upstream of IRF-3, including the mitochondrial antiviral-signalling protein (MAVS) and the TNF receptor associated factors (TRAFs) adaptors, are sensitive to redox regulation. In the present study, we assessed whether redox regulation of thiol residues contained in IRF-3, which are priviledged redox sensors, play a role in its regulation following Sendai virus infection, using a combination of mutation of Cysteine (Cys) residues into Alanine and thiols alkylation using N-ethyl maleimide. Alkylation of IRF-3 on Cys289 appears to destabilize IRF-3 dimer in vitro. However, a detailed analysis of IRF-3 phosphorylation, dimerization, nuclear accumulation, and induction of target gene promoter in vivo led us to conclude that IRF-3 specific, individual Cys residues redox status does not play an essential role in its activation in vivo.

Abstract
OBJECTIVE To investigate the possible antiapoptotic prosurvival role of the pregnane X receptor (PXR) in hepatic ischemia-reperfusion injury in rats using clotrimazole (CTZ), a strong PXR transactivator. MATERIALS AND METHODS Male Sprague-Dawley rats were divided into 3 groups of 6 each: sham-treated, control, and CTZ-treated animals. Control and CTZ-treated animals were subjected to 30 minutes of normothermic ischemia of the whole liver followed by 6 hours of reperfusion. The animals were then killed, and the liver was excised and blood samples collected. RESULTS Clotrimazole induced a significant increase in expression of the CYP3A gene, indicating PXR transactivation, whereas expression of the antiapoptotic Bcl-xL gene was not increased. Serum concentrations of aspartate aminotransaminase and alanine aminotransaminase were lower in CTZ-treated animals than in control animals (difference not significant). Levels of poly(adenosine diphosphate-ribose) polymerase, a caspase-3 substrate, remained significantly higher in the CTZ-treated group compared with controls (P < .05). Clotrimazole increased the expression of phospho-p 44/42 extracellular signal-regulated kinase 1,2 (P < .05). The gene expression of the heat shock proteins 27, 70 and 90 was significantly lower in CTZ-treated animals than in controls (P < .05). CONCLUSION Clotrimazole-mediated PXR transactivation protects the liver against ischemia-reperfusion apoptosis in rats. Phospho-p 44/42 extracellular signal-regulated kinase 1,2 is activated, whereas gene expression of heat shock proteins 27, 70, and 90 is downregulated by induction of PXR.

Abstract
Type-I interferons (IFN-I) are cytokines essential for vertebrate antiviral defense, including against herpesviruses. IFN-I have potent direct antiviral activities and also mediate a multiplicity of immunoregulatory functions, which can either promote or dampen antiviral adaptive immune responses. Plasmacytoid dendritic cells (pDCs) are the professional producers of IFN-I in response to many viruses, including all of the herpesviruses tested. There is strong evidence that pDCs could play a major role in the initial orchestration of both innate and adaptive antiviral immune responses. Depending on their activation pattern, pDC responses may be either protective or detrimental to the host. Here, we summarize and discuss current knowledge regarding pDC implication in the physiopathology of mouse and human herpesvirus infections, and we discuss how pDC functions could be manipulated in immunotherapeutic settings to promote health over disease.

Abstract
Following the discovery of innate immune receptors, the topics of innate immunity and its role in defense against infective agents have recently blossomed into very active research fields, after several decades of neglect. Among innate immune cells, natural killer (NK) cells are endowed with the unique ability to recognize and kill cells infected with a variety of pathogens, irrespective of prior sensitization to these microbes. NK cells have a number of other functions, including cytokine production and immunoregulatory activities. Major advances have recently been made in the understanding of the role of NK cells in the physiopathology of infectious diseases. The cellular and molecular mechanisms regulating the acquisition of effector functions by NK cells and their triggering upon pathogenic encounters are being unraveled. The possibility that the power of NK cells could be harnessed for the design of innovative treatments against infections is a major incentive for biologists to further explore NK cell subset complexity and to identify the ligands that activate NK cell receptors.

Abstract
Plasmacytoid dendritic cells (pDCs) are an important source of IFN-α/β in response to a variety of viruses in vivo, including murine cytomegalovirus (MCMV). However, the respective contributions of various infected organs, and within these of pDCs, conventional dendritic cells and other cells, to the systemic production of IFN-α/β or other innate cytokines during viral infections in vivo is largely unknown. Whether a specialization of pDC subsets in the production of different patterns of innate cytokines exists in vivo in response to a viral infection has not been investigated. Here, by analyzing for the first time directly ex vivo, at the single-cell level, the simultaneous production of up to three cytokines in pDCs isolated from MCMV-infected mice, we show that (i) pDCs are the quasi-exclusive source of IFN-α/β, IL-12 and tumor necrosis factor (TNF)-α, early during MCMV infection, in two immunocompetent mouse lines and with two viral strains, (ii) pDC activation for IFN-α/β production is organ specific and (iii) a significant proportion of pDCs simultaneously produce IFN-α/β, TNF-α and IL-12, although TNF-α and IFN-α/β appear more often co-expressed with one another than each of them with IL-12. Altogether, these results show a broad and non-redundant role of pDCs in early innate detection of, and defense against, viral infection. The data also show differences in the responsiveness of pDCs from different tissues and suggest distinct molecular requirements for pDC production of various cytokines. These observations must be taken into account when designing new antiviral vaccination strategies aimed at harnessing pDC responses.

Abstract
Understanding the mechanisms that help promote protective immune responses to pathogens is a major challenge in biomedical research and an important goal for the design of innovative therapeutic or vaccination strategies. While natural killer (NK) cells can directly contribute to the control of viral replication, whether, and how, they may help orchestrate global antiviral defense is largely unknown. To address this question, we took advantage of the well-defined molecular interactions involved in the recognition of mouse cytomegalovirus (MCMV) by NK cells. By using congenic or mutant mice and wild-type versus genetically engineered viruses, we examined the consequences on antiviral CD8 T cell responses of specific defects in the ability of the NK cells to control MCMV. This system allowed us to demonstrate, to our knowledge for the first time, that NK cells accelerate CD8 T cell responses against a viral infection in vivo. Moreover, we identify the underlying mechanism as the ability of NK cells to limit IFN-α/β production to levels not immunosuppressive to the host. This is achieved through the early control of cytomegalovirus, which dramatically reduces the activation of plasmacytoid dendritic cells (pDCs) for cytokine production, preserves the conventional dendritic cell (cDC) compartment, and accelerates antiviral CD8 T cell responses. Conversely, exogenous IFN-α administration in resistant animals ablates cDCs and delays CD8 T cell activation in the face of NK cell control of viral replication. Collectively, our data demonstrate that the ability of NK cells to respond very early to cytomegalovirus infection critically contributes to balance the intensity of other innate immune responses, which dampens early immunopathology and promotes optimal initiation of antiviral CD8 T cell responses. Thus, the extent to which NK cell responses benefit the host goes beyond their direct antiviral effects and extends to the prevention of innate cytokine shock and to the promotion of adaptive immunity. To fight viral infections, vertebrates have developed a battery of innate and adaptive immune responses aimed at inhibiting viral replication or at killing infected cells. These responses include the early production of innate antiviral cytokines, especially interferons α and β (IFN-α/β), and the activation of cytotoxic lymphocytes such as the innate natural killer (NK) cells and the adaptive CD8 T cells. While critical for antiviral defense, cytokine or CD8 T cell responses can be detrimental or even fatal to the host when deregulated. Therefore, we need to better understand how the different arms of antiviral immunity are regulated. In particular, NK cells are proposed to play a protective role in a variety of viral infection in humans, but the underlying mechanisms remain poorly understood. Here, in a mouse model of cytomegalovirus infection, we demonstrate that NK cells prevent an excessive production of IFN-α/β and promote more efficient antiviral CD8 T cell responses. We thus show that NK cells can help promote health over disease during viral infections by regulating both innate and adaptive immune responses. It will be important to examine in humans whether NK cells control innate cytokine production to prevent immunopathology and to promote adaptive immunity against herpesviruses, HIV-1, influenza, or SARS.

Abstract
The histological patterns of anti-androgen-treated prostate adenocarcinoma mimic high grade tumors classified according to the widely used Gleason scoring system. However, the biological characteristics of anti-androgen treated carcinoma are largely unknown. E-cadherin, alpha-catenin, and beta-catenin adhesion molecules are down-regulated in pharmacologically untreated high grade prostate carcinoma. In this study, we used immunohistochemical techniques to investigate their expression in twenty acinar adenocarcinomas after anti-androgen therapy in prostatectomy specimens. After adrogen ablation therapy, expression of all these adhesion molecules was higher than that of pretreatment biopsies of the same patient group and high grade matched untreated controls. These results emphasize the inaccuracy of the Gleason score for anti-androgen-treated prostate adenocarcinoma and the more differentiated phenotype of prostate adenocarcinoma after anti-hormonal therapy.

Abstract
To elucidate the biochemical pathways leading to spontaneous apoptosis in primary cultures of human and rat hepatocytes, we examined the activation of the caspase cascade, the expression of Bcl-2-related-proteins and heat shock proteins. Comparisons were made before and after dexamethasone (DEX) treatment. We show that DEX inhibited spontaneous apoptosis in a dose-dependent manner. DEX increases the expression of anti-apoptotic Bcl-2 and Bcl-x(L) proteins, decreases the expression of pro-apoptotic Bax and inhibits Bad translocation thereby preventing the release of cytochrome c, the activation of caspases, and cell death. Although, the expression of Hsp27 and Hsp70 proteins remained unchanged, the oncogenic protein c-Myc is upregulated upon DEX-treatment. These results indicate that DEX mediates its survival effect against spontaneous apoptosis by acting upstream of the mitochondrial changes. Thus, the mitochondrial apoptotic pathway plays a major role in regulating spontaneous apoptosis in these cells. Blocking this pathway therefore may assist with organ preservation for transplant, drug screening, and other purposes.
