Texto completo da fonteIntroduction: Fetal infection during labor, accompanied by fetal inflammatory response syndrome (FIRS), is linked to neurodevelopmental impairments, cerebral palsy, neonatal sepsis, and even mortality. Existing diagnostic methods for FIRS remain insufficient. Acidosis associated with FIRS during labor presents a significant risk to the fetus. This study hypothesizes that analysing fetal heart rate variability (HRV) could serve as a tool for detecting FIRS. Therefore, the first study aim was to explore whether fetal HRV change during FIRS and the second aim was to explore how HRV changes during acute FIRS-associated hypoxia, compared to isolated hypoxia. Material and methods: In near-term fetal sheep with chronic instrumentation, lipopolysaccharide (LPS) was administered intravenously to simulate FIRS, while a control group received an injection of saline solution. Hemodynamic parameters, blood gas levels, interleukin-6 (IL-6), and 14 heart rate variability (HRV) indices were recorded during a stability period and for six hours after injection. For these different parameters, hourly comparisons were made between the LPS and control groups. For the second aim, two other groups were compared: one with isolated hypoxia, the other with hypoxia and FIRS. Worsening hypoxia was induced by repeated umbilical cord occlusions in three one-hour phases: mild, moderate, and severe. Hemodynamic, gasometric, and HRV parameters were compared between the groups. Results: For the first aim, a total of 15 lambs were instrumented. In the LPS-treated group (n = 8), IL-6 levels significantly increased following LPS administration (p < 0.001), validating the FIRS model. Additionally, fetal heart rate showed a significant increase after H5 (p < 0.01). Significant differences between LPS and control groups were observed between H2 and H4 for five HRV measures (Standard Deviation of Normal to Normal (SDNN), Standard Deviation 2 (SD2), Detrended Fluctuation Analysis (DFA) alpha 1 and 2 and Long-Term Variability (LTV)). The hypoxia and FIRS group had a higher mortality rate (n = 4/9) compared with isolated hypoxia group (n = 0/9). Gasometric state was altered earlier in the hypoxia and FIRS group after mild occlusions (pH = 7.22 [7.12–7.24] vs 7.28 [7.23–7.34], p = 0.01; lactate = 10.3 mmol/L [9.4–11.0] vs 6.0 mmol/L [4.1–8.2], p <0.001). After mild occlusions, the hypoxia and FIRS group had higher values for six HRV parameters compared with the hypoxia group (SDNN, Root Mean Square of Successive Differences (RMSSD), Short Term Variability (STV), LTV, Low Frequencies (LF) and High frequencies (HF). After moderate occlusions, only SDNN and RMSSD remained significantly higher. Conclusion: During acute FIRS, associated or not with hypoxia, HRV is significantly changed. These changes appear to be mediated by an increase of global variability and a loss of signal complexity. HRV indices may therefore be valuable for early detection in these two situations

Texto completo da fonteAids is characterized by chronic activation of the immune system. Different events lead to the production of interferons and pro-inflammatory cytokines. During the acute phase of infection, inflammation can be associated with fever episodes. To better understand the role of fever during HIV physiopathology, we studied the impact of hyperthermia on HIV replication in vitro. We showed that hyperthermia increases HIV replication in infected T lymphocytes. Single cycle infection in different cell lines was enhanced by 5-fold. Hyperthermia has no impact on viral entry or reverse transcription, but increases viral transcription. The heat shock protein Hsp90 is associated with transcription sites and plays a major role in the increased replication in hyperthermic conditions. We also showed that hyperthermia could favor viral reactivation in latently infected cells. We then studied the rote of the accessory protein Vpr in the modulat of innate immune responses. Our results showed that Vpr increased the synthesis of TNFa in T lymphocytes after infection. This release TNF a causes the nuclear transiocaiton of NfKB and may contribute the reactivation process in latently infected cells. This new activity of Vpr seems to correlate with its ability to arrest cell cycle of infected c in the G2 phase. We also observed a positive effect of Vpr on interf synthesis in dendritic cells. The study of the mechanisms by which hyperthermia and Vpr influence HIV replication and innate response should help to better characterize the role of inflammation in HIV-associated pathology

Texto completo da fonteSepsis is frequently observed in intensive care, with mortality around 50% (most severe cases). This pathology involves a systemic inflammatory response that occurs following infection. The immune System plays a major role in this inflammatory syndrome, with a potential progression toward an excessive response, dangerous for peripheral organs, or toward inadequate anti-inflammatory control and re-infections. The aim of this work was to precise mechanisms involved in this infection susceptibility, especially those related to monocyte. Results showed that peritonitis patients monocytes are able to differerentiate in vitro into dendritic cells (DC), in an accelerated manner. Ànalysis of these DC showed the emergence of a CD la- DC subset, which proportion is strongly increased in patients. T cells stimulated with control donors or patients CD la- DC do not proliferate. However, T cells cultured with control CD la- DC display Th2 and regulatory polarization, whereas patients CD la- DC favored Th1 profile. This polarization switch could enhance immune response against infection, but also peripheral tissue injury. By contrast, patients CDla+ DC potentially induced a stronger regulatory response in proliferating T cells, as suggested by increased Foxp3 expression, than did control CDla+ cells. These results suggest an additionnal and complex control of inflammatory and immune responses during sepsis, that could take place via the development of monocytes subsets, which remains to be characterized, and could result from a long-lasting cellular reprogramming process. The involvement of this process in the occurrence of secondary infections needs further investigations

Texto completo da fonteThe central nervous system (CNS) is considered as a unique immune-privileged environment allowing a basal immune surveillance under physiological conditions, and restraining potentially deleterious inflammatory reactions in disease states. Nevertheless, an immune response may develop in the CNS during infectious or inflammatory diseases. The inflammatory immune reconstitution syndrome affecting the CNS (neuro-IRIS) is a particular setting in which tissue damage may be due to the infectious agent itself, the immune response it has generated, or both. CD8 T cells are key players of the adaptive immune response involved in the pathogenesis of infectious or inflammatory diseases of the CNS. Our first aim was to clarify the role of CD8 T cells in the pathophysiology of IRIS that occurred in HIV-infected patients developing progressive multifocal leukoencephalopathy (PML), a severe demyelinating disease due to reactivation of the JC polyomavirus. Analysis by histology, immunohistochemistry and confocal microscopy of PML-IRIS lesions shows the dominance of CD8 T cells, among which a cytotoxic subset engaged JC virus infected oligodendrocytes. During PML-IRIS, the CD8 T cell response is beneficial in controlling JC virus infection, at the cost of increased destruction of infected oligodendrocytes. These results illustrate the role of CD8 T cells in the clearance of a neurotropic pathogen, but also in the genesis of collateral tissue damage. We then developed a murine model of neuro-IRIS based on the transfer of naive CD8 T cells reactive to a neo-antigen selectively expressed in oligodendrocytes of lymphopenic mice. We show that lymphopenia is necessary but not sufficient to trigger CD8 T cell-mediated CNS tissue damage. Development of neuro-IRIS also requires the overcoming of regulatory mechanisms, and the presence of CNS danger signals. These findings underscore the conditions necessary for the development of CNS tissue damage in a setting of immune recovery. This mouse model will help to test therapeutic strategies relevant for HIV-infected patients suffering from neuro-IRIS, aiming to modulate the deleterious immune reconstitution, without dampening it. The development of CNS tissue damage implies the migration of encephalitogenic cells across the blood-brain barrier. Little is known about adhesion molecules involved in the migration of CD8 T cells to the CNS. Using a panel of monoclonal antibodies blocking adhesion molecules or their ligands, we show in a murine model of CNS autoimmunity that migration of CD8 T cells is dependent on the integrin a4ß1. We further suggest that VCAM-1 is probably not the only ligand for a4ß1, and that other molecules may be involved. The identification of additional molecules specifically implicated in the migration of encephalitogenic cell populations may raise the potential for selective control of their trafficking into the brain, preserving better preserve the immune surveillance of the CNS. Ultimately, our work based on observations of neurological inflammation in both animal models and Humans helps to increase the knowledge on the mechanisms of migration and pathogenicity of CD8 T cells in the CNS
