Повний текст джерелаShort chain fatty acids (SCFAs) are metabolites produced mainly by the gut microbiota with a known role in immune regulation. Acetate, the major SCFA, is described to disseminate to distal organs such as the lungs. Moreover, the literature supports that acetate modulates inflammation and improves bacterial clearance. Our group has previously demonstrated that acetate improves Streptococcus pneumoniae clearance in the context of a secondary post-viral infection. This protection is mediated by alveolar macrophages, the first line of pulmonary immune defense. Thus, our aim was to evaluate the effect of acetate on the killing ability of alveolar macrophages and to delineate the mechanisms involved in this response. Here we show that acetate supplementation in drinking water modulated the secretion of host defense proteins by murine pulmonary cells and led to reduced S. pneumoniae loads in the lungs. To understand the mechanisms of bacterial clearance, alveolar macrophages were used. Transcriptomic analysis (RNAseq) revealed that acetate induced a specific signature of host defense in S. pneumoniae conditioned macrophages. This associates with the improved killing ability of acetate treated macrophages mediated by nitric oxide (NO) production. Increased NO concentration triggered by acetate was dependent on augmentation of IL-1β levels. Surprisingly, IL-1β production led by acetate was neither dependent on its cell surface receptor (Free-Fatty Acid Receptor 2), nor on the enzymes responsible for its metabolism (Acetyl-CoA Synthetase 1 and 2). Alternatively, acetate enhanced the glycolytic profile of macrophages resulting in greater HIF-1α activity which culminated in higher transcription of IL-1β. Moreover, the increased secretion of IL-1β triggered by acetate relied on NLRP3 inflammasome activation. In conclusion, we unravel a new mechanism of bacterial killing by acetate-activated macrophages. We show that acetate increased IL-1β production and secretion in a mechanism dependent on the axis glycolysis/HIF-1α and NLRP3, respectively. Consequently, higher levels of IL-1β resulted in augmented NO production and improved killing ability of alveolar macrophages

Повний текст джерелаRespiratory infections are a leading cause of morbidity and mortality worldwide. New viruses are constantly discovered and one of them, the human Metapneumovirus (hMPV), was identified in 2001. hMPV causes upper and lower respiratory infections ranging from cold- or flu-like illnesses to more severe and life-threatening infections such as pneumonia and bronchiolitis. hMPV is only second or third to human respiratory syncytial virus in frequency and sometimes as frequent as human influenza viruses in causing respiratory infections. The majority of severe infections caused by hMPV are seen in individuals having the weakest immune system such as young children, elderly and immunocompromised subjects. Many studies tend to demonstrate that severe viral respiratory infection during childhood can lead to asthma development later in life. Unfortunately, physicians have no vaccine or treatment to fight against severe hMPV infections. Genome and protein fonction analyses are offering promising avenues for the development of effective antivirals. Moreover, hMPV pathogenesis has been described in a murine model which now offers a convenient way to evaluate candidate molecules. This PhD project main goal was therefore to design new molecules against hMPV infections. For that matter, two steps of hMPV replication cycle were targeted, i.e., virus entry into the host cell which happens by a fusion mechanism, and viral genome replication inside the infected cell. The first molecule successfully identified is a fusion inhibitor, the HRA2 peptide that showed highly potent activity against hMPV in vitro but also in vivo. The second group of molecules corresponds to small interfering RNAs (siRNAs) targeting genes essential for hMPV replication. RNA interference has been a rapidly growing field since its first description in the 1990’s. Here, we identified two highly effective siRNAs against hMPV in vitro which target the nucleoprotein and phosphoprotein. Evaluation of these siRNAs in a murine model of hMPV infection also showed great possibilities.

Повний текст джерелаT cell immunity is involved in the defense against human papillomaviruses (HPV). Incidence and prevalence of HPV-induced clinical lesions are high in immunocompromised patients and concern oncogenic and/or non oncogenic cutaneous and mucosal HPV. In this work, T-cell immunity against HPV was studied in 2 models of HPV infection: - Epidermodysplasia verruciformis-like eruptions in the setting of HIV infection: clinical, virological et immunologic features were studied in a series of patients. The nadir of CD4+ T lymphocytes, the intensity and the length of T CD4+ deficiency were related on the development of clinical lesions induced by both bêta HPV or alpha HPV. The inefficacy of antiretroviral therapy on HPV-induced clinical lesions suggests that anti-HPV T-cell responses were ineffective. - Couples with women presenting with HPV16-induced classic vulvar intraepithelial neoplasia and their healthy male partners, who were longitudinally followed for 18 months. Anti-E2 protein T-cell responses are a marker of efficient control of HPV infection, either after treatment in women, or spontaneously in men. Since E2 protein is absent from viral particles, the presence of anti-E2 T-cell responses in healthy male partners indirectly proves that they have been infected by replicative HPV16. These results provide a strong argument in favor of prophylactic HPV vaccination of young men to decrease the spread of mucosal HPV diseases
