Full textTo develop a strategy against melanoma, we used murine peripheral blood mononuclear cells (pbmcs) against doxorubicin-resistant b16 murine melanoma cells. Pbmcs exhibited an anti-tumor effect in vitro but did not induce the inhibition of tumor growth in vivo. Although lysate-pulsed pbmcs induced a weak slowing down of tumor growth, mice survival was not modified. We showed that intra-tumoral (i. T. ) injections with unstimulated dcs slowed down tumor development, but did not increase survival of animals. Dcs pulsed with cytostatic tumor cells induced tumor regression when injected close to the tumor, and increased survival time in mice compared to untreated mice. When injected far from the tumor, their efficacy was reduced, but remains superior to unstimulated dcs. We observed that spleen cells of mice treated with pulsed dcs from tumor cells injection exerted a cytolytic activity against b16r cells upper than the control mice. Furthermore, an efficient and long-lasting protection of mice against b16r cells can be induced by preventive injections with pulsed dcs. These results show the relevant role of dcs in a specific anti-tumor immunity establishment. Consequently, dcs pulsed with cytostatic tumor cells could be used in addition to other treatments and improve their clinical outcomes

Full textMemory CD8 T cells (TMCD8) represent the major effector arm of the adaptive immunity by providing protective immunity against intracellular pathogens. Upon antigen-driven reactivation, TMCD8 differentiate into cytolytic, IFN-/TNF- secreting effector cells allowing for the control of the growth and the clearance of intracellular pathogens. Mice infected with a sublethal dose of the intracellular bacterium Listeria monocytogenes (Lm) develop TMCD8 which mediate protective responses against reinfection with a lethal dose of bacteria. However, neither expression of cytolytic nor IFN-/TNF--secreting activities is absolutely required for Lm clearance during a secondary infection. As an in vivo original approach, we analyzed the TMCD8 response in mice immunized with Lm mutants that do not induce protection. Using this system, we showed that CCL3 derived from reactivated TMCD8 is required for efficient killing of Lm. CCL3 induces a rapid TNF- secretion by inflammatory mononuclear phagocytics cells (MPC), which further promotes the generation of an oxidative burst by both themselves and neutrophils Oxidative burst is the final bactericidal mechanism involved in Lm clearance. These results uncover two levels of regulation of the protective response: (i) an antigen-dependent phase in which TMCD8 are reactivated and activate the innate immunity, and (ii) an antigen-independent phase in which the MPCs coordinate innate immunity and promote bactericidal effector activities. In this context, CCL3-secreting TMCD8 are able to mediate bystander killing of an unrelated pathogen upon antigen-specific reactivation, a mechanism that may be important for the design of therapeutic vaccines

Full textNewborns (children, ruminants) are particularly susceptible to intestinal infection by the parasite Cryptosporidium parvum because their immune system is still developing. To date, parasite control methods are limited. There is no vaccine and the only molecule which possess a marketing authorization for calves, Halocur ™, presents toxicity at 2 times the therapeutic dose. The development of new immunoprophylactic methods requires better understanding of the immune mechanisms occurring during infection. Innate immunity plays a major role in controlling the acute phase of infection and we previously demonstrated in the laboratory that intestinal mononuclear phagocytes CD11c+ are key players in the protection process. In this thesis, we confirmed the role of dendritic cells (DC) CD103+ using mice BatF3-/- in which the development of the two DC subsets CD103+CD11b+ and CD103+CD11b- is altered in the intestine making these animals more susceptible to infection. This high susceptibility can be partially mitigated by preventive administration of IL-12 to Batf3-/- neonatal mice. Batf3-/- adult mice which are only deficient for the CD103+CD11b- DC subset were transiently susceptible to infection in contrast to conventional mice that are highly resistant

Full textStaphylococcus aureus is a Gram positive bacteria leading to an increasing number of human pathologies. The goal of our work was to study the S. Aureus-induced cytokine production by phagocytic mononuclear cells (i. E monocytes, peritoneal and alveolar macrophages). We confirmed that TLR2 was dispensable for peritoneal macrophage response to S. Aureus. In contrast, TLR2 activation and phagocytosis were both required to obtain a full cytokine production in monocytes and alveolar macrophages. Furthermore, with specific inhibitors, we observed that p38 and Pi3K had a key role in both activation pathways. On the contrary, Racl and ERK were important for macrophages intracellular pathway. We then investigated which receptor was detecting S. Aureus after phagocytosis. Transfection of a dominant-negative form of NOD2 in RAW 264. 7 macrophagic cell line inhibited strongly NF-KB activation in response to S. Aureus. However, using NOD2-deficient primary cells, we observed that the absence of NOD2 did not alter cytokine production. Finally, NOD2-/- animals responses were comparable to wild-type after intra-nasal injection of S. Aureus. Nevertheless, NOD2-/- mice recovered faster than wild-type (weigh gain and pulmonary lesions). In conclusion, our work shows the existence of a TLR2-independant activation pathway that relies on phagocytosis. NOD2 does not play a critical role in S. Aureus response, both in vivo and in vitro. Finally, we show that, in phagocytic mononuclear cells, there is a great discrepancy in the role of phagocytosis in the response to S. Aureus. This work underlines the heterogeneity in the phagocytic cells response depending on the compartment they are derived from

Full textThe rapid spread of CA-MRSA is concerning all over the world due to multiple reports of overwhelming and tissue-destructive infections. This epidemic could become a public health problem in France if the virulence and behavior of this pathogen regarding antibiotics treatment is not fully understood soon. The aim of this work was to use different PK/PD models to better evaluate antibiotic activity against CAMRSA strains. Optimal dosing regimens of clinically available antibiotics against CA-MRSA were determined using an in vivo PK/PD infection model in mice. Susceptibility of antibiotics to the inoculum effect of CA and HAMRSA strains has been evaluated using an in vitro pharmacodynamic model simulating free drug concentrations in humans. This study shows that minocycline, linezolid, clindamycin and daptomycin activities are not affected by the inoculum effect, while TMP/SMX activity is significantly reduced at high inoculum. The impact of those antibiotics on CA-MRSA toxins gene expression has been studied using an in vitro PK/PD Hollow Fiber model. This study shows that clindamycin, minocycline and linezolid have an antitoxinic effect on CA-MRSA toxins while TMP/SMX significantly increases PVL production. This study was supplemented by the evaluation of the impact of those antibiotics at different concentrations on cytokines release from PBMCs after exposure to S. Aureus toxins. The protein synthesis inhibitors (tigecycline, linezolid, clindamycin) and TMP/SMX decrease cytokines release from PBMCs while azythromycin, daptomycin, vancomycine do not show any significant impact on the studied cytokines. As a conclusion, antibiotics activity against CA-MRSA can be define by their antimicrobial and antitoxinic activity and their impact on cytokines release from PBMCs. The protein synthesis inhibitors seem to be efficient antibiotic against CA-MRSA by limiting toxins production and exacerbated immune response. The antibiotic association TMP/SMX seems to be use carefully in severe CA-MRSA infections
