Description
Visceral leishmaniasis (VL), caused by Leishmania spp protozoan parasites, can provoke overwhelming and protracted epidemics, with high casefatality rates. Despite extensive efforts towards the development of an effective prophylactic vaccine, no promising vaccine is available yet for humans. Multi-epitope peptide based vaccine development is manifesting as the new era of vaccination strategies against VL. Aim of the study was the design of chimeric peptides from immunogenic L. infantum proteins for encapsulation in PLGA nanoparticles (NPs) alone or in combination with MPLA adjuvant, or in PLGA NPs surface modified with an octapeptide mimicking TNF-alpha for DCs targeting, in order to construct a peptide-based nanovaccine. The in vitro evaluation of the above nanoformulations was performed in DCs isolated from HLA-A2.1 transgenic mice. Characterization of DCs transcriptional responses to these vaccine candidates via microarrays could improve our understanding of their mechanisms of action on DCs' functional differentiation and the type of adaptive immunity subsequently induced.

Description
Visceral leishmaniasis (VL) caused by Leishmania donovani and L. infantum is a potentially fatal disease. To date there are no registered vaccines for disease prevention despite the fact that several vaccines are in preclinical development. Thus, new strategies are needed to improve vaccine efficacy based on a better understanding of the mechanisms mediating protective immunity and mechanisms of host immune responses subversion by immunopathogenic components of Leishmania. In the present study, determination of the immune mechanisms related to infection or protective immune responses against VL using an experimental nanovaccine as a vaccine model was conducted through microarray analysis.

Description
Microglia have emerged as crucial players in the maintenance of mechanical hypersensitivity in models of chronic pain, including rheumatoid arthritis. Recent studies have suggested that there is a sexually dimorphic microglial involvement in chronic pain, but the debate is still ongoing. Here, we have used the collagen antibody-induced arthritis (CAIA) mouse model to ascertain possible differences between male and female microglia in the context of arthritis-induced pain. We have focused on the late phase of this arthritis model, when joint inflammation has resolved but mechanical hypersensitivity and microglial activation persist. We found that intrathecal administration of minocycline reversed mechanical thresholds to control levels in male, but not female mice. Moreover, we isolated resident microglia from the lumbar dorsal horns of male and female mice and observed a significantly lower number of microglial cells in females by flow cytometry analysis. Furthermore, genome-wide RNA sequencing results pointed to several transcriptional differences between male and female microglia, but no convincing differences were identified between control and CAIA groups. Taken together, these findings suggest that there are significant but subtle sex differences in microglial expression profiles independent of treatment. To what extent they help bring about the behavioural sexual dimorphism observed after minocycline administration remains to be explored. Finally, our experiments failed to identify the underlying biological correlates of the microglial activation that is present in the late phase of the CAIA model. It is likely that transcriptional changes are either subtle and highly localised and therefore difficult to identify with bulk isolation techniques or that other factors, such as changes in protein expression or epigenetic modifications are at play. Overall design: RNA-seq of male and female saline or CAIA treated mice

Description
Lymphatic valves are specialized units regularly distributed along collecting vessels that allow unidirectional forward propulsion of the lymph, and its efficient transport from tissues to the bloodstream. Lymphatic endothelial cells that cover lymphatic valve sinuses are subjected to complex flow patterns, due to recirculation of the lymph during the collecting vessel pumping cycle. They also express high levels of FOXC2 transcription factor.

Description
Acute liver injury is a critical life-threatening event. Common causes are infections, intoxication, and ischemic conditions. The cytokine Interleukin 22 (IL-22) has been implicated in this process. However, the role of IL-22 during acute liver damage is controversial, since both protective and pathogenic properties have been reported. IL-22 binding protein (IL-22BP, IL-22Ra2), a soluble endogenous inhibitor of IL-22, is able to regulate IL-22 activity, and thus might explain some of the controversial findings. Since the role of IL-22BP in liver injury is unknown, we used Il22bp deficient mice and mouse models for acute liver damage to address this point. We found that Il22bp deficient mice were more susceptible to ischemia- and acetaminophen- induced liver damage. Deficiency of Il22bp caused increased hepatic damage and delayed liver regeneration. Using an unbiased approach, we found that IL-22, if uncontrolled in Il22bp deficient mice, induced Cxcl10 expression by hepatocytes, thereby recruiting inflammatory CD11b+Ly6C+ monocytes into the liver upon liver damage. Accordingly, neutralization of Cxcl10 reversed the increased disease susceptibility of Il22bp deficient mice. In conclusion, our data suggest dual functions of IL-22 in acute liver damage, and highlight the need to control IL-22 activity via IL-22BP. Overall design: RNA sequencing of RNA isolated from liver tissue from mice that underwent liver reperfusion treatment (IR) or sham surgery, in triplicate for three genotypes (Wt, Il22-/- and Il22bp-/-).
