Project description:We investigated antigen-specific avoidance behavior in mice, and found that is critically dependent on mast cells. We interrogated potential signaling routes between mast cells and the brain using mutant mice, pharmacological inhibition of serotonin receptor 3, neural activity recordings, and vagotomy. We analyzed gene expression comparing naive versus immunized wild type mice, and versus mast cell-deficient mice at different times following antigen exposure

Project description:Sib mating increase homozygosity and can lead to inbreeding depression. Selective pressures have favored the evolution of kin recognition and sib avoidance in mate choice. Such avoidance behavior has been recorded in the parasitoid wasp Venturia canescens where the sex determining system (single-locus complementary sex determination, sl-csd) introduces an extra short-term cost to inbreeding; females preferentially mate with unrelated males. The genetics underlying mate choice of females and kin recognition remains largely unexplored. Here we analyzed the head transcriptomic changes after exposure to distinct stimulus: courtship by unrelated male or courtship by brother, while transcriptome of females alone was used as control. Our results demonstrate that male courtship provokes a major transcriptome reprogramming in females heads. The transcriptomic response is highly dependent on the compatibility of the courting male. We subdivided the socially responsive genes using an integrative gene network analysis, we highlighted genes regulated by courtship, whatever the relatedness of the courting male. We also showed that the regulation of some peculiar group of genes is very specific of compatible male courtship, while others are regulated only by incompatible male courtship. We suggest that those different transcriptomic responses lead to mating decision or sib mating avoidance behavior observed in this species.

Project description:BACKGROUND: In asthma and other allergic disorders, the activation of mast cells by IgE and antigen induces the cells to release histamine and other mediators of inflammation, as well as to produce certain cytokines and chemokines. To search for new mast cell products, we used complementary DNA microarrays to analyze gene expression in human umbilical cord blood-derived mast cells stimulated via the high-affinity IgE receptor (FcϵRI). : One to two hours after FcϵRI-dependent stimulation, more than 2,400 genes (about half of which are of unknown function) exhibited 2-200 fold changes in expression. The transcriptional program included changes in the expression of IL-11 and at least 30 other cytokines and chemokines. Human mast cells secreted 130-529 pg of IL-11/106 cells by 6 h after stimulation with anti-IgE. CONCLUSION: Our initial analysis of the transcriptional program induced in in vitro-derived human mast cells stimulated via the FcϵRI has identified many products that heretofore have not been associated with this cell type, but which may significantly influence mast cell function in IgE-associated host responses. We also have demonstrated that mast cells stimulated via the FcϵRI can secrete IL-11. Based on the previously reported biological effects of IL-11, our results suggest that production of IL-11 may represent one link between IgE-dependent mast cell activation in subjects with allergic asthma and the development of a spectrum of structural changes in the airways of these individuals; such changes, collectively termed "airway remodeling," can constitute an important long term consequence of asthma.
