Identification of Antigens Recognized by Murine Intestinal IgAs by a Gel-Independent Immunoproteomic Approach.

As part of the intestinal microbiota, can elicit a humoral response in the gastrointestinal tract (GIT) that is mainly directed toward hyphal antigens. This response has been implicated in controlling the invasive form of the fungus and maintaining the yeast as an innocuous commensal. However, the specific targets of this response are still unknown.

Vaccines for immunological defense against traumatic brain injury.

Unlabelled: Traumatic brain injury (TBI) and subsequent neurodegeneration is partially driven by chronic inflammation both locally and systemically. Yet, current clinical intervention strategies do not mitigate inflammation sequalae necessitating the development of innovative approaches to reduce inflammation and minimize deleterious effects of TBI. Herein, a subcutaneous formulation based on polymer of alpha-ketoglutarate (paKG) delivering glycolytic inhibitor PFK15 (PFKFB3 inhibitor, a rate limiting step in glycolysis), alpha-ketoglutarate (to fuel Krebs cycle) and peptide antigen from myelin proteolipid protein (PLP139-151) was utilized as the prophylactic immunosuppressive formulation in a mouse model of TBI.

The atypical soluble guanylyl cyclase subunit Gyc89Db does not control neuroepithelial proliferation in larval brain.

We investigated the role of oxygen-sensing atypical guanylyl cyclase subunit Gyc89Db in the developing brain. Despite its expression in the hypoxic neuroepithelium of the larval optic lobe of , loss-of-function mutants and ectopic expression did not alter neuroepithelial cell number or proliferation. Notably, while ectopic expression of increases optic lobe volume and neuroblast numbers, our negative results suggest that these effects manifest earlier in development without persistent alteration of the neuroepithelium, through mechanisms that might be independent of neuroepithelial proliferation.
