Abstract:Psychological stress triggers mast cell (MC) activation and is a major risk factor in the onset and exacerbation of MC-associated disorders including allergy/anaphylaxis, irritable bowel syndrome, and autoimmune diseases. The mechanisms by which stress modulates MC function and disease susceptibility is poorly understood. Our previous studies showed that corticotropin releasing factor receptor 1 (CRF1) signaling potentiated stress-induced MC degranulation. Here we utilized CRF2 deficient (CRF2 −/−) mice and MC… Show more
