Regulating Bcl2L12 expression in mast cells inhibits food allergy.

ABSTRACT: Rationale: Mast cells play a crucial role in allergic diseases. Yet, the regulation of mast cell bioactivities is not fully understood. This study aims to elucidate the role of B cell lymphoma 2 like protein 12 (Bcl2L12), one of the anti-apoptosis proteins, in regulating mast cell apoptosis. Methods: A food allergy (FA) mouse model was developed to establish mast cell over population in the intestinal tissue. Either compound 48/80 (C48/80) or specific antigens were used to activate mast cells in the intestinal mucosa. Results: After treating with C48/80, apoptosis was induced in mast cells of the intestine of naive control mice, but not in FA mice. The expression of Fas ligand (FasL) was lower in the mast cells of FA mice. Interleukin (IL)-5 was responsible for the sup
