Ceramide-CD300f binding suppresses experimental colitis by inhibiting ATP-mediated mast cell activation

Abstract

LMIR3-deficient colonic mast cells were pivotal in the exacerbation of DSS-induced colitis in LMIR3(-/-) mice. Ceramide liposomes attenuated DSS-induced colitis by inhibiting ATP-mediated activation of colonic mast cells through ceraimide-LMIR3 binding.
