Mechanisms of mast cell signaling in anaphylaxis.

29 Sep 2009 The recent development of a consensus definition and proposed diagnostic criteria for anaphylaxis offers promise for research efforts and a better understanding of the epidemiology and pathogenesis of this enigmatic and life-threatening disease. ... Read more...

Phospholipase d promotes lipid microdomain-associated signaling events in mast cells.

28 Sep 2009 Initial IgE-dependent signaling events are associated with detergent-resistant membrane microdomains. Following Ag stimulation, the IgE-receptor (Fc(epsilon)RI ) accumulates within these domains. This facilitates the phosphorylation of Fc(epsilon)RI ... Read more...

SH2 domain-containing phosphatase-2 protein-tyrosine phosphatase promotes Fc(epsilon)RI-induced activation of Fyn and Erk pathways leading to TNF(alpha) release from bone marrow-derived mast cells.

26 Sep 2009 Clustering of the high affinity IgE receptor (Fc(epsilon)RI) in mast cells leads to degranulation and production of numerous cytokines and lipid mediators that promote allergic inflammation. Initiation of FFc(epsilon)RI signaling involves rapid ... Read more...
