Outline of Final Research Achievements

Phospholipase A2s (PLA2s) are a group of enzymes that hydrolyze phospholipids to yield fatty acids and lysophospholipids, which serve as precursors for a variety of lipid mediators. It is currently acknowledged that classical lipid mediators such as arachidonic acid metabolites produced by PLA2s modulate mast cell-associated immune response. Moreover, mast cells express a variety of PLA2s or lipid receptors and can alter the release and production of other mediators including histamine, cytokines and chemokines, and thereby homeostatic or pathophysiological responses. Our current studies on newly acknowledged functional aspects of individual PLA2s or lipid receptors in mast cell-mediated immediate-type allergy in relation to non-canonical lipid pathway revealed that (1) the novel regulation of mast cells by a lipid mediator other than classical arachidonate metabolites and (2) the novel PLA2-driven lipid mediator pathway in the regulation of mast cell quality.
