Biochem/physiol Actions

Lipoxin A4 (LXA4) is synthesized from arachidonic acid and is an endogenous lipoxygenase-derived eicosanoid mediator. It is a potent human protein kinase C activator. It inhibits cytotoxicity of natural killer cells. LXA4 regulates the immune system and inflammation. In the brain, it modulates neuronal signaling and slow wave sleep. LXA4 binds to cannabinoid receptors. LXA4 plays a key role in the maintenance of endometrium and reproductive function. Depletion of LXA4 contributes to the pathophysiology of cystic fibrosis (CF).

Resolution of inflammation is essential for tissue homeostasis and represents a promising approach to inflammatory disorders. Here we found that developmental endothelial locus-1 (DEL-1), a secreted protein that inhibits leukocyte-endothelial adhesion and inflammation initiation, also functions as a non-redundant downstream
