The annexin 1 receptor(s): is the plot unravelling?

Recent studies have proposed a functional link between annexin 1 (ANXA1), an endogenous anti-inflammatory mediator, and receptors of the formyl-peptide family. In particular, exogenous and endogenous ANXA1 and its peptidomimetics interact with one member of this family, the formyl-peptide-receptor-like 1. Further analyses of the interactions between ANXA1 and this and other members of this receptor family, and a better characterization of the ANXA1 receptor systems in models of inflammation, might clarify their mechanism of anti-inflammatory effects. This line of research will facilitate the development of ANXA1 mimetics and take advantage of >20 years of biological research into the functions of this glucocorticoid-modulated protein.
