Annexin A1 (1-11) is a peptide that is part of the annexin family. It is involved in the degranulation of cells and inhibits inflammation by inhibiting the production of pro-inflammatory cytokines. Annexin A1 (1-11) has been shown to be an anti-inflammatory compound as it binds to phospholipids on the surface of neutrophils, leading to inhibition of their chemotaxis and phagocytosis. This peptide also interacts with other annexins and prevents apoptosis by blocking caspase activity. Finally, it has been found that annexin A1 (1-11) can promote the healing of wounds in mice by accelerating reepithelialization and reducing scar formation. The concentration required for these effects are nanomolar concentrations.
