Immunopharmacology Comments
Small molecule inhibitors of Rab27a-JFC1 binding, termed Nexinhibs (neutrophil exocytosis inhibitors) demonstrate the druggability of Rab GTPases and inhibition of exocytosis of azurophilic granules in human neutrophils without affecting other important innate immune responses, including phagocytosis and neutrophil extracellular trap production. These thus have potential use as an inhibitor of systemic inflammation [4].
