CCL20, hemokin (C-C motiv) ligand 20, ili jetrenom aktivacijom regulisani hemokin (LARC), ili makrofagni inflamatorni protein-3 (MIP3A) je mali citokin iz CC hemokin familije. On je snažno hemotaksan za limfocite, a slabo provlači neutrofile.^[1] CCL20 je impliciran u formiranje i funkciju mukoznog limfoidnog tkiva putem hemoatrakcije limfocita i dendritskih ćelija prema epitelnim ćelijama koje okružuju ta tkiva. CCL20 dejstvuje na svoje ciljne ćelije vezivanjem i aktiviranjem hemokinskog receptora CCR6.^[2]^[3]

CCL20 genska ekspresija može biti indukovana mikrobnim faktorima kao što su lipopolisaharidi (LPS), i inflamatorni citokini poput faktor nekroze tumora i interferon-γ, i umanjena uticajem citokina IL-10.^[4] CCL20 je izražen u više vrsta tkiva. Najobimnije izražavanje je primećeno u perifernim krvnim limfocitima, limfnim čvorovima, jetri, slepom crevu, i fetalnim plućima, a u nižim nivoima u timusu, testisima, prostati i crevima.^[1]^[5] CCL20 gen (scya20) je lociran na hromozomu 2 kod ljudi.^[6]
