Funkcija uredi

CCL5 je 8 kDa protein koji je klasifikovan kao hemotaksni citokin ili hemokin. CCL5 je hemoatraktant T ćelija, eozinofila, i bazofila. On učestvuje u regrutovanju leukocita na mesta zapaljenja. Uz pomoć određenih citokina (npr., IL-2 i IFN-γ) koji se oslobađaju iz T ćelija, CCL5 takođe stimuliše proliferaciju i aktivaciju pojedinih tipova (NK) ćelija da formiraju CHAK (CC-hemokin-aktivirane ubice) ćelije.[3] CCL5 je takođe HIV-supresivni faktor koji izlučuju CD8+ T ćelije. Gen ovog hemokina je lociran na hromozomu 17 kod ljudi.[4]

RANTES je prvobitno bio identifikovan u toku potrage za "kasno" izraženim genima (3–5 dana) nakon T ćelijske aktivacije. Naknadno je bilo utvrđeno da je on CC hemokin i da je izražen u više od 100 ljudskih bolesti. RANTES izražavanje je regulisano u T limfocitima Krupel sličnim faktorom 13 (KLF13).[5][6][7][8]

Interakcije uredi

Za CCL5 se zna da formira interakcije sa CCR3,[9][10] CCR5[10][11][12] and CCR1.[10][12]

CCL5 takođe aktivira G-protein spregnuti receptor GPR75.[13]
