Funkcija

uredi

CCL4, poznat i kao makrofagni upalni protein – 1β (MIP-1β) je CC-hemokin sa specifičnošću za CCR5 receptore. To je hemoatraktant za prirodne ćelije ubice, monocite i niz drugih imunskih ćelija.[4]

CCL4 je glavni HIV-supresivni faktor koga proizvode CD8 + T-ćelije.[5]

Perforin niskomemorijski CD8+ T-ćelije koje normalno sintetizira MIP-1-beta.[6]

CCL4 proizvode: neutrofili, monociti, B-ćelije, T-ćelije, fibroblasti, endotelne i epitelne ćelije.[7]

Pokazalo se da je koncentracija ovog hemokina u obrnutoj vezi sa mikroRNK-125b. Koncentracija CCL4 u tijelu raste s godinama, što može uzrokovati hroničnu upalu i oštećenje jetre.[7][8]

Interakcije

uredi

Pokazano je da CCL4 komunicira sa CCL3.[9]

CCL4 se veže za receptore povezane sa G-proteinima CCR5 i CCR8.[7]
