Interleukin 16

edit

Prointerleukin 16 je protein koji je kod ljudi kodiran IL16 genom.[1][2] Ovaj gen su otkrili 1982. godine Dr. David Center i Dr. William Cruikshank sa Bostonskog univerziteta.[3][4]

Protein kodiran ovim genom je pliotropski citokin koji funkcioniše kao hemoatraktant, modulator aktivacije T ćelija, i inhibitor HIV replikacije. Signalni prenos ovog citokin posreduje CD4. Proizvod ovog gena se podvrgava proteolitičkoj obradi, za koju je nađeno da proizvodi dva funkcionalna proteina. Citokinska funkcija se isključivo pripisuje izlučenom C-terminalnom peptidu, dok N-terminalni proizvod možda igra ulogu u kontroli đelijskog ciklusa. Za kaspazu 3 se zna da učestvuje u proteolitičkoj obradi ovog proteina. Dve alternativno splajsovane transkripcione varijante koje kodiraju dve različite izoforme su bile objavljene.[2]

Interleukin 16 (IL-16) je citokin koga oslobađaju mnoge vrste ćelija (uključujući limfocite i neke od epitelijalnih ćelija). On je karakterisan kao hemoatraktant za određene imune ćelije koje izražavaju na ćelijskoj površini molekul CD4.[5]

IL-16 je bio originalno opisan kao faktor koje može da privuče T ćelije kod ljudi, i on se ranije zvao limfocit hemoatraktant faktor (LCF).[3] Od tog vremena, za ovaj interleukin je bilo pokazano da može da regrutuje mnoge druge ćelije koje izražavaju CD4 molekul, uključujući monocite, eosinofile, i dendritske ćelije.[6]

Struktura uredi

IL-16 struktura je bila određena nakon kloniranja 1994. godine.[7] Ovoj citokin se proizvodi kao prekusor peptida (pro-IL-16) koji se mora skratiti enzimom kaspaza-3 da bi se aktivirao. CD4 je signalizacioni receptor za IL-16.

Interakcije uredi

Za interleukin 16 pokazano da formira interakcije sa Kir2.1,[8] KCNJ10,[8] GRIN2D,[8] GRIN2A,[8] PPP1R12B,[9] PPP1R12A[9] and KCNJ15.[8]
