Interleukin 11 (IL-11) je protein koji je kod ljudi kodiran IL11 genom.[1][2]
IL-11 je multifunkcionalni citokin koji je prvo izolovan 1990. godine iz kičmene moždine-izvedenih stromalnih ćelija. On je ključni regulator of više evenata hematopoeze, pogotovu stimulacije sazrevanja megakariocita.[3] On je isto poznat pod imenima inhibitorni faktor adipogeneze (AGIF)[4] i oprelvekin.
U poređenju sa drugim interleukinima, IL-11 je relativno slabo karakterisan.
Struktura[uredi | uredi kod]
LJudski IL-11 gen, koji sadrži 5 eksona i 4 introna, je lociran na hromozomu 19,[1] i kodira 23 kDa protein. IL-11 is je član IL-6 citokinske familije, koja je osobena po upotrebi zajedničkog koreceptora gp130. Signal specifičnost daje IL-11R alfa podjedinica.
Signalizacija[uredi | uredi kod]
Prenos signala se inicira nakon IL-11 vezivanja za IL-11R alfa i gp130, što omogućava homodimerizaciju gp130 molekula. Ovo omogućava gp130-asociranoj JAK kinazi da se aktivira i da fosforiliše intracelularne tirozinove ostatke na gp130.[5][6]
Funkcija[uredi | uredi kod]
Za IL-11 je bilo pokazano da poboljšava oporavak trombocita nakon hemoterapijom-uzrokovane trombocitopenije, inducira akutnu fazu proteina, modulira antigen-antitelo odziv, učestvuje u regulaciji proliferacije i diferencijacije koštanih ćelija, i možda može biti korišćen kao terapeutik za osteoporozu. IL-11 stimuliše rast određenih limfocita, i u modelu na glodarima, stimuliše povećanje kortikalne debljine i jačanje dugačkih kostiju. Pored toga što ima limfopoetske/hematopoetske i osteotrofske osobine, on funkcioniše u mnogim drugim tkivima, uključujući mozak, creva i testise.
