Hemokinski ligand 3 (C-X-C motiv) jest mali citokin koji je kod ljudi kodiran genom CXCL3 sa hromosoma 4. Pripada porodici CXC hemokina koja je poznata i kao onkogen GRO3 (GRO3), GRO proteinska gama (GROg) i makrofagni upalni protein-2-beta (MIP2b) .

Funkcija[uredi | uredi izvor]

CXCL3 kontrolira hemotaksijsku migraciju i adheziju monocita i posreduje svoje efekte na ciljnu ćeliju, interakcijom sa ćelijskom površinom hemokinskog receptora zvanog CXCR2.^[6]^[7] Nedavno je pokazano da Cxcl3 autonomno regulira migraciju prekursora neurona granulastih ćelija malog mozga prema njegovim unutrašnjim slojevima, tokom morfogeneze cerebelluma.^[8] Štaviše, ako je ekspresija Cxcl3 smanjena u prekursorima neurona cerebelumske granule, to značajno povećava učestalost meduloblastoma, tumora malog mozga. U stvari, smanjena ekspresija Cxcl3 tjera prekursore neurona malog mozga da ostanu na površini, gdje se jako razmnožavaju pod stimulacijom zvučnog ježa, postajući meta transformirajućih povreda. Zanimljivo je da tretman putem CXCL3 u potpunosti sprečava rast lezija meduloblastoma na mišjem modelu meduloblastoma tipa Shh.^[9] Stoga je CXCL3 meta za terapiju meduloblastoma. Cxcl3 je direktno reguliran transkripcijski, pomoću BTG2^[8]

Na hromosomu 4, gen za CXCL3 nalazi se u grupi drugih CXC hemokina.^[10]
