CXCL1, hemokin (C-X-C motiv) ligand 1, je mali citokin koji pripada CXC hemokin familiji. On se ranije zvao GRO1 onkogen, GROα, KC, neutrofil-aktivirajući protein 3 (NAP-3) i melanoma rast stimulišuća aktivnost, alfa (MSGA-α). Kod ljudi, ovaj protein je kodiran CXCL1 genom.[1][2]
Funkcija
CXCL1 izlučuju ljudske ćelije melanoma. On ima mitogene osobine i učestvuje u patogenezi melanoma.[3][4] CXCL1 izražavaju makrofage, neutrofili i epitelske ćelije,[5][6] i dejstvuje kao neutrofilni hemoatraktant.[7][8] CXCL1 igra ulogu u razvoju kičmene moždine putem inhibicije migracije oligodendrocit prekursora, i učestvuje u procesima angiogeneze, inflamacije, zarastanja rana, i tumorigeneze.[9][10][11][12]
Ovaj hemokin dejstvuje putem signaliziranja kroz hemokin receptor CXCR2.[9] Gen za CXCL1 je lociran na ljudskom hromozomu 4 među genima za drugih CXC hemokina.[13] Jedna početna studija na miševima je proizvela evidenciju da CXCL1 umanjuje težinu multiple skleroze i da možda može da ima neuroprotektivnu ulogu.[14]
