CCL11, hemokin (C-C motiv) ligand 11, je mali citokin iz CC hemokin familije. On je takođe poznat kao eotaksin-1. CCL11 selektivno regrutuje eozinofile putem indukovanja njihove hemotakse, i zato je impliciran u alergijske response.[1][2][3]
Efekti CCL11 su posredovani njegovim vezivanjem za G-protein spregnutihemokin receptor. Hemokin receptori CCL11 liganda su CCR2[4], CCR3[5] i CCR5.[4] Međutim, bilo je ustanovljeno da eotaksin-1 (CCL11) ima visok stepen selektivnosti za CCR3 receptor, tako da je neaktivan na neutrofilima i monocitima, koji ne izražavaju CCR3.[6]Gen ljudskog CCL11 (SCYA11) je kodiran sa tri eksona i lociran je na hromozomu 17.[7][5]
