differential expression of cxcl1, cxcl9 cxcl10 and cxcl12 chemokines in alopecia areata

background: alopecia areata (aa) is a non-scarring, autoimmune disorder which causes hair loss. inflammatory reactions are involved in hair loss of the scalp and/or body. the involvement of chemokine receptors in the pathogenesis of aa is well defined among which, cxcl1 acts on neutrophils and cxcl9, cxcl10 and cxcl12 and serve as t lymphocytes recruiters. objective: to study the serum levels of elr+ and elr- cxcl1, cxcl9, cxcl10 and cxcl12 in the patients suffering from aa and healthy controls. methods: the study population of consisted of 30 patients suffering from aa and 30 healthy controls. serum concentrations of cxcl1, cxcl9, cxcl10 and cxcl12 were measured using enzymelinked immunosorbent assay (elisa). results: current results showed that aa patients had significantly elevated serum levels of cxcl9 and cxcl10 in comparison to controls (p
