CXCL8 and psoriasis: Further research has also determined that visfatin could act on the keratinocytes and amplify the inflammatory status through NF-κB and STAT3 signaling pathways and the upregulation of several chemokines gene expression, such as CXCL8, CXCL10, CCL20 and the antimicrobial peptides including cyclic adenosine monophosphate (CAMP) and S100A7 [75, 79], thus enhancing the severity of psoriasis.
