Several other chemokines, involved in both the recruitment of neutrophils (CXCL1, 2, 3) and NK and T cells (CXCL16, CXCL9, CXCR3, CCR5) were found to be overexpressed in SS lesional skin, either at protein or RNA level, suggesting that not only innate but also adaptive immunity plays a role in SS. The gene discussed is CXCL1; the disease is synovial sarcoma.
