Using IBD patient sera, we have shown that the proinflammatory cytokines secreted during IBD may be classified further as inflammatory (IFN-γ and TNF-α) and regulatory (IL-6 and IL-7) cytokines, as well as chemokines (eotaxin, GRO, IL-8) [6]. The gene discussed is CXCL1; the disease is inflammatory bowel disease.
