Perhaps in association with the differences between the various forms of IC and murine CYP-induced cystitis, CXCL10 (followed by CXCL9) was higher in mice with CYP-induced cystitis, but CXCL9 (followed by CXCL10) was found to be higher in IC patients. This evidence concerns the gene CXCL10 and chronic cystitis.
