When looking at individual FTLD-tau diseases, five chemokines were significantly upregulated in PiD cases compared to controls: MCP1/CCL2 (P = 0.0058), MIP1α/CCL3 (P = 0.0023), MIP1β/CCL4 (P = 0.0290), IL-8/CXCL8 (P = 0.0077) and MDC (P = 0.0304) (Fig. 7). This evidence concerns the gene CCL3 and pelvic inflammatory disease.
