Chemokine effects on Th17 cell recruitment.


<p>Migration assays were performed in a Transwell system. (A) Th17 cells migrate in response to recombinant human CCL17, CCL20 and CCL22 in dose-dependent manner (n = 5). Specific antibodies to chemokines significantly inhibit Th17 cell migration.***<i>P</i> < 0.001. (B and C) Expression of CCL20 by HeLa, Siha, and C-33A cells detected using Real-time PRC (B) and ELISA (C). All the three cervical cells could highly secrete CCL20 with highest level of CCL20 by HeLa cells. (D) Th17 cells also migrate toward culture supernatants of HeLa, Siha, and C-33A cells, which can be efficiently blocked by antibody against CCL20 alone or in combination with CCL17 and CCL22, but significantly less effectively by antibody against CCL17 or CCL22 (n = 3). *<i>P</i> < 0.05, **<i>P</i> < 0.01,***<i>P</i> < 0.001.</p
