Immunocytochemistry of inflammatory infiltrates. (A). CD3 negative, (3 cell/mm2). (B). CD3 positive, (20 cell/mm2). (C). CD45Ro negative, (3 cell/mm2). (D). CD45Ro positive, CD45Ro (17 cell/mm2). (E). CD68 negative, (5 cell/mm2). (F). CD68 positive, (20 cell/mm2). (G). Mean of total expression of inflammatory infiltrates. Immunohistochemical illustrations are representative and obtained from one inflammatory-positive and one inflammatory-negative patient. ELISA data are presented as means ± SE from al least three independent measurements. Data were considered significant at **p < 0.01 and ***p < 0.001.
