BENEFICIAL EFFECTS OF PENTOXIFYLLINE ON CARDIAC AND IMMUNE TRAITS OF EXPERIMENTAL CHRONIC CHAGASIC CARDIOMYOPATHY ISABELA RESENDE PEREIRA¹, GLAUCIA VILAR-PEREIRA¹, JOSELI LANNES-VIEIRA¹. ¹Laboratório de Biologia das Interações, IOC–Fiocruz, RJ, Brasil; Introduction: Trypanosoma cruzi infection results in chronic Chagas cardiomyopathy (CCC) in about 30-40% of the infected individuals. CCC is characterized by prominent inflammation associated with fibrosis and electrical dysfunction. In the affected cardiac tissue, production of inflammatory mediators, chiefly pro-inflammatory cytokines and chemokines, might drive leukocyte migration contributing to CCC. Methods and Results: We tested the effect of pentoxifylline (PTX), a phosphodiesterase inhibitor, that also acts as an immunoregulator, upon immune response and heart dysfunction in C57BL/6 mice chronically infected with the Colombian strain of T. cruzi. PTX therapy did not alter the survival and parasite load, however improved cardiac function, reducing fibronectin (FN) deposition (13.5 ± 3.0% of FN positive area in salineinjected vs 6.9 ± 1.7% of FN positive area in PTX-treated mice, p
