Abstract

ABSTRACT Chemokines and chemokine receptors (CKRs) control the migration of leukocytes during the inflammatory process and are important immunological markers of type 1 (CCR5 and CXCR3) and type 2 (CCR3 and CCR4) responses. The coexpression of CKRs (CCR2, CCR3, CCR5, CXCR3, and CXCR4) and intracellular cytokines (interleukin-10 [IL-10], IL-4, tumor necrosis factor alpha [TNF-α], and gamma interferon [IFN-γ]) on T CD4 + and CD8 + peripheral cells from individuals with indeterminate (IND) or cardiac (CARD) clinical forms of Chagas' disease after in vitro stimulation with Trypanosoma cruzi antigens, were evaluated in this study. The percentage of T CD4 + and CD8 + cells coexpressing CCR5 and IFN-γ, CXCR3 and IFN-γ, and CXCR3 and TNF-α were higher in CARD than in IND individuals; on the other hand, the percentage of T CD4 + or CD8 + cells coexpressing CCR3 and IL-10 or coexpressing CCR3 and IL-4 were lower in CARD individuals than in IND individuals. In addition, a significant positive correlation between the expression of CCR5 or CXCR3 and IFN-γ was observed in CARD individuals contrasting with a significant positive correlation between the expression of CCR3 and IL-4 and of CCR3 and IL-10 in IND patients. These results reinforce the hypothesis that a T. cruzi -exacerbated specific type 1 immune response developed by CARD chagasic patients is associated with the development of heart pathology.
