Trypanosoma cruzi infection suppresses nuclear factors that bind to specific sites on the interleukin-2 enhancer.


Interleukin-2 (IL-2) gene expression, a critical early event during T lymphocyte activation, is severely suppressed in mice infected with the protozoan parasite Trypanosoma cruzi, the causative agent of human Chagas' disease. Our previous observation that reduction of IL-2 mRNA in T cells from T. cruzi-infected mice is not due to an increased degradation of… (More)
