EXPERIMENTAL EVIDENCE OF BIOLOGICAL INTERACTIONS AMONG DIFFERENT ISOLATES OF TRYPANOSOMA CRUZI FROM THE CHACO REGION.

Experimental evidence of biological interactions among different isolates of Trypanosoma cruzi from the Chaco Region.

Many infectious diseases arise from co-infections or re-infections with more than one genotype of the same pathogen.These mixed infections could alter host fitness, the severity of symptoms, success in pathogen transmission and the epidemiology of the disease.Trypanosoma cruzi, the etiological agent of Chagas disease, exhibits a high biological var

Multiple autoimmune-associated variants confer decreased IL-2R signaling in CD4+ CD25(hi) T cells of type 1 diabetic and multiple sclerosis patients.

IL-2 receptor (IL-2R) signaling is essential for optimal stability and function of CD4(+)CD25(hi)FOXP3(+) regulatory T cells (Treg); a cell type that plays an integral role in maintaining tolerance.Thus, we hypothesized that decreased response to IL-2 may be a common phenotype of subjects who have autoimmune diseases associated with variants in the
