Antigen

infection by augmenting regulatory T cell numbers, which in turn down regulate the immune response to the parasite. larval antigen-specific cytokine responses in strongyloidiasis patients with or without HTLV-1 co-infection. larval antigens. Supernatants were analyzed for IL-5 production. antigen-specific IL-5 responses were reduced in strongyloidiasis/HTLV-1 co-infected patients (5.0 vs. 187.5 pg/ml, p = 0.03, Mann-Whitney test). Reduced IL-5 responses and eosinophil counts were inversely correlated to the number of CD4+CD25+FoxP3+ cells. hyperinfection
