Increased proportions of regulatory T cells in strongyloidiasis/HTLV-1 co-infected patients.

<p>Comparison of regulatory T cell proportions (CD25+FoxP3+ among CD4+ T-cells) between healthy controls (blue, n = 17), patients with strongyloidiasis without HTLV-1 infection (red, n = 27), HTLV-1 asymptomatic carriers (orange, n = 9) and strongyloidiasis/HTLV-1 co-infected patients (green, n = 13). Co-infected patients had a significant increase of regulatory T cells compared to non-HTLV-1 patients. (* = P<0.05, One-way ANOVA). Lima, Peru.
