Evidence for T Cell Help in the IgG Response against Tandemly Repetitive Trypanosoma cruzi B13 Protein in Chronic Chagas Disease Patients
Figure 1
Direct ELISA for total IgG reactivity to recombinant B13 protein in the solid phase. 76 subjects bearing HLA alleles capable of presenting B13 peptides to T cells HLA-DQ7, DR1, and DR2 (HLA+), and 36 subjects bearing other HLA alleles (HLA−). The horizontal bar indicates median absorbance in each group. , Mann-Whitney Rank Sum Test.
