2 Figure 1 T-cell proliferation induced by tuberculin or Candida antigens in the different TB risk groups. Bar graph depicting the stimulation index (proliferation) levels of T-cells for individuals from each of the groups in the presence of human AB or autologous serum: high-risk (HR), intermediate risk (group A), and low risk (group B). Treatment with autologous serum (with high levels of anti-tuberculin IgG antibodies, black solid bars) provokes the blocking of T-cell proliferation responses after stimulation with tuberculin (Bar graph A), but not with Candida antigen stimulation (Bar graph B). Only one subject from group B and two from group A exhibited blocking activity in the presence of autologous serum.
