Total IL-10 coverage directly correlated with neutrophil influx within caseous granulomas, with HIV coinfection associated with a small reduction in this correlation (M. tuberculosis–monoinfected persons, R2 = 0.6936, P = .0001; coinfected persons, R2 = 0.3906, P = .0004). The gene discussed is IL10; the disease is Granuloma.
