Additionally, whereas CD8 and CD4 T cell levels were similar in AT-SVF of uninfected healthy monkeys (ratio of 1.38, p = 0.18), the ratio of AT-SVF CD8 to CD4 T cells increased during infection and disease (1.51 during SHIV infection, and 1.59 during chronic enterocolitis, p < 0.05) (Fig. 1c). The gene discussed is CD4; the disease is infection.
