In contrast, the 02363-EG-infected group demonstrated almost entirely stable lymphocyte kinetics (Fig 3 and S2 Fig), indicating no apparent lymphocytopenia with the exception of monkey #5134 which exhibited a decline in CD3+CD4+, CD3+CD8+, and CD3-CD20+ lymphocytes in the later stages of infection, particularly at 10 days p.i. (Fig 3A, 3B, and 3D, right panel). The gene discussed is CD4; the disease is infection.
