Antibody and Cotoxic lymphocyte(CTL) responses to the primary infection of northern pig-tailed macaques with HIV-1NL4−R3A and stHIV-1sv. (A) Antibody responses to HIV-1NL4−R3A and stHIV-1sv infection in NPMs were detected by western blotting analysis, the plasma at 4, 8, and 12 weeks postinfection (wpi) were used. (B) HIV-1 special neutralizing antibodies against these two viruses were measured respectively at 4, 12, 18 wpi. The inactivated plasma mixed with corresponding virus was added into Tzm-bl and the 50% reductions of virus infectivity (IC50) were calculated. (C) Cotoxic lymphocyte (CTL) responses to these two viruses were determined at 4 and 7 wpi. P-values were calculated by t-test.
