CD4 from Azara's and Nancy Ma's owl monkeys are also permissive for HIV-1 entry. (A) Flow cytometry scatter plots showing CD4 expression of various primate alleles (indicated along the x axis) and human CCR5 expression (indicated along the y axis) in 293T cells. (B) 293T cells from panel A were infected with the indicated Env-pseudotyped virions. Infection was measured by flow cytometry as percent GFP-positive cells 72 h postinfection. All pseudotyped virions were generated in the Q23ΔEnvGFP background. Error bars represent the standard deviations obtained from duplicate wells. The results are representative of three independent experiments.
