Chemokines and IFN-γ were assayed in PBMCs against PBMC-grown NL-LucR.T2A-Env.ecto reporter HIV-1 expressing the indicated envs. Values are the concentration at which RLU were reduced 80% compared to virus control wells after subtraction of background RLU in cell control wells. ND, inhibition experiments were not done with these viruses.
