Figure 5From: Postnatally-transmitted HIV-1 Envelope variants have similar neutralization-sensitivity and function to that of nontransmitted breast milk variantsNo difference in the efficiency of viral entry between Env virus variants from the milk of transmitting and nontransmitting women, or postnatally infected infants. (A) Infectivity ratio (TCID50/ml divided by p24 amount in ng/ml) of Env virus variants; (B) Inhibition of Env virus variant infectivity by CCR5 antagonist Maraviroc; (C) Inhibition of membrane fusion by entry inhibitor T20 peptide. Lines represent means IC50s (performed in duplicate for each virus) for each group of Env variants.Back to article page
