Effect of peptides on viral entry. HeLa-CD4⁺CCR5⁺ cells were infected with NLluc⁺env⁻ particles pseudotyped with different viral envelopes in the presence of peptides. Luciferase activity (r.l.u.) was measured 48 h after infection. The extent of entry in the absence of peptide was defined as 100% (r.l.u. ≈25,000 ± 9,000) and is represented by a horizontal dotted line. Background r.l.u. values were ≈7 ± 2. Each data point represents the mean ± SD of three replicates.
