A2 and A3-mediated inhibition is alphavirus-specific and cell-type-independent. (A) and (B) Infectious titers of the VEEV TrD strain in HMC3 and U87MG cells respectively, reported as PFU/mL. Cells were pre-treated with peptides (pA2/pA3) for 2 h prior to infection; or cells were treated with peptides and immediately co-infected with virus. (C) EEEV (GA97 strain) titers in U87MG cells following treatment with peptides A2 and A3. (D). RVFV titers (MP-12 strain) in Vero cells following treatment with peptides A2 and A3. All treatments were performed at a concentration of 10 µg/mL of each peptide and infected with respective virus at MOI = 0.1. n = 3; *p > 0.05; **p > 0.01; ***p > 0.001; ****p > 0.0001.
