Abstract
HIV-1 env-pseudoviruses are a useful tool in the search for antiviral drugs (entry inhibitors) and evaluation of the efficacy of HIV-1 vaccines. Given the high genetic variability of HIV-1, it is necessary to regularly update the panels of pseudoviruses in accordance with the emergence of new strains. Based on genetic variants of HIV-1 circulating in the regions of the Siberian Federal District, 13 HIV-1 env-pseudoviruses of recombinant form CRF63_02A and subtype A6 were obtained. Most pseudoviruses have been shown to be sensitive to neutralization by bnAbs VRC01, PGT126, and 10E8, moderately sensitive to bnAbs PG9 and 4E10, and resistant to bnAbs 2G12, PG16, and 2F5. All obtained variants of pseudoviruses are CCR5-tropic.Entities:
