Abstract: Continuous specific downmodulation of CD4 receptor expression in T-lymphocytes by the small molecule cyclotriazadisulfonamide (CADA) selected for CADA-resistant HIV-1NL4.3 virus containing unique mutations in the C4 and V5 regions of gp120, likely stabilizing the CD4 binding conformation. The amino acid changes in Env were associated with decreased susceptibility to anti-CD4 mAb treatment of the cells, and with higher susceptibility of the virus to sCD4. In addition, the acquired ability of CADA-resistant virus to infect cells with low CD4 expression was associated with increased susceptibility of the virus to neutralizing antibodies from sera of several HIV-1 infected patients.
