TLR2 and HIV-1 infection: The results showed a significantly increased rate of HIV-1 infection in TZMbl cells overexpressing TLR10 and heterodimers TLR1 or TLR2 compared to the empty vector alone, uninfected control or a T20 control (Enfuvirtide; HIV-1 fusion inhibitor) (30, 31) (Figure 3A; P < 0.05).
