TLR7 and AIDS: Figure 1A shows that TLR7 mRNA levels in monocytes were significantly increased in SPs versus uninfected subjects, chronic HIV infection subjects, and AIDS subjects (p = 0.0483, p = 0.0473, and p < 0.0001 respectively), but were significantly decreased in AIDS subjects in comparison to uninfected subjects (p = 0.0252) and chronic HIV infection subjects (p = 0.0108).
