Abstract:
Anti-human immunodeficiency virus type 1 (HIV-1) activity was assessed in HIV-1-infected homosexual and bisexual men receiving 18-36 MIU/day of recombinant interferon (IFN)-alpha2a for Kaposi's sarcoma (KS). The median baseline HIV-1 RNA level was 4.99 log10 copies/mL. Seventeen subjects (68%) showed an RNA decline > or = .5 log10/mL, with a maximum at week 4 (median decline = 1.91, range = 3.64-1.15; P = .0007), after which RNA levels stabilized. Eight subjects (32%) with lower median initial CD4+ T cell counts (60 vs. 350 x 10(6)/L; P = .01) did not show RNA responses. Neither RNA nor KS responses were negatively affected by IFN-alpha2a dose modifications. Anti-HIV responses of KS responders (n = 15) and nonresponders (n = 10) did not differ. High-dose IFN-alpha can exert potent anti-HIV activity that is not associated with anti-KS activity.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
