Altered Expression of PYCARD, Interleukin 1β, Interleukin 18, and NAIP in Successfully Treated HIV-Positive Patients With a Low Ratio of CD4+ to CD8+ T Cells

The expression and activity of main inflammasome components in monocytes from successfully treated HIV+ patients are poorly studied. Thus, we enrolled 18 patients with low and 17 with normal CD4/CD8 ratio compared to 11 healthy donors. Our results show that patients with low ratio have a decreased CCR2 expression among classical and intermediate monocytes and an increased CCR5 expression among classical, compared to whose with normal ratio. They also showed higher NAIP and PYCARD mRNA levels after LPS-stimulation suggesting an altered ability to control immune activation that could affect their immune reconstitution.
