Expression of cytokine-mRNA in peripheral blood mononuclear cell of human immunodeficiency virus-1 subtype C infected individuals with opportunistic viral infections from India (South)

Human immunodeficiency virus (HIV) disease progression is associated with a marked change in the level of plasma cytokines. The study reported here investigated the level of mRNA expression of different cytokines: Tumour necrosis factor-alpha (TNF-α), interferon (INF)-gamma, interleukin-10 (IL-10) and IL-21 in the peripheral blood mononuclear cell among the antiretroviral therapy naive subtype C HIV-1 infected individuals and normal healthy controls by real time polymerase chain reaction. The mRNA expressions of all the 4 cytokines in HIV-1 infected individuals were significantly higher compared to healthy controls (P value range 0.0004–0.01). The mean level of IL-10, INF-gamma and TNF-α were higher in HIV infected individuals with low CD4 counts (
