ESTIMATION OF mRNA LEVELS OF INTERLEUKIN (IL) -10, TUMOR NECROSIS FACTOR (TNF) - α, IL - 4 AND INTERFERON (IFN) - γ IN HIV INFECTED CHILDREN IN MUMBAI
Journal Title: Indian Journal of Clinical Biochemistry - Year 2006, Vol 21, Issue 1
Abstract
Cytokines, viral load and opportunistic infections play an important role in HIV-disease progression. Hundred children vertically infected with HIV were enrolled to determine mRNA levels of TNF-α, IL-10, IL-4 and IFN -γ. These levels were estimated by amplifying cytokine mRNA from peripheral blood mononuclear cells. Severity of HIV was staged by the reduction in CD4 + T cells and the onset of opportunistic infections. IL- 10 mRNA levels were observed to increase with the severity. Despite the rising IL-10 mRNA levels, TNF-α mRNA levels increased with severity of HIV and decrease in CD4 + T cell counts. IL-4 mRNA levels increased with the reduction in CD4 + T cell numbers. Depleting mRNA levels of IFN - γ contributed to the worsening of HIV disease. Increase in TNF-α and IL-4 levels appended to the disease severity by upregulation of the viral replication. Increased IL-10 levels and decreased IFN-γ levels predisposed the children to HIV associated opportunistic infections, which in return contributed to cytokine disarray.
