Implications of CD4/CD8 ratios in Human Immunodeficiency Virus infections
Human Immunodeficiency Virus (HIV) is a major Public Health burden to the world despite all efforts to eradicatethe menace. HIV infection is characterized by profound CD4 T cell destruction, compromised mucosal barrierfunction and chronic immune activation. In addition, this infection is associated with a marked activation andexpansion of HIV-specific and bystander CD8 T cells. The impairment in CD4 T cell regeneration and the persistentelevation of CD8 T cell counts are considered to be a consequence of viral persistence and multiple inflammatoryfactors including gut microbial translocation, leading to major T cell dysfunction. The ratio of CD4/CD8 is veryimportant in the improvement of the lives of the HIV positive patients and should be carefully monitored and thebalance maintained.
