Abstract
During human immunodeficiency virus type-1 (HIV-1) infection there are several changes in the frequency, phenotype and function of NK cells, altering their antiviral response. This is correlated with increased viral loads, and AIDS progression. However, studies in individuals with natural resistance to HIV-1 infection have shown that NK cells are very important in controlling viral replication, not only for their antiviral activity, but also because of their effects on the activity of other innate immune cells, such as dendritic cells. NK cells do not have antigen receptors, but it has been recently reported that they can specifically respond to HIV-1 peptides. Although the mechanism is not fully elucidated, this finding open more options in the study of new therapeutic or preventative strategies against HIV-1 infection.
