Abstract
Human immunodeficiency virus type 1 (HIV-1)-specific cytotoxic T lymphocyte (CTL) activity against different viral antigens, including env, gag/pol, and nef, was detected in peripheral blood lymphocytes of as many as 25% of uninfected children born to HIV-1-infected mothers. The relatively high frequency of this finding in uninfected, exposed children suggests that CTL-mediated immunity may play a key role in the control or even elimination of the virus. Further characterization of this natural model of potentially protective immunity could provide new insight and suggest further strategies for the development of HIV-1 vaccines.
