Abstract:
Most of our knowledge concerning the presence of virus specific cytotoxic T lymphocytes (CTL) in early life has been provided by studies of CTL activities against human immunodeficiency virus type 1 (HIV-1) in infected infants born to HIV-infected mothers. HIV-specific cytolytic responses were found to be similar in perinatally infected children compared with adults, with respect to the nature of effector cells, protein recognized and the ability to control viral replication. CTL responses measured immediately after PBMC isolation (ex vivo activated CTL) were observed predominantly in children with no or mild symptoms, and the presence of in vitro activated CTL was found to be associated with the absence of severe symptoms during the first year of life and survival over 5 years.
