Scholarcy highlights

  • Lymphocytes bearing the CD8 marker were shown to suppress replication of human immunodeficiency virus in peripheral blood mononuclear cells
  • The effect was dose-dependent and most apparent with autologous lymphocytes; it did not appear to be mediated by a cytotoxic response
  • This suppression of HIV replication could be demonstrated by the addition of CD8+ cells at the initiation of virus production as well as after several weeks of virus replication by cultured cells
  • The observations suggest a potential approach to therapy in which autologous CD8 lymphocytes could be administered to individuals to inhibit HIV replication and perhaps progression of disease
