Description:
Characterization of the host immune response to human immunodeficiency virus type 1 (HIV-1) is critical to the rational design of an effective AIDS vaccine. In this study, cytotoxic T lymphocytes (CTL) specific for HIV-1 reverse transcriptase (RNA-dependent DNA polymerase) were found in blood samples from HIV-1-infected individuals. CTL targets were prepared by immortalizing B cells from ten seropositive and six seronegative individuals, and then infecting these cells with recombinant vaccinia viruses containing HIV-1 genes. CTL directed against autologous B lymphoblasts expressing HIV-1 reverse transcriptase were detected in fresh blood samples from eight HIV-1 seropositive subjects, but in no seronegative controls. The effector cells were identified as major histocompatibility complex-restricted CD3+CD8+ lymphocytes. Because the HIV-1 pol gene is highly conserved among different isolates and generates both humoral and cellular immune responses, it bears consideration for inclusion in a candidate AIDS vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walker, B D -- Flexner, C -- Paradis, T J -- Fuller, T C -- Hirsch, M S -- Schooley, R T -- Moss, B -- CA37461/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Apr 1;240(4848):64-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Infectious Disease Unit, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2451288" target="_blank"〉PubMed〈/a〉
