Beschreibung:
The target of the CD8+ T cell-dependent immunity that protects mice immunized with irradiation-attenuated malaria sporozoites has not been established. Immune BALB/c mice were shown to develop malaria-specific, CD8+ T cell-dependent inflammatory infiltrates in their livers after challenge with Plasmodium berghei sporozoites. Spleen cells from immune BALB/c and C57BL/6 mice eliminated hepatocytes infected with the liver stage of P. berghei in vitro. The activity against infected hepatocytes is not inhibited by antibodies to interferon-gamma and is not present in culture supernatants. It is genetically restricted, an indication that malaria antigens on the hepatocyte surface are recognized by immune T effector cells. Subunit vaccine development will require identification of the antigens recognized by these T cells and a method of immunization that induces such immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoffman, S L -- Isenbarger, D -- Long, G W -- Sedegah, M -- Szarfman, A -- Waters, L -- Hollingdale, M R -- van der Meide, P H -- Finbloom, D S -- Ballou, W R -- New York, N.Y. -- Science. 1989 Jun 2;244(4908):1078-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Infectious Diseases Department, Naval Medical Research Institute, Bethesda, MD 20814.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2524877" target="_blank"〉PubMed〈/a〉
