Description:
The genetic background of T lymphocytes influences development of the T helper (TH) phenotype, resulting in either resistance or susceptibility of certain mouse strains to pathogens such as Leishmania major. With an in vitro model system, a difference in maintenance of responsiveness of T cells to interleukin-12 (IL-12) was detected between BALB/c and B10.D2 mice. Although naive T cells from both strains initially responded to IL-12, BALB/c T cells lost IL-12 responsiveness after stimulation with antigen in vitro, even when cocultured with B10.D2 T cells. Thus, susceptibility of BALB/c mice to infection with L. major may derive from the loss of the ability to generate IL-12-induced TH1 responses rather than from an IL-4-induced TH2 response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guler, M L -- Gorham, J D -- Hsieh, C S -- Mackey, A J -- Steen, R G -- Dietrich, W F -- Murphy, K M -- AI31238/AI/NIAID NIH HHS/ -- AI34580/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1996 Feb 16;271(5251):984-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, Washington University School of Medicine, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8584935" target="_blank"〉PubMed〈/a〉
