 AB    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.
