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.
