title: Expression of the IL-1 receptor discriminates Th2 from Th1 cloned CD4+ T cells specific for Plasmodium chabaudi.
abstract: The expression of selected interleukin receptors by cloned CD4+ T cells specific for the murine malaria parasite Plasmodium chabaudi chabaudi (P. chabaudi) representative of the T-helper (Th) 1 and Th2 subsets was examined. Both sets of clones expressed receptors for those interleukins for which they had a growth factor requirement in vitro. Each Th1 clone expressed receptors for, and was responsive to, interleukin (IL)-2 and IL-4, while each Th2 clone expressed receptors for, and was responsive to, IL-2, IL-4 and IL-1. IL-1 receptor (IL-1R) expression by the Th1 clones was either negligible or could not be detected. The disparity in expression of IL-1R by the Th1 and Th2 clones was more clear-cut than has been previously reported and IL-1R provided a definitive phenotypic marker for clones of the Th2 subset. Should IL-1R expression prove to be a feature of other Th2 cells cultured long-term in vitro, this will be invaluable for investigations involving the phenotyping, depletion or selection of CD4+ T cells of either Th1 or Th2 subset.
