title: Type 1 and type 2: a fundamental dichotomy for all T-cell subsets.
abstract: Cytokine secretion is not confined to CD4+ T cells; rather, Type 1 and Type 2 populations of CD8+ and gamma delta T cells can also be generated in vitro and isolated from in vivo situations. These subsets and their physiological functions are significant.
