Abstract excerpt
Each of the three Th2 cytokine genes, IL-4, IL-5, and IL-13, has different functions. We hypothesized that Th2 heterogeneity could yield Th2 subpopulations with different cytokine expression and effector functions. Using multiple approaches, we demonstrate that human Th2 cells are composed of two major subpopulations: a minority IL-5(+) (IL-5(+), IL-4(+), IL-13(+)) and majority IL-5(-) Th2 (IL-5(-), IL-4(+),...
