In vitro suppression of effector T cells by neonate Tregs. a Effector T cell division in the presence and absence of Tregs as determined by CFSE staining. b Effector T cell proliferation in the presence and absence of Tregs as determined by ³H-thymidine incorporation. c-e Effector T cell secretion of IFN-γ, IL-13, and IL-17 in the presence and absence of Tregs as measured by LUMINEX. Te: effector T cells; Tr: regulatory T cells (n = 8)
