Background Regulatory T cells (Treg) play a crucial role in maintaining immune homeostasis and self-tolerance. dendritic cells (DCs) individually and in co-cultures with Tregs. Results TLR2 agonists can directly provide a co-stimulatory signal inducing enhanced proliferation and cytokine production of naive CD4+ Teff 20(S)-NotoginsenosideR2 cells. With respect to cytokine production DCs appear to be most… Continue reading Background Regulatory T cells (Treg) play a crucial role in maintaining
