Protective effects against tumors and infection by interleukin-27 through promotion of expansion and differentiation of hematopoietic stem cells into myeloid progenitors

Interleukin (IL)-27 is a multifunctional cytokine that belongs to the IL-6/IL-12 family and has potent antitumor activity through various mechanisms. Our novel findings indicate that IL-27 directly acts on hematopoietic stem cells and promotes their expansion and differentiation into myeloid progenitors to control infection and to eradicate tumors
