CSF3 and graft versus host disease: Using a murine leukemia model, several researchers have demonstrated that G-CSF mobilization of peripheral blood stem cell transplantation could maintain GVL effects through T cells via a perforin-dependent pathway and/or NKTs and prevent GVHD by reducing systemic levels of LPS and TNF-α as well as inducing a type 2 cytokine profile, CD34+ monocyte, and tolerogenic APCs (19, 76).
