Impaired expression of cell surface receptors for B cell growth factor by chronic lymphocytic leukemia B cells.

abstract：:Some patients lose chimerism following nonmyeloablative hematopoietic cell transplantation (HCT), yet, surprisingly, enjoy sustained tumor remissions. We hypothesized that host-versus-graft (HVG) alloresponses might induce antitumor effects against recipient tumors. We explored this question in mice by administering r...
