Abstract

Interleukin-7 (IL-7) plays a key role in maturation and function of both T and B cells. We investigate the potential use of recombinant human IL-7 for facilitation of graft-versus-leukemia (GVL) effects mediated by T cells following transplantation in a murine model. Administration of IL-7 in vivo to allogeneic-transplanted mice improved disease-free survival: 67% of mice treated with IL-7 remained alive and disease free for more than 60 days, in comparison to 17% of the controls (P<0.05). Similar results were obtained when C57BL/6 spleen cells sensitized against irradiated B-cell leukemia (BCL(1)) cells in the presence of IL-7 were transplanted to F(1) mice, followed by IL-7 treatment in vivo. Of the BALB/c mice that received spleen cells from F(1) mice treated with IL-7 following transplantation of C57BL/6 spleen cells sensitized with irradiated BCL(1) in the presence of IL-7, only 29% developed leukemia, as compared to 79% in the control group (P<0.05). Mice treated with IL-7 showed increased splenic and thymic cellularity and improved T cell-dependent proliferative responses compared to the controls (P<0.05). IL-7 may provide a novel tool to enhance immune reconstitution following transplantation of mismatched stem cells and for enhancement of GVL effects mediated by alloreactive lymphocytes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
