COMPOSITIONS AND METHODS FOR INDUCING IMMUNE TOLERANCE IN TRANSPLANTATION RECIPIENTS

摘要

Embodiments disclosed herein relate to compositions and methods for inducing transplantation tolerance using immunomodulation agents. In certain embodiments compositions and methods disclosed herein, concern administering a composition including, but not limited to, anti-CD3 immunotoxin and administering a composition including, but not limited to, peripheral blood cells obtained from a donor of an organ, tissue or cells to be transplanted. In some embodiments, compositions and methods disclosed here can be used for modulating B- and/or T-cell-mediated immunity and/or rejection by reducing or eliminating anti-donor antibody production. Other embodiments concern modulating T-cell production in a subject preparing for, undergoing organ, tissue or cellular transplantation; or having or expected of developing GvHD for reducing the risk of, preventing or treating rejection or GvHD. In certain embodiments, combination compositions of anti-CD3 immunotoxin and peripheral blood cells from a donor are contemplated.
