We designed to determine whether pretreatment of allografts with methoxypolyethylene glycol-succinimidyl-propionic acid ester (mPEG-SPA) and an anti-OX40L monoclonal antibody (McAb) can relieve acute graft-versus-host disease in allogeneic bone marrow transplantation recipients. Responder splenocytes from C57BL/6 donor mice were incubated with

Immunocamouflaged red blood cells (RBC) are produced by cell surface derivatization with methoxypolyethylene glycol (mPEG). These immunologically attenuated cells may reduce the risk of allosensitization in chronically transfused patients. To characterize the effects of differing linker chemistries and polymer lengths
