Abstract：
:The small number of studies done on the covalent modification of RBC with PEG, or PEG-derivatives, suggests that the immunocamouflage of intact cells significantly reduces the antigenicity and immunogenicity of the foreign cell. Importantly, this protective immunologic effect can be accomplished without adversely affecting the structure, function, or viability of the modified cell (e.g., RBCs and lymphocytes). As a consequence, PEG-RBC may have significant practical value in the treatment of the chronically transfused patient as a prophylactic measure against allosensitization. The PEG-RBC also may be useful in treating the already allosensitized individual. As shown, preexisting antibodies do not effectively recognize nor bind to the modified donor cells. A finding of further interest to transfusion medicine is that pegylation of contaminating lymphocytes within RBC products may prove efficacious in preventing graft-versus-host disease in the immunocompromised patient. However, the main emphasis of our research continues to be the immunocamouflage of RBC for use in chronic transfusion therapy of the SCD and thalassemic patient.
