DNA vaccination for induction of suppressive T cell response

摘要

A pro-inflammatory T response is specifically prevented by the injection into a recipient of DNA encoding the variable region of a T cell receptor. In response to the vaccination, T cells expressing the variable region produce Th2 cytokines, including IL-4. A pro-inflammatory T cell response directed to an autoantigen is shown to be suppressed by DNA vaccination. The suppressive vaccination further reduced the inflammatory effect of T cells reactive against epitopes of the autoantigen not recognized by the variable region used for vaccination.
