NOVEL T CELL

摘要

A CD4-positive, CD25-positive regulatory T cell, which is a known regulatory T cell, cannot control an autoimmune disease by itself satisfactorily. Thus, the object is to search a regulatory T cell other than a CD4-positive, CD25-positive regulatory T cell, which can control an autoimmune disease satisfactorily. A study was made on the relationship between a regulatory T cell and Egr-2 gene which has been reported to be a transcription factor involved in T cell anergy. As a result, a novel T cell can be isolated, and the activities of the T cell can be elucidated.
