Discovery offers potential for stripping tumors of T cell protection

by  St. Jude Children’s Research Hospital Credit: CC0 Public Domain Immunologists at St. Jude Children’s Research Hospital have discovered that tumors use a unique mechanism to switch on regulatory T cells to protect themselves from attack by the immune system. Surprisingly, the mechanism does not affect regulatory T cell function outside the tumor and may therefore limit the...
