Dendritic Cells Testing T-Cells for Autoreactivity (image) University of Texas at Austin Share Print E-Mail Caption For the first time ever, UT Austin researchers captured the process in which developing killer T-cells (purple and white) are tested by dendritic cells (yellow), and others, to see if they react to normal proteins from the body. This safety check insures that the T-cells don't harm normal cells in the body and cause autoimmune disorders.
