Identifying PRRSV structural components that activate regulatory T cells and diminish protective immunity
April 26, 2010By Tanya LeRoith
This study was designed to test the hypothesis that certain structural components of PRRSV drive the activation of regulatory T cells (Tregs). Activating these T cells would thereby diminish the...
