Study reveals how herpes virus tricks the immune system

With over half the U.S. population infected, most people are familiar with the pesky cold sore outbreaks caused by the herpes virus. The virus outsmarts the immune system by interfering with the process that normally allows immune cells to recognize and destroy foreign invaders. How exactly the herpes simplex 1 virus pulls off its nifty scheme has long been elusive to scientists.
