Scientists may have identified way of turning off immune response

Scientists believe they may have identified a way to turn off the immune response when patients receive a transplanted organ or bone marrow by manipulating T cells, which are key players in initiating and conducting immune responses.

In previous studies researchers identified a special group of T cells, called suppressor T cells, which can shut down the normal function of other important immune system cells called monocytes and dendritic cells.
