"We were interested in identifying the mechanisms that different types of T cells use to control Mycobacterium tuberculosis infection", says Samuel Behar, from the University of Massachusetts Medical School, US, the senior author of the new study.
He and his colleagues had previously shown that when invariant natural killer T (iNKT) cells encounter infected macrophages--the human target cells of Mycobacterium tuberculosis, or Mtb--the iNKT cells somehow prevented Mtb from growing and multiplying inside the macrophages.
