Keeping tuberculosis in check

Mycobacterium tuberculosis is a major cause of death worldwide, and a formidable foe. Most healthy people can defend themselves against tuberculosis, but they need all parts of their immune system to work together. A study published in PLOS Pathogens reveals how a special class of immune cells called "invariant natural killer T cells" make their contribution to this concerted effort.

Specifically, 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.

For further details, refer to:
