Old mystery solved, revealing origin of regulatory T cells that 'police' and protect the body
More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years.   view more (2005-10-13)
