on the activity of a pathway of signals that drives the multiplication of cells; p53 activates a self-destruct mechanism in cells whose DNA is so severely damaged that they might become cancerous. Previously, St. Jude investigators found evidence tha...

T cell 'brakes' lost during human evolution

system is not permanent, as we still have the Siglec genes in our genomes, and do continue to express them in other blood cell types," said Varki. "It is reasonable to hope that drugs can be found to turn the Siglec brakes back on again in human T c...
