Although higher levels of EPCs have been associated with multiple myeloma (cancer of the plasma cells produced in bone marrow), their role in solid tumors has not been studied until now....10 top Australian scientists predict major medical advances

The liver possesses an unusual ability to stimulate immune tolerance, possibly due to its distinctive architecture that allows T cells normally activated in the lymph system to become activated by liver cells. Normally, endothelial cells that line blood vessels form a physical barrier that prevents na......s.
