Causes of gangrene and ulcers in diabetes patients

Diabetes patients can cause blood supply to cells in the body to be restricted and new blood vessels cannot be formed when there is a wound. Because of restriction in blood circulation, diabetes patients, wounds are slow to heal and diabetes patients frequently get gangrene and ulcers in their limbs. The reason could be a certain protein in the body cells. The cell is a protein receptor called p75NTR. This was discovered by Professor Peter Weissberg, of the British Heart Foundation.
