Neuron transplant 'allows neurogenesis'

Research published in Science has found that by introducing brain matter from a healthy subject it is possible to repair defective brain circuits in mice.

The team behind the study suggested that cellular-level repair of the hypothalmus suggests the possibility that new therapeutic approaches could be developed for higher level conditions such as spinal cord injury, Parkinson's disease and Huntington's disease.

Jeffrey Macklis, professor of stem cell and regenerative biology at Harvard University, said that there are typically only two regions of the brain where neurogenesis take place.

He said: "Here we've rewired a high-level system of brain circuitry that does not naturally experience neurogenesis and this restored substantially normal function."

Earlier this month, researchers discovered that dendritic cells can protect against acute forms of pancreatitis and prevent dangerous swelling and inflammation of the gland.
