As a potential treatment for Parkinson's disease, scientists at the University of North Carolina at Chapel Hill have created smarter immune cells [sciencedaily.com] that produce and deliver a healing protein to the brain while also teaching neurons to begin making the protein for themselves.

The researchers, led by Elena Batrakova, an associate professor at the UNC Eshelman School of Pharmacy's Center for Nanotechnology in Drug Delivery, genetically modified white blood cells called macrophages to produce glial cell-derived neurotrophic factor, or GDNF, and deliver it to the brain. Glial cells provide support and protection for nerve cells throughout the brain and body, and GDNF can heal and stimulate the growth of damaged neurons.

"Currently, there are no treatments that can halt or reverse the course of Parkinson's disease. There are only therapies to address quality of life, such as dopamine replacement," Batrakova said. "However, studies have shown that delivering neurotrophic factor to the brain not only promotes the survival of neurons but also reverses the progression of Parkinson's disease."
