- Molecular studies of brain malformations.
Migration of neurons from their birth place to their final locations is essential during development of the mammalian brain. Disorders of neuronal migration result in severe malformation and malfunctions of the human brain. Our laboratory is interested in the guidance mechanisms involved in the neuronal migration. We are currently working on two projects. One project focuses on Slit proteins and their roundabout receptors which are believed to be involved in the guidance several populations of neurons. We are studying how heparan sulfate regulates Slit signaling in cell migration and axon guidance. The other project concerns the roles of protein O-mannosylation in neuronal migration. Congenital muscular dystrophies with brain malformations such as Walker-Warburg syndrome, Fukuyama congenital muscular dystrophy, muscle-eye-brain diseases are caused by genetic mutations in genes involved protein O-mannosyl glycosylation. We are currently studying the cellular and molecular mechanisms of protein O-mannosylation in regulating brain development.

Eric Wohlford received a 2012 travel award from the American Society of Tropical Medicine and Hygiene and spent two months in Kenya working in the lab of Rosemary Rochford, PhD, professor and chair of Upstate’s Department of Microbiology & Immunology. Eric studied the effects of malaria on B cells (producers of antibodies that fight infection) and Epstein-Barr Virus infection in the region. “Tropical medicine is unique, in that small, focused improvements in patient care make dramatic improvements in the well-being of patients,” he said.
