Latest Melissa Rolls Stories
A gene that is associated with regeneration of injured nerve cells has been identified by scientists at Penn State University and Duke University. The team, led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State, has found that a mutation in a single gene can entirely shut down the process by which axons -- the parts of the nerve cell that are responsible for sending signals to other cells -- regrow themselves after being cut or damaged. "We are...
By Katrina Voss, Penn State A team of scientists led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State University, has peered inside neurons to discover an unexpected process that is required for regeneration after severe neuron injury. The process was discovered during Rolls's studies aimed at deciphering the inner workings of dendrites -- the part of the neuron that receives information from other cells and from the outside world. The research will...
