"Stopping this step in the life cycle of EBV could be a major potential target for the development of therapeutics for treating EBV-related B cell lymphomas," says Robertson.

In fact, Gupta points out that occasionally physicians discover that perfectly benign melanocytes will sometimes manage to migrate through a patient's body into, say, the lymph nodes. This phenomenon isn't related to cancer, but rather demonstrates the latent ability of m...Living anti-HIV gel shows early promise
