Scientists discovers protein that increases effectiveness of vaccines against cancer

Scientists from Boston University School of Medicine, US have discovered a protein that could help make vaccinations more effective and provide protection from diseases such as cancer. They had purified a protein found on the exterior of bacteria – neisseria meningitis and used it as an accessory to provide a better vaccination response. Typically, vaccines can either increase the amount of antibody production or they can stimulate cells called cytotoxic T cells to directly kill the offending agent. In this case, the protein called PorB is unique as it can do both.
