Scientists at the Sbarro Institute for Cancer Research and Molecular Medicine, Center of Biotechnology, located at Temple University’s College of Science and Technology, working with collaborators in Italy, have described the age-related differences in inflammatory response to an emerging immunotherapy treatment for non-small-cell lung cancer (NSCLC) called PD-1 blockade. These age-related changes to immune system response, known as immunosenescence, may have implications for the efficacy or the safety of immunotherapies for a variety of conditions and disease.
