Progress in fighting cancer and infections with T cell therapy

The quest to bring immunotherapy into widespread clinical use against cancer and infectious diseases has made great strides in recent years. For example, clinical trials of adoptive T cell therapy are yielding highly promising results. The latest progress is being reported at the Annual Meeting of the American Association for the Advancement of Science.

T cell immunity has evolved to recognize and respond to health threats and provide a lifelong memory that prevents recurrent disease. However, with chronic diseases, reactive T cells often become inactive or even disappear. Recent advances have brought the idea of fighting chronic infections, and even cancers, by restoring protective T cell responses much closer to reality.

The main focus of the AAAS 2016 session "Fighting Cancer and Chronic Infections with T Cell Therapy: Promise and Progress" is on adoptive T cell therapy, in which a patient receives "killer" immune cells that target a disease-associated molecule. Several obstacles have stood in the way of widespread clinical use: identifying or generating T cells that will be most effective for each individual case, whether from the patient or from a suitable donor; avoiding or countering potential
side-effects; and finding ways to shorten the path from bench to bedside. Progress is being reported on all three fronts, including data from the first clinical trials.
