T cells are an important component of the body’s immune system. As ERIKA PEARCE explains, there are several types of T cells which form consecutively during the immune response and serve different purposes. Effector T cells combat pathogens from infections or tumors while memory T cells provide protective immunity to prevent re-infection or reoccurring cancer. The research presented in this video investigates how the metabolism of the T cells influences the development of effector and memory T cells by blending in vitro and in vivo approaches. * This LT Publication is divided into the following chapters: 0:00 Question 2:06 Method 3:29 Findings 5:05 Relevance 5:27 Outlook
