The New Study   Tumors are known to be extensively innervated. Tumor cells produce a variety of neurotropic factors to attract neuronal differentiation. Why do they do this? Previous studies revealed that tumor cells use sensory neurons to suppress immune responses from CD8+ T cells. 1  In a new study, Hoover and colleagues identify a previously unknown reason for this close association. They discovered that tumor cells steal neuronal mitochondria to enhance survival, promote
