Where this comes from

Abstract

Although a role for mitochondrial transfer has been implicated in metastasis, the mechanisms are unclear. Using mouse metastatic models, Okwan-Duodu and colleagues<sup>1</sup> report that mitochondrial transfer from non-cancer immune cells to cancer cells in the tumor facilitates lymph node metastasis via the cGAS/STING immune evasion pathway involving type I interferon.
