ABSTRACT

Abstract The function of natural killer cells in tumors is often impaired due to metabolic adaptations of cancer cells, which causes reprogramming of natural killer cell effector and metabolic functions in favor of impaired immunity. As a result, targeting natural killer cells to solid tumors grapples with cells that meet a hostile environment unable to support effector functions. This not only results in cancers that are able to evade targeting, but also promotes natural killer cell dysfunction, most commonly manifested through altered phenotypic and functional signatures. In this chapter, we review the key elements driving natural killer cell metabolism, highlight the role of metabolism in supporting their function against solid tumors, and discuss targeting strategies to drive natural killer cells to solid tumors for immunotherapy.
