  • 1

    T cell immunotherapies face challenges in solid tumors due to nutrient-poor and oxidative tumor microenvironments.

  • 2

    Reactive oxygen species (ROS) are crucial for T cell activation and function, but excessive ROS can lead to T cell exhaustion.

  • 3

    Methionine metabolism and the GCN2 pathway are interconnected regulators that influence T cell redox state and metabolic responses.

  • 4

    Therapeutic manipulation of methionine availability and ROS can produce variable outcomes in cancer immunotherapy.

  • 5

    Emerging strategies, including integrated omics and CRISPR screening, aim to enhance T cell therapies by modulating metabolic pathways.
