TRM in cancer immunotherapy. Several strategies have been proposed to enhance TRM activity. Checkpoint blockade may enhance intratumoral proliferation of TRM. DCs may be used as a vaccine to induce functional TRM. Targeting specific transcription factors and cytokines may drive TRM formation and may boost induction of active TRM. Targeting particular metabolites (e.g., FFA and FABP) may promote TRM pool and antitumor activity. Adoptive transfer of preprogramed TRM or TSCM may improve TRM seeding or differentiation, thereby enhancing antitumor immunity. PPAR, peroxisome proliferator–activated receptor.
