DNMT1 targeting is established as a promising strategy to counteract CD8⁺ T cell exhaustion and potentiate ICI efficacy and enhances the effector function of melanoma patient-derived tumor infiltrating lymphocytes after prolonged ex vivo expansion.
A complementary therapeutic strategy is discussed: engineering T cells for greater durability in the TME through knockout of exhaustion-associated transcription factors, and reprogramming tumour cells with DNA methyltransferase (DNMTi) and histone deacetylase (HDACi) inhibitors to restore immunogenicity.

An epigenetic approach is described that facilitates the reversal of repressive DNA methylation and is used to alter the fate of T cell subsets for immunotherapy and is now used to alter the fate of T cell subsets for immunotherapy.

These findings highlight Dusp5 and Zfp219 as critical drivers of age-related T cell dysfunction that can be targeted to rejuvenate antitumor immunity in older cancer patients.

It is observed that ex vivo JAKi and TBK1i treatment, in a cancer cell intrinsic manner, induces a more stem-like CD8 T cell response following ICB, possibly through improved interactions with myeloid cells.

These findings define MDACs as an immunogenic myeloid subset and establish myeloid reprogramming as a strategy to improve radiotherapy-immunotherapy outcomes.

The aged tumor microenvironment can impair antitumor T cell function, but the molecular regulators that become limiting in this setting remain poorly defined. In a recent issue of Cell, Chen and colleagues harness in vivo CRISPR screening to compare the effects of genetic perturbations in tumor-reactive CD8+ T cells ac...
