Thus, therapies that inhibit T-cell exhaustion are critical for optimizing cancer treatment. Recent studies have implicated epigenetic proteins in T-cell exhaustion. Here, we identified activating transcription factor 7 interacting protein (ATF7ip) as an epigenetic protein critical for inducing T cell exhaustion. Loss of Atf7ip in CD8+ T cells resulted in decreased terminal exhaustion and increased numbers of progenitor-exhausted cells in both chronic viral infections and cancer. Given the decreased T cell terminal exhaustion observed with Atf7ip-deficiency in CD8+ T cells, this may be one mechanism that leads to decreased tumor burden. Mechanistically, ATF7ip functions to stimulate the deposition of repressive H3K9me3 at critical immune-effector gene loci, such as Il7r and Il2 leading to enhanced exhaustion. Our data suggest that ATF7ip may be a rational target for deletion in adoptive T-cell therapies to reduce CD8+ T-cell exhaustion.<\/p>\n<p>PMID:<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/41973040\/?utm_source=SimplePie&amp;utm_medium=rss&amp;utm_content=101614637&amp;ff=20260413131008&amp;v=2.19.0.post6+133c1fe\">41973040<\/a> | DOI:<a href=\"https:\/\/doi.org\/10.1158\/2326-6066.CIR-25-0816\">10.1158\/2326-6066.CIR-25-0816<\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Cancer Immunol Res. 2026 Apr 13. doi: 10.1158\/2326-6066.CIR-25-0816.
