Disruption of the CRL5 ubiquitin ligase complex enhances engineered T-cell persistence under chronic tumor antigen exposure

Abstract Engineered T-cell therapies are limited by progressive dysfunction under chronic tumor antigen exposure, and genetic perturbation of negative regulators has emerged as a promising strategy to sustain effector activity. We reanalyzed a genome-wide CRISPR knockout screen i...

Cullin-5 RING E3 ligase limits CD8⁺ T-cell persistence and effector responses during chronic antigen stimulation

Abstract T-cell exhaustion limits durable antitumor responses and remains a barrier to adoptive cell therapies (ACT) in solid tumors. To identify regulators of T-cell persistence, we performed genome-wide CRISPR knockout screens in primary human CD8⁺ T cells expressing an NY-ESO-...
