NAD+ metabolism and its impact on CD8+ T cell aging — a research article exploring metabolic reprogramming as a contributor to immune senescence and inflammatory disease.
Key Takeaways
- Shifts toward altered NAD+ metabolism in CD8+ T cells drive their senescence and functional decline in disease contexts.
- Senescent CD8+ T cells with disrupted NAD+ homeostasis contribute to worsened intestinal inflammation in ulcerative colitis models.
- Restoring NAD+ balance in CD8+ T cells can reduce senescence markers and ameliorate colitis severity in experimental systems.
