Active aldehydes accelerate CD8⁺ T cell exhaustion by metabolic alteration in the tumor microenvironment

Puntos clave

• CD8⁺ T cell exhaustion is significantly accelerated by active aldehydes in the tumor microenvironment, altering metabolism and immune response.
• Active aldehydes were linked to increased markers of cell exhaustion in key immune pathways, particularly impacting tumor-infiltrating lymphocytes.
• Analysis of metabolic changes highlights critical interactions between tumor metabolites and immune cell function.
• Understanding these metabolic alterations may suggest new therapeutic strategies to mitigate T cell exhaustion in cancer.
