723-BHB Enhances CAR T Cell Antitumor Function

The article investigates how β-hydroxybutyrate (BHB), a ketone body produced during a ketogenic diet, enhances the effectiveness of CAR T cell therapy in treating cancer. Through various mouse models and human volunteer data, researchers demonstrated that BHB metabolically reprograms T cells by fueling the TCA cycle and increasing ATP production. This boost in energy leads to superior tumor control, higher rates of cell proliferation, and increased cytokine production compared to standard diets. The study concludes that BHB supplementation is a practical and implementable strategy to improve the potency of adoptive immunotherapies. Furthermore, the findings indicate that these benefits require the continuous presence of BHB in the system rather than just during the initial cell manufacturing phase. Overall, the research highlights a significant link between dietary metabolites and the success of advanced cancer treatments.References: Liu S, Guruprasad P, Ramasubramanian R, et al. β-hydroxybutyrate enhances the metabolic fitness of CAR T cells in cancer[J].
