Adipose CoA handling is critical for lipid metabolism and homeostasis. Here, the authors identify TMEM120A as an ER-resident CoA binding protein enriched in adipocytes that promotes fatty acid recycling to support energy metabolism and limit lipotoxic stress, while its loss leads to adipose inflammation and metabolic dysfunction under high-fat diet conditions.

TCR-engineered T cells have shown limited efficacy in part due to the absence of co-stimulation leading to limited accumulation in solid tumors. The authors here show engineering the CD8β coreceptor with an intracellular CD28 domain enhances cytokine production, persistence, and tumor control in vivo independent of tumor-associated co-stimulatory ligand encounter.

Nicholas and Mattar found that people use episodic memory to make decisions when it is unclear what will be needed in the future. These findings reveal how the rich representational capacity of episodic memory enables flexible decision-making.
