Interrupting T-Cell Memory Ameliorates Exaggerated Metabolic Response to Weight Cycling

We aimed to address a critical gap in understanding how persistent immune changes with weight cycling contribute to worsened metabolic health. We wanted to determine whether disrupting immune memory formation could prevent the accumulation and reactivation of memory T cells in adipose tissue and thereby protect against the metabolic dysfunction associated with weight cycling. In targeting the CD70-CD27 axis, thereby inhibiting T-cell memory formation, we were able to mitigate the exacerbated glucose intolerance observed in wild-type weight-cycled mice. This study highlights the potential to address the negative metabolic effects of weight cycling through an immunomodulatory approach, offering a novel therapeutic target by disrupting obesogenic immune memory.
