Fat Composition Affects T Cell-Mediated Immunity
A study from the University of Queensland and collaborators shows the dietary PUFA/MUFA ratio controls T cell susceptibility to ferroptosis. In mice, high PUFA/MUFA diets increased GPX4-dependent ferroptosis, depleting T_FH and CD8+ responses and reducing anti-tumor immunity, whereas low-ratio diets preserved T cell populations and slowed melanoma growth. The authors report preliminary plasma data from healthy human volunteers but provide limited detail in the article.
Why it mattersHigh PUFA/MUFA diets increased GPX4-dependent T cell ferroptosis, suggesting dietary adjustment for immunotherapy studies.
