September 2024

Université Paris-Cité, Institut Cochin, Centre National de la Recherche Scientifique (CNRS) UMR8104, Institut National de la Santé et de la Recherche Médicale (INSERM) U1016, Paris, France.

Article Synopsis
  • Cancers evade the immune system, and effective immunotherapies, especially those targeting PD1, work by enhancing T-cell functions, particularly IFNγ production.
  • While immunotherapies have improved patient outcomes, not everyone responds, necessitating alternative treatments to enhance their effectiveness.
  • The study shows that iron supplementation boosts T-cell responses and enhances the effectiveness of anti-PD1 therapy in mice, indicating that combining iron with immunotherapy could improve cancer treatment outcomes.
