Immune Cells Turn Traitor: Study Reveals Neutrophils Can Fuel Tumor Growth

• A new study from the University of Geneva reveals that neutrophils, a type of immune cell, can inadvertently help tumors grow instead of attacking them.
• Led by Professor Mikaël Pittet, the research indicates that tumors create a complex environment where some cells switch allegiance and support cancer.
• The change is driven by a molecule called CCL3, which neutrophils start producing inside tumors, aiding cancer growth.
• Removing CCL3 prevented neutrophils from promoting cancer, even though they still gathered within tumors.
• This discovery could lead to better prediction of disease progression and more personalized cancer treatment strategies by targeting CCL3.
