Cancer cells reprogram neutrophils to produce CCL3, aiding tumour growth: University of Geneva-led study

Exam-focused facts from the 8 February 2026 current affairs briefing.

Key facts

Cancer cells reprogram neutrophils to produce the chemokine CCL3, which promotes tumour growth.
The study was conducted by researchers at the University of Geneva and the Ludwig Institute for Cancer Research in Switzerland.
Neutrophils, usually defenders against infection, lose their pro-tumour action when CCL3 is absent.
The findings were published in the Cancer Cell journal.
