🧬 For decades, scientists believed the brain was a completely sterile world, but a new study shows otherwise!
In research published in Nature Portfolio, scientists at the Weizmann Institute of Science, together with teams at Rabin Medical Center - Medical Tourism in Israel and Rambam Health Care Campus - Hospital, discovered that brain tumours contain diverse communities of bacteria. These microbes were found inside cancer cells and nearby immune cells across more than 300 tumour samples.
The team, led by Prof. Ravid Straussman, found that different kinds of brain tumours carry different mixes of bacteria and that these microbes may influence how cancer behaves. Some types of bacteria seemed to help tumours grow or spread, while others affected how well treatments worked.
Together, these findings reveal a hidden world inside the brain and could one day guide more precise ways to diagnose or treat brain cancer.
