Zhen Li, a researcher from Tufts University, dives into groundbreaking findings on a novel nanobody that targets the V-ATPase c subunit to combat breast cancer metastasis. The conversation highlights how the nanobody disrupts acidification within tumor cells and significantly curtails their ability to invade. Intriguingly, the group demonstrates that this innovative approach also minimizes the spread of cancer cells to the lungs in mice, paving the way for future targeted cancer therapies.
