A killer T cell takes down a cancer cell in a microscopic showdown 💥🦠 Watch as this powerful immune cell (yellow) targets a cancer cell (magenta) under the microscope. Each strike triggers a signal inside the cancer cell — but it takes several precise hits to bring it down. This real-time footage helps researchers understand how cancer cells resist immune attacks and how we can boost the immune system to fight more effectively. #tcellattack #cancerresearch #microscopicbattle #immuneresponse #k
