Cancer-killing cells are caught on film in more 3-D detail than ever before

Scientists reveal in more detail than ever before how white blood cells kill diseased tissue using deadly granules. The researchers used 'optical' laser tweezers and a super-resolution microscope to see the inner workings of white blood cells at the highest resolution ever. The researchers describe how a white blood cell rearranges its scaffolding of actin proteins on the inside of its membrane, to create a hole through which it delivers deadly enzyme-filled granules to kill diseased tissue.
