Leukocytes were given weapons to fight metastases

Leukocytes coated with nanoliposomes with two proteins, one of which attaches them to the leukocytes themselves and to cancer cells, and the second causes apoptosis in the cells, destroy tumor cells circulating in the bloodstream – sources of metastases.
