New evidence shows cytotoxic T cells can identify, invade, and destroy targets of large mass like T. gondii tissue cysts

CD8+ cytotoxic T lymphocytes can kill host cells infected with various microorganisms as well as single individual cancer cells through direct cell-to-cell contact, but their ability to destroy a target of large mass remains unexplored. A study in The American Journal of Pathology provided novel evidence on the capability of the immune system to eliminate large parasite-filled cysts associated with chronic Toxoplasma gondii (T. gondii) infection by utilizing the aggressive invader activity of cytotoxic T cells. They may also prove effective for attacking other sizable targets including solid cancers.
