[Perforin and granzyme--the perfect material of biologic missile].

Perforin and granzyme are important effector molecules in cytolytic cells. They can induce apoptosis of tumor cells and infection cells. The research of biologic missile is noticed with the progress in therapy targeting to the disease. It is supposed that perforin and granzyme play an important role in biological missiles because of their biologic function and structure. A review on several aspects of these effector molecules is presented.
