The perforin-granzyme pathway involves
A) the production of fever, which kills the pathogen.
B) the production of antibodies toward the invading pathogen.
C) the production of special cell-killing proteins that act on infected or abnormal cells.
D) presenting the foreign antigen to B cells.
E) binding CD95L to infected cells, which eventually leads to cell apoptosis.

Question

Quizplus · Accepted Answer

The perforin-granzyme pathway involves the production and release of special cell-killing proteins called perforin and granzyme, which act on infected or abnormal cells to induce apoptosis (cell death). This is an important mechanism for eliminating virus-infected or cancerous cells from the body. The other choices (A, B, D, and E) are not directly related to the perforin-granzyme pathway.
