Apoptosis: Programmed Cell Death

We've touched on apoptosis before, especially when we learned about cancer in the biochemistry series. But let's a closer look. We know that apoptosis is programmed cell death, a failsafe mechanism whereby faulty cells that pose a threat to an organism can be systematically destroyed. How does this work? Where do the signals come from and how do they propagate? What kinds of proteins are involved in carrying out this activity? Come and see!
