AUTODESTRUCTION. “In response to stress due to starvation or damage, animal cells engage a biochemical pathway to destruct themselves. Moreover, upon detection of a virally infected cell, cytotoxic cells kill other cells from the same organism by inducing their suicide. Cell death is not only employed to remove damaged or infected cells, but it is also important for sculpting tissues.”
