What is Cell Death? Some background
At the level of the cell (like the cells withing your body), there
are really "two ways to go".
Cell death programmes, far from being sinister, are essential
to proper growth and development. In order to make the spaces
between your fingers, for example, certain cells had to die and
be removed during your development.
Apoptosis is particularly interesting to humans because problems
with cell death not going on as planned are implicated in diseases
like Alzheimer's, and because the ability to target and kill cells
selectively would be of great benefit in the treatement of diseases
But before we get too excited about this, does apoptosis occur
in single celled organisms?
But why would a unicellular organism kill itself?
The Bottom Line: We don't know.
