عن كتاب Encyclopedia of Physical Science and Technology - Molecular Biology-Elsevier:

immature and autoreactive T cells, Wolffian and Mullerian
duct regression during sexual development, tumor regression, and in elimination of virus-infected cells. Furthermore, it has been suggested that apoptosis occurs in many
diseases such as cancer, fulminant hepatitis, acquired immune deficiency syndrome (AIDS), diabetes mellitus, and
neurodegenerative disorders such as Alzheimer’s disease
and prion disease.
Growth and differentiation of cells are strictly regulated
by factors such as cytokines and low-molecular-weight
compounds such as steroid hormones. These factors are
generally bound to the corresponding receptors in order to
transduce the appropriate cell signals, to promote growth
and differentiation. On the other hand, apoptotic cell death
is aggressively controlled by a number of polypeptides,
so-called death factors exposed at the cell surface or circulating in the body as soluble factors in some situations.
Growth and differentiation factors act via transcriptional
regulation through the activation of a series of protein kinases. On the other hand, death factors execute apoptosis
through the activation of caspases, and many proteins essential for cell survival are degraded by these activated caspases. It is currently believed that apoptotic death is due to
the degradation of many functional proteins by caspases.
Cell-free systems for the study of apoptosis have been
established and facilitate our understanding of the underlying molecular mechanisms. Several factors involved in
apoptotic pathways have been identified and part of these
pathways has been revealed by biochemical approaches
based on cell-free apoptosis system. Regulatory mechanisms for apoptosis include: the CED-3/caspase family
proteases and CED-4/Apaf-1 family which act as executors of apoptosis; CED-9/Bcl-2 family (including antiapoptotic and pro-apoptotic factors) which act as regulators of apoptosis, and many factors which contribute
to apoptotic morphological changes have been identified.
Here, I shall focus on the currently proposed molecular
mechanisms of death receptor activity and caspase activation. Moreover, I will also discuss the DNase responsible
for apoptotic DNA fragmentation, both in vitro and in
vivo, and finally the mechanism by which apoptotic cells
are cleared.
