Immunology Today, 1993
Cell death can be accidental or programmed in a multicellular organism. Evidence supports the proposition that there is a 'suicide program' inherent in vertebrate cells which can be activated when the cell's death is desirable for the good of the rest of the community.

Mechanisms of Ageing and Development, 1998
Stimulation of T cells from aged individuals leads to different kinds and/or size of responses if compared with the responses of T cells obtained from young individuals. In fact elderly is associated with a progressive decline of immune response besides an increasing incidence of autoimmune phenomena.

Apoptosis, 1999
In addition to its role as a mediator of innate pro-inflammatory responses following bacterial lipopolysaccharide (LPS) binding, the 55kDa glycosyl-phosphatidylinositol-linked macrophage plasma membrane glycoprotein CD14 is now also known to play a role in phagocytic clearance of apoptotic cells.

Apoptosis and aging: breast cells and apoptosis
Maturitas, 2001The major events involved in tissue homeostasis are proliferation, differentiation and apoptosis. Senescence is a non-dividing state of the cell, usually associated with terminal differentiation, and preceding cell death. The three pathways result in suppression of cell proliferation. Apoptosis during aging can contribute to the elimination of damaged,

Cytokine & Growth Factor Reviews, 2002
Apoptosis in mammalian cells can be initiated through two major interrelated pathways, one involving engagement of the TNF family of death receptors, the other involving the release of cytochrome c from mitochondria. Unlike other members of the TNF ligand family, TNF-related apoptosis-inducing ligand (TRAIL) preferentially induces apoptosis in tumor ...

Publisher Summary The genetic analysis of apoptosis, or programmed cell death, provides important information on the biology of naturally occurring cell death. Identification of genes regulating apoptosis has confirmed that this process follows a similar paradigm in all multicellular organisms.

Biochemistry and Cell Biology, 2000
Here we review the different apoptotic DNases. From a functional point of view, DNases implicated in apoptosis may be classified into three groups: the Ca2+/Mg2+ endonucleases, the Mg2+-endonucleases, and the cation-independent endonucleases. The first group includes DNase I which has no specificity for the linker region, DNase gamma which has some ...

Apoptosis, 2001
Infection with the human immunodeficiency virus type 1 (HIV-1) leads to progressive immunodeficiency and onset of opportunistic infections and neoplasms. The loss of immune competence is associated with declines in both the functionality and the number of CD4+ lymphocytes.

The American Journal of Medicine, 2000
During normal bone remodeling, the rate of supply of new osteoblasts and osteoclasts and the timing of the death of osteoclasts, osteoblasts, and osteocytes by apoptosis are critical determinants of the initiation of new BMUs and the extension or reduction of the lifetime of existing ones.

Journal of Leukocyte Biology, 1995
Abstract All cells of the hematopoietic system have finite life spans, shorter by far than that of the host. They end their lives by committing a form of cellular suicide or programmed cell death. The morphology of this process is considerably different from that of necrosis and is called apoptosis.
