Results will provide insights into how human-modified environments shape natural process such as: endothelial cell senescence and apoptosis (miR-34a),
Cell death is a finely tuned programme inherent in the cells genetic machinery. This normal cell death which is the part of normal development and maintenance of homeostasis is called apoptosis or programmed cell death (PCD). This phenomenon is very much different from death of a cell due to pathological cause or necrosis.
Its role in both immune development and the control of immune responses as well as in T cell cytotoxic effector function has been established. Apoptosis, known as programmed cell death, is a carefully controlled, energy-dependent process of cell death. Induction of apoptosis results in a cascade of characteristic biochemical events resulting in changes in cellular morphology and death. Cells undergoing apoptosis display blebbing, cell shrinkage, nuclear fragmentation, and DNA fragmentation. Apoptosis, also called programmed cell death, in biology, a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger.

This is an active cell death process Programmed Cell Death. Apoptosis Human neutrophils are constantly produced in the marrow and released into the blood to search for invading pathogens. APOPTOSIS • Programmed cell death • Specific biochemical signature (ex. phosphatidylserine.
Cell death is the biological process in which cells stop functioning due to the process meets all critical criteria: the results are apoptosis-specific, integrative,
Unlike cellular death caused by injury, apoptosis results in cell shrinkage and fragmentation. This allows the cells to be efficiently phagocytosed and their components reused without releasing potentially harmful intracellular substances (such as hydrolytic enzymes, for example) into the surrounding tissue.
1 Apoptosis is the cellular equivalent of a “self destruct” button. of specialized enzymes (caspases and others) that directly result in cell death.3 Further in lethal doses within each cell, but they only become active via the in
Induction of apoptosis results in a cascade of characteristic biochemical events resulting in changes in cellular morphology and death. Cells undergoing apoptosis display blebbing, cell shrinkage, nuclear fragmentation, and DNA fragmentation. Apoptosis, also called programmed cell death, in biology, a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger. Apoptosis can be triggered by mild cellular injury and by various factors internal or external to the cell; the damaged cells are then disposed of in an orderly fashion. Apoptosis is a process of programmed cell death that occurs in multicellular organisms. It is a highly regulated and controlled process that occurs normally during development and aging as a homeostatic mechanism to maintain cell populations in tissues [1].

Apoptosis is described as an active, programmed process of autonomous cellular dismantling that avoids eliciting inflammation. Necrosis has been characterized as passive, accidental cell death resulting from environmental perturbations with uncontrolled release of inflammatory cellular contents.
The term apoptosis, from Greek origins (apo=for, ptosis=falling), was chosen to describe the cellular process of programmed cell death. 1-3 Apoptosis is a tightly regulated intracellular program in which cells destined to die activate enzymes that degrade the cell's DNA and nuclear and cytoplasmic proteins. 4 Programmed cell death eliminates unwanted cells or potentially reactive cell lines of determining cell death.
