Apoptosis (from Ancient Greek: ἀπόπτωσις, romanized: apóptōsis, lit. 'falling off') is a form of programmed cell death that occurs in multicellular organisms and in some eukaryotic, single-celled microorganisms such as yeast. [1] Biochemical events lead to …

2024年9月13日 · Apoptosis is a type of programmed cell death that rids your body of damaged cells. Too little or too much apoptosis can cause issues like cancer or Alzheimer’s.

2017年6月6日 · Apoptosis is a process that occurs in multicellular when a cell intentionally “decides” to die. This often occurs for the greater good of the whole organism, such as when the cell's DNA has become damaged and it may become cancerous.

2025年3月8日 · Apoptosis, 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 …

The process of programmed cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy-dependent biochemical mechanisms. Apoptosis is considered a vital component of various processes including normal ...

In multicellular organisms, cells that are no longer needed or are a threat to the organism are destroyed by a tightly regulated cell suicide process known as programmed cell death, or apoptosis. Apoptosis is mediated by proteolytic enzymes called caspases, which trigger cell death by cleaving specific proteins in the cytoplasm and nucleus.

Apoptosis is an essential process regarding tissue homeostasis, and it eliminates superfluous cells in multicellular organisms. Several signaling pathways contribute to apoptosis, with the intrinsic (mitochondrial) and extrinsic (death receptor) pathways being the main ones.

3 天之前 · Apoptosis is the process of programmed cell death. It is used during early development to eliminate unwanted cells; for example, those between the fingers of a developing hand. In adults, apoptosis is used to rid the body of cells that have been damaged beyond repair.

2024年4月30日 · This topic highlights the physiological process of apoptosis from the cellular to the systemic level, with clinical correlations to pathological conditions, incorporating current evidence-based literature. The mechanisms of apoptosis are differentiated from necroptosis, pyroptosis, and ferroptosis.

Apoptosis is a biological process which occurs in all multicellular organisms including plants and animals. It removes the cells from the organisms that should no longer be a part of the organism. This process plays a major role in the development of humans and in developing and maintaining a healthy immune system.
