  23 April 2004

  WKP
  Definition: Phagocytosis is a specific form of endocytosis involving the vesicular internalization of solid particles, such as bacteria. It is therefore distinct from other forms of endocytosis such as pinocytosis, the vesicular internalization of various liquids, and recptor-dependent endocytosis.
  Phagocytosis involves three distinct but interrelated steps:
  (1) recognition and attachment of the particle to be ingested by the leukocyte;
  (2) its engulfment, with subsequent (...)

• cellular aging
  7 March 2004

  Cellular aging is the result of a progressive decline in the proliferative capacity and life span of cells and the effects of continuous exposure to exogenous influences that result in the progressive accumulation of cellular and molecular damage. Structural and Biochemical Changes with Cellular Aging
  A number of cell functions decline progressively with age.
  Oxidative phosphorylation by mitochondria is reduced, as is synthesis of nucleic acids and structural and enzymatic proteins, (...)

  cell death; cellular death WKP
  Definition : Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, or may result from such factors as disease, localized injury, or the death of the organism of which the cells are part.
  Apoptosis or Type I cell-death, and autophagy or Type II cell-death are both forms of programmed cell death, while necrosis is a (...)

• cytokinesis
  15 September 2003

  Process by which the daugther cells separate from each other at the end of the cellular division
  Cytokinesis follows nuclear division and generates two distinct daughter cells, each replete with a full complement of the genome and cytoplasmic organelles.
  Completion of cell division during cytokinesis requires temporally and spatially regulated communication from the microtubule cytoskeleton to the actin cytoskeleton and the cell membrane.
  Exit from the cytokinetic phase of the cell cycle (...)
