• phagocytosis
  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 (...)

• genomic stability
  13 July 2003

  A fundamental axiom of genetic inheritance is a requirement for exceptional genetic stability over many generations of cells and organisms. However, cells have to contend with both intracellular and extracellular environments that constantly challenge the chemical stability of the genome.
  Additionally, although normal metabolic transactions of DNA such as replication, recombination and repair are generally highly accurate, there are limits to the fidelity of these processes, so genomic (...)

• neutrophil phagocytosis
  14 March 2007

  Phagocytosis of microbes by professional phagocytes such as neutrophils is crucial for the survival of the host.
  Microscopically, pseudopod extension, particulate engulfment and phagosome closure all require seemingly large expansions of the cell surface area.
