  WKP
  Definition: Autophagy is the degradation of intracellular components in lysosomes.
  Autophagy is a cellular degradation pathway for the clearance of damaged or superfluous proteins and organelles. The recycling of these intracellular constituents also serves as an alternative energy source during periods of metabolic stress to maintain homeostasis and viability.
  To survive extreme environmental conditions, and in response to certain developmental and pathological situations, (...)

• intermediate filaments-desmosomes interactions

  Pathology
  Proteins that interact with intermediate filaments in desmosome and hemidesmosome cell-junction complexes are associated with several diseases.
  The loss of plectin, a cytoskeletal linker protein with critical functions in keratin organization in skin and desmin organization in muscle sarcomeres, causes the recessive disorder epidermolysis bullosa simplex with muscular dystrophy.
  Disturbances of other desmosomal proteins have been linked to ectodermal dysplasia, hair (...)

• caspase-independent cellular death
  20 April 2004

  Caspase activation has been frequently viewed as synonymous with apoptotic cell death; however, caspases can also contribute to processes that do not culminate in cell demise. Moreover, inhibition of caspases can have cytoprotective effects.
  In a number of different models, caspase inhibition does not maintain cellular viability and instead shifts the morphology of death from apoptosis to nonapoptotic pathways.
