  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, (...)

• antigen cross-presentation
  5 July 2004

  The ability to process microbial antigens and present them at the surface of cells is an important aspect of our innate ability to clear infections.
  It is generally accepted that antigens in the cytoplasm are loaded in the endoplasmic reticulum and presented at the cell surface on major histocompatibility complex (MHC) class I molecules, whereas peptides present in endo/phagocytic compartments are presented on MHC class II molecules.
  Despite the apparent segregation of the class I and (...)
