• collagen
  13 May

  Definition : Collagen is the most common protein in the animal world, providing the extracellular framework for all multicellular organisms.
  The collagens are composed of a triple helix of three polypeptide α chains, having a gly-x-y repeating sequence. Currently 27 different types of collagens encoded by 41 genes ( COLs ) dispersed on at least 14 chromosomes are known.

• infectious agents in histiocytes
  6 May

  The presence of an infections agent in the cytoplasm of histiocytes makes the diagnosis of an infections disease with histiocytic reation.
  For example :
  AARB with Ziehl : mycobacterosis as tuberculoses or lepra
  deep fungal diseases as histoplasmosis
