PrPC and the Extracellular Matrix PrPC binds two extracellular matrix proteins, laminin and vitronectin, in addition to its interaction with glycosaminoglycans (Fig 1.3) Laminin is an extracellular heterotrimeric 800 kDa glycoprotein involved in cell proliferation, differentiation, migration, and death (Beck Hunter, Engel 1990) PrPC is a saturable and high-affinity, specific receptor for laminin This... phase of this disease The average incubation time of 5 years is associated with the risk of contaminated cattle being used for human consumption for a prolonged duration before the appearance of any clinical signs Other animal species can also be affected by transmissible spongiform encephalopathies (TSEs) Domestic cats and large captive felines have been found with transmissible feline encephalopathy . w0 h0" alt="" NEUROVASCULAR MEDICINE This page intentionally left blank Neurovascular Medicine Pursuing Cellular Longevity for Healthy Aging Kenneth Maiese, MD Division of Cellular and Molecular. degenerative disorders.
