title: Lysosomal proteinases as putative diagnostic tools in human neuropathology: Alzheimer disease (AD) and schizophrenia.
abstract: The cathepsin B, D and L were studied by immunohistochemical techniques in the human postmortem brain. The enzyme were primarily localized in neurons. Makroglial cells were seldom immunostained. It is shown that cathepsins B and D frequently occur in neuritic plaques of Alzheimer victims, thereby raising the question, whether or not cathepsin immunohistochemistry is a useful tool in the diagnosis of this disease. Furthermore, we identified certain glial cells to be immunoreactive for cathepsins in schizophrenics.
