Multicatalytic proteinase is present in Lewy bodies and neurofibrillary tangles in diffuse Lewy body disease brains.
A non-lysosomal multicatalytic proteinase (MCP) is immunohistochemically visualized in Lewy bodies and loosely arranged globose tangles but not in the majority of compact neurofibrillary tangles in brains with cortical diffuse Lewy body disease. Virtually all Lewy bodies are immunoreactive to MCP, exhibiting various staining patterns where they are moderately diffuse, intense in the central core or intense in the peripheral rim. MCP may be involved in the formation of these inclusions.
