The recent discovery that brain PGP 9.5 is a ubiquitin carboxyl-terminal hydrolase suggests that the role of this protein should be studied in relation to ubiquitinated cellular inclusions characteristic of several chronic human degenerative diseases. Formalin-fixed, paraffin-processed sections known to contain ubiquitin-protein conjugate immunoreactivity(More)
MS73 is one of a family of ATPases that act as regulatory subunits of the 26S proteasome. Localisation of this ATPase in histological sections of hippocampus from Alzheimer's disease (AD) and in cingulate gyrus sections of dementia with Lewy bodies (DLB) brains was examined immunohistochemically. In all cases of AD (n = 10) neurofibrillary tangles (NFT),(More)
In Alzheimer's disease (AD) neurofibrillary tangles (NFT) are strongly tau and ubiquitin immunopositive, and contain an aberrant form of ubiquitin derived from the ubiquitin-B gene denoted as UBB+1. We explored whether the tau-related NFT seen in another neurodegenerative disease, progressive supranuclear palsy (PSP), also showed an accumulation of UBB+1.(More)
In a recent preliminary study it was reported that a severe head injury resulted in the deposition of beta amyloid protein (beta AP) in the cortical ribbon of 30% of patients who survived for less than two weeks. Multiple cortical areas have now been examined from 152 patients (age range 8 weeks-81 years) after a severe head injury with a survival time of(More)
Diffuse Lewy body disease is an important pathological substrate of the common syndrome of parkinsonian dementia. The new technique of anti-ubiquitin immunocytochemistry has been used in a correlative quantitative neuropathological study of fifteen cases of diffuse Lewy body disease, showing that the severity of dementia is related to cortical Lewy body(More)
The localisation of 14-3-3 proteins compared to that of tau and ubiquitin-protein conjugates in sections of hippocampus from Alzheimer's disease (AD) brains was examined by immunohistochemistry. In all cases (n = 10), anti-14-3-3 stained a proportion of neurofibrillary tangles (NFT). In general, NFT stained by anti-14-3-3 were smaller than those stained by(More)
Brainstem and cortical Lewy bodies in diffuse Lewy body disease show intense immunoreactivity to antibodies against ubiquitin. Quantitative studies show that the novel neuropathological technique of anti-ubiquitin immunocytochemistry is more than twice as sensitive as conventional haematoxylin and eosin stains in detecting cortical Lewy bodies.(More)
alpha B crystallin is a protein which has homology with the small cell stress proteins. A characterized antibody to residues 1-10 of alpha B crystallin was used to immunostain tissues containing ballooned (chromatolytic, achromasic) neurons. The tissues included two cases of classical Pick's disease, one case of dementia with swollen achromasic neurons in(More)
Using an immunocytochemical method to localise antibodies to ubiquitin, filamentous inclusion bodies were seen in spinal anterior horn neurones in cases of motor neurone disease (MND) but not in any control cases. These inclusion bodies appeared to be closely associated with classical Bunina bodies and immuno-electron microscopy suggested that they were(More)
