Neurotoxic alterations of a-synuclein that lead to the formation of toxic oligomers and fibrils contribute to PD through synaptic dysfunction, mitochondrial impairment, defective endoplasmic reticulum and Golgi function, and nuclear dysfunction. In half of the cases, the recessively inherited early-onset PD is caused by loss of function mutations in the PARK2 gene that encodes the E3-ubiquitin ligase, parkin. Parkin is involved in the clearance of misfolded and aggregated proteins by the ubiquitin-proteasome system and regulates mitophagy and mitochondrial biogenesis. PARK2-related PD is generally thought not to be associated with Lewy body formation although it is a neuropathological hallmark of PD. In this review article, we provide an overview of post-mortem neuropathological examinations of PARK2 patients and present the current knowledge of a functional interaction between parkin and a-synuclein in the regulation of protein aggregates including Lewy bodies.

Downloaded from Journal of Neurology, Neurosurgery, and Psychiatry 1988;51:745-752 Occasional review The relevance of the Lewy body to the pathogenesis of idiopathic Parkinson's disease W R G GIBB, A J LEES From the Department ofNeuropathology, National Hospitalsfor Nervous Diseases, Maida Vale, London, UK SUMMARY The Lewy body is a distinctive neuronal inclusion that is always found in the substantia nigra and other specific brain regions in Parkinson's disease. It is mainly composed of structurally altered neurofilament, and occurs wherever there is excessive loss of neurons. It occurs in some elderly individuals and rarely in other degenerative diseases of the central nervous system. In 273 brains of patients dying from disorders other than Parkinson's disease, the age-specific prevalence of Lewy bodies increased from 3-8% to 12-8% between the sixth and ninth decades. Associated pathological findings suggest that these cases of incidental Lewy body disease are presymptomatic cases of Parkinson's disease, and confirm the importance of age (time) in the evolution of the Protected by copyright. disease. In view of the common and widespread occurrence of this disorder we propose that endo- genous mechanisms operating in early life may be more important than environmental agents in the pathogenesis of Lewy bodies and Parkinson's disease.

In LBD, neuropathologic criteria defined Lewy body α-synuclein (SYN) stages with medium/high AD copathology (SYN + AD = 10) and low/no AD copathology (SYN − AD = 14). Ordinal pathology scores for tau, β-amyloid (Aβ), and SYN pathology were averaged across 7 cortical regions to obtain a global cerebral score for each pathology. CSF total tau (t-tau), phosphorylated tau at thre- β onine181, and A 1-42 levels were compared between LBD and control groups and correlated with global cerebral pathology scores in LBD with linear regression. Diagnostic accuracy for postmortem categorization of LBD into SYN + AD vs SYN − AD or neocortical vs brainstem/ limbic SYN stage was tested with receiver operating curves.

  • Lewy Body Dementia: Putting the Puzzle Pieces Together When The
    Lewy Body Dementia: Putting the Puzzle Pieces Together When the world first heard that Robin Williams committed suicide, most people were shocked. After the release of his final medical autopsy report that showed he had advanced Lewy Body Dementia: his suicide became more understandable. His mind was very sick, and his prognosis was not good. When we look at all the facts and observations about Lewy Bodies, we are presented with a puzzle that just doesn’t make sense. How do Lewy Bodies form? Why are some Lewy bodies located inside brain-neurons? While other Lewy Bodies float in the extracellular spaces between brain cells? Why are they observably different? Why do Lewy Bodies predominate in Parkinson’s regions of the brain like the Substantia Nigra, but can also be seen in the hippocampus, the temporal lobes, the basal forebrain and the neo-cortex? Lewy Bodies contain two common brain proteins Ubiquitin and Alpha Synuclein, but modifying proteins inside the neuron and chaperone proteins alter these two completely normal brain proteins, and the two proteins recombine in a way that is toxic to neurons. Alpha-Synuclein forms structured fibrils. The protein went from an amorphous flexible unstructured state to an organized rigid structure that forms fibrils. Traditional Lewy Body research points out the observed facts, but no Lewy Body researcher has ever answered the question: Why do Lewy Bodies form? Until the last six months no one had any new theories, but I am going to suggest something radical based on new observations and data from the work done at the Dr.

  • Alpha-Synuclein Biology in Lewy Body Diseases Woojin Scott Kim1,2*, Katarina Kågedal3 and Glenda M Halliday1,2
    Kim et al. Alzheimer's Research & Therapy 2014, 6:73 http://alzres.com/content/6/5/73 REVIEW Alpha-synuclein biology in Lewy body diseases Woojin Scott Kim1,2*, Katarina Kågedal3 and Glenda M Halliday1,2 Abstract α-Synuclein is an abundantly expressed neuronal protein that is at the center of focus in understanding a group of neurodegenerative disorders called α-synucleinopathies, which are characterized by the presence of aggregated α-synuclein intracellularly. Primary α-synucleinopathies include Parkinson’s disease (PD), dementia with Lewy bodies and multiple system atrophy, with α-synuclein also found secondarily in a number of other diseases, including Alzheimer’s disease. Understanding how α-synuclein aggregates form in these different disorders is important for the understanding of its pathogenesis in Lewy body diseases. PD is the most prevalent of the α-synucleinopathies and much of the initial research on α-synuclein Lewy body pathology was based on PD but is also relevant to Lewy bodies in other diseases (dementia with Lewy bodies and Alzheimer’s disease). Polymorphism and mutation studies of SNCA, the gene that encodes α-synuclein, provide much evidence for a causal link between α-synuclein and PD. Among the primary α-synucleinopathies, multiple system atrophy is unique in that α-synuclein deposition occurs in oligodendrocytes rather than neurons. It is unclear whether α-synuclein originates from oligodendrocytes or whether it is transmitted somehow from neurons. α-Synuclein exists as a natively unfolded monomer in the cytosol, but in the presence of lipid membranes it is thought to undergo a conformational change to a folded α-helical secondary structure that is prone to forming dimers and oligomers.
