Alpha Synuclein Antibody ~ Definition, Overview & Research Papers of Alpha Synuclein Antibody ~ Synuclein Blog
α-Synuclein is a protein of 140-amino acids expressed abundantly in the brain. α-synuclein is also the main component of pathogenic Lewy bodies and Lewy neurites. Mutations of the α-synuclein gene have been linked to Parkinson disease (1). Goldberg, M.S. and Lansbury Jr., P.T. (2000) Nat. Cell Biol. 2, 115-119.

This antibody recognizes the 19 kDa protein, a-synuclein, which belongs to a family of small cytoplasmic proteins expressed predominantly in neurons. The epitope maps to amino acid residues 121-125 of human a-synuclein. a-synuclein may bee involved in neuronal plasticity and could act as a molecular chaperone that mediates the transformation of soluble Aß intto insoluble amyloid. The protein is a major component of Lewy bodies, the pathological hallmark of Parkinson’s disease, and is also observed in senile plaques of Alzheimer’s disease patients. Human a-synuclein appears to be phosphorylated at two major sites, serine 129 and serine 87, and phosphorylation may play a role in the functional regulation of the protein. http://www.pierce-antibodies.com/Anti-alpha-Synuclein-antibody-clone-Syn-211-Monoclonal--MA112874.html

Abstract

Immunohistochemistry for alpha-synuclein has become the histological technique of choice for the diagnosis for Parkinson's disease, Dementia with Lewy bodies and Multiple System Atrophy (http://www.ICDNS.org). Nevertheless, no standardised protocol has been proposed. We have reviewed 242 of the 270 studies published until June 2005 that mentioned immunohistochemistry for anti-alpha synuclein on human tissue and we found that only 75 (31%) used commercial antibodies. We also noted that protocols, particularly dilution and antigen unmasking, varied between studies, even when the same antibody was employed. In order to establish a standardised protocol for alpha-synuclein immunohistochemistry, which can be applied in diagnostic neuropathology we tested seven commercial monoclonal antibodies in brains of subjects with Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, multiple sclerosis with incidental Lewy bodies and aged-matched normal brain and determined for each antibody the best suited protocol for antigen unmasking. We evaluated the intensity of immunolabelling in Lewy bodies, neuropil threads, dendrites, pre-synaptic terminals, granular cytoplasmic positivity, peri-axonal positivity, glial inclusions and non-specific immunolabelling. Although our results showed that all the antibodies detected alpha-synuclein inclusions, differences were noted between antibodies, particularly with regard to the detection of glial inclusions. From our study, the best antibodies of the seven tested appeared to be those directed against amino acids 116-131 and 15-123 and we suggest them to be used in routine diagnostic practice for alpha-synucleinopathies. http://www.ncbi.nlm.nih.gov/pubmed/16640654
Antibodies against alpha-synuclein have replaced antibodies against ubiquitin as the gold standard for immunostaining of Lewy bodies. Certain sections of the alpha-synuclein protein may play a role in the tauopathies. http://en.wikipedia.org/wiki/Alpha-synuclein


Events in α-synuclein toxicity. The central panel shows the major pathway for protein aggregation. Monomeric α-synuclein is natively unfolded in solution but can also bind to membranes in an α-helical form. It seems likely that these two species exist in equilibrium within the cell, although this is unproven. From in vitro work, it is clear that unfolded monomer can aggregate first into small oligomeric species that can be stabilized by β-sheet-like interactions and then into higher molecular weight insoluble fibrils. In a cellular context, there is some evidence that the presence of lipids can promote oligomer formation: α-synuclein can also form annular, pore-like structures that interact with membranes. The deposition of α-synuclein into pathological structures such as Lewy bodies is probably a late event that occurs in some neurons. On the left hand side are some of the known modifiers of this process. Electrical activity in neurons changes the association of α-synuclein with vesicles and may also stimulate polo-like kinase 2 (PLK2), which has been shown to phosphorylate α-synuclein at Ser129. Other kinases have also been proposed to be involved. As well as phosphorylation, truncation through proteases such as calpains, and nitration, probably through nitric oxide (NO) or other reactive nitrogen species that are present during inflammation, all modify synuclein such that it has a higher tendency to aggregate. The addition of ubiquitin (shown as a black spot) to Lewy bodies is probably a secondary process to deposition. On the right are some of the proposed cellular targets for α-synuclein mediated toxicity, which include (from top to bottom) ER-golgi transport, synaptic vesicles, mitochondria and lysosomes and other proteolytic machinery. In each of these cases, it is proposed that α-synuclein has detrimental effects, listed below each arrow, although at this time it is not clear if any of these are either necessary or sufficient for toxicity in neurons.
