Pathological roles of α-synuclein in neurological disorders
Vekrellis K, Xilouri M, Emmanouilidou E, Rideout HJ, Stefanis L.. The Lancet. Neurology, 2011-11-01
Topic: Brain proteins, microglia and lab models
Substantial genetic, neuropathological, and biochemical evidence implicates the presynaptic neuronal protein α-synuclein in Parkinson's disease and related Lewy body disorders. How dysregulation of α-synuclein leads to neurodegeneration is, however, unclear. Soluble oligomeric, but not fully fibrillar, α-synuclein is thought to be toxic. The major neuronal target of aberrant α-synuclein might be the synapse. The effects of aberrant α-synuclein might include alteration of calcium homoeostasis or mitochondrial fragmentation and, in turn, mitochondrial dysfunction, which could link α-synuclein dysfunction to recessive and toxin-induced parkinsonism. α-Synuclein also seems to be linked to other genetic forms of Parkinson's disease, such as those linked to mutations in GBA or LRRK2, possibly through common effects on autophagy and lysosomal function. Finally, α-synuclein is physiologically secreted, and this extracellular form could lead to the spread of pathological accumulations and disease progression. Consequently, factors that regulate the levels, post-translational modifications, specific aberrant cellular effects, or secretion of α-synuclein might be targets for therapy.

Key findings
- Soluble oligomeric, but not fully fibrillar, α-synuclein is thought to be toxic.
- The major neuronal target of aberrant α-synuclein might be the synapse.
- The effects of aberrant α-synuclein might include alteration of calcium homoeostasis or mitochondrial fragmentation and, in turn, mitochondrial dysfunction, which could link α-synuclein dysfunction to recessive and toxin-induced parkinsonism. α-Synuclein also seems to be linked to other genetic forms of Parkinson's disease, such as those linked to mutations in GBA or LRRK2, possibly through common effects on autophagy and lysosomal function.
- Finally, α-synuclein is physiologically secreted, and this extracellular form could lead to the spread of pathological accumulations and disease progression.
- Consequently, factors that regulate the levels, post-translational modifications, specific aberrant cellular effects, or secretion of α-synuclein might be targets for therapy.
Study details

How this study scored 40/100
Published in a leading specialty journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 23 of the 58 points we could judge it on, which is 40 out of 100.
