Expansion of a CAG triplet repeat stretch within the Huntingtin gene results in a different (mutant) form of the protein, which gradually damages cells in the brain, through mechanisms that are not fully understood. What is Huntington's Disease? http://www.youtube.com/watch?v=4HgFUvVyHYQ Tourette’s syndrome http://www.youtube.com/watch?v=jYRa-fpNonY Parkinson’s disease http://www.youtube.com/watch?v=wWQoLEKq4Wc Parkinson genes Nature Editor's summaryinالعر Loss-of-function mutations affecting two enzymes involved in the clearance of damaged mitochondria (mitophagy) — the ubiquitin ligase parkin and the protein kinase PINK1 — are associated with familial Parkinson's disease. Here it is shown that USP30, a deubiquitinase localized to mitochondria, antagonizes mitophagy by removing the ubiquitin tags put in place by parkin. Reducing USP30 activity enhances mitochondrial degradation in neurons, and knockdown of USP30 rescues defective mitophagy caused by pathogenic mutations in parkin. Knockdown of USP30 in aDrosophila model improves mitochondrial integrity and survival in both parkin- and PINK1- deficient flies. Thus, USP30 inhibition is potentially beneficial for Parkinson's disease by promoting mitochondrial clearance and quality control. A graphical representation of how cellular health can be affected by changes in the levels of mitophagy — the process by which cells dispose of mitochondria that have become defective or damaged. Insufficient or excessive mitophagy reduces cellular health, owing to accumulation of defective mitochondria or disposal of too many mitochondria, respectively. PINK1–parkin signalling promotes mitophagy, and Bingol et al.1 now find that an enzyme, USP30, opposes the action of the parkin enzyme and inhibits mitophagy (not shown). Thus, in cells that express both parkin and USP30, a balanced level of mitophagy is maintained. Neurofibrillary Tangles (NFTs) are aggregates of hyperphosphorylated tau protein that are most commonly known as a primary marker of Alzheimer's Disease Alzheimer's disease is a synaptic failure DJ Selkoe - Science, 2002 - sciencemag.org Abstract In its earliest clinical phase, Alzheimer's disease characteristically produces a remarkably pure impairment of memory. Mounting evidence suggests that this syndrome begins with subtle alterations of hippocampal synaptic efficacy prior to frank neuronal ... 2197회 인용 관련 학술자료 전체 27개의 버전 Web of Science: 1564 인용 저장 (a) Hypothetical relationship between Aβ level and synaptic activity. Intermediate levels of Aβ enhance synaptic activity presynaptically, whereas abnormally high or low levels of Aβ impair synaptic activity by inducing postsynaptic depression or reducing presynaptic efficacy, respectively. (b) Within a physiological range, small increases in Aβ primarily facilitate presynaptic functions, resulting in synaptic potentiation38, 39. (c) At abnormally high levels, Aβ enhances LTD-related mechanisms, resulting in postsynaptic depression and loss of dendritic spines4, 7, 31, 46.
