The plaques formed by amyloid-β (Aβ) accumulation and neurofibrillary tangles formed by hyper-phosphorylated tau protein are the 2 major pathologies of Alzheimer's disease (AD). Recently, autophagy is considered to be a self-degradation process of preserved cytoplasmic abnormal substances, including Aβ and tau.

Intracellular accumulation of amyloid-β protein (Aβ) is an early event in Alzheimer's disease (AD). The autophagy-lysosomal pathway is an important pathway for maintaining cellular proteostasis and ...
We explored the potential for autophagy to regulate budding yeast meiosis. Following pre-meiotic DNA replication, we blocked autophagy by chemical inhibition of Atg1 kinase or engineered degradation o...
Pioglitazone (Pio), a peroxisome proliferators-activated receptor-γ (PPAR-γ) agonist, may protect against renal ischemia/reperfusion injury (IRI). Recent studies have shown that autophagy plays a pr...
Autophagy has been demonstrated to be vital for kidney homeostasis and is centrally implicated in the pathogenesis of cisplatin-induced acute kidney injury (AKI). Lithium is a potent autophagy inducer...
Leucine, nutrient signal and substrate for the branched chain aminotransferase (BCAT) activates the mechanistic target of rapamycin (mTORC1) and regulates autophagic flux, mechanisms implicated in the...
The purpose of this study is to measure cerebrospinal fluid (CSF) clearance. CSF cushions the brain from impact and carries waste products from the brain to the bloodstream. This process i...
Normal cells primarily produce energy with the help of the "mitochondria". These "small organs" are also called the "powerhouses of the cell" turn the sugars, fats and proteins that we eat...
Alzheimer's Disease (AD) is characterized by amyloid-β (Aβ) plaque buildup and phosphorylated tau (p-tau) in the brain, as well as widespread neurodegeneration. The evidence suggests that ...
Little is known about autophagy during HIV infection. Recently, two different teams reported important dysfunctions of autophagy in HIV-infected patients despite sustained suppressive anti...
To investigate the effects of different dietary regimens on muscle wasting, insulin/IGF-1 resistance. Further, to explore whether LPD+KA decrease the activation of autophagy associate with...
A type of extracellularly deposited substance composed of an amyloid protein and additional components including HEPARAN SULFATE PROTEOGLYCAN; LAMININ; COLLAGEN TYPE IV; SERUM AMYLOID P-COMPONENT; and APOLIPOPROTEINS E which together form characteristic amyloid fibrils. The core of amyloid fibrils is formed by the stacking of overlapping beta-pleated sheet domains of the amyloid protein. There are many different amyloid proteins that have been found forming the core of the fibrils in vivo. However, amyloid can be formed from any protein that exposes beta-pleated strand conformations during unfolding or refolding. A common characteristic of amyloid is the ability to bind such dyes as CONGO RED and thioflavine.
Proteins that form the core of amyloid fibrils. For example, the core of amyloid A is formed from amyloid A protein, also known as serum amyloid A protein or SAA protein.
Peptides generated from AMYLOID BETA-PEPTIDES PRECURSOR. An amyloid fibrillar form of these peptides is the major component of amyloid plaques found in individuals with Alzheimer's disease and in aged individuals with trisomy 21 (DOWN SYNDROME). The peptide is found predominantly in the nervous system, but there have been reports of its presence in non-neural tissue.
A pancreatic beta-cell hormone that is co-secreted with INSULIN. It displays an anorectic effect on nutrient metabolism by inhibiting gastric acid secretion, gastric emptying and postprandial GLUCAGON secretion. Islet amyloid polypeptide can fold into AMYLOID FIBRILS that have been found as a major constituent of pancreatic AMYLOID DEPOSITS.
Amyloid P component is a small, non-fibrillar glycoprotein found in normal serum and in all amyloid deposits. It has a pentagonal (pentaxin) structure. It is an acute phase protein, modulates immunologic responses, inhibits ELASTASE, and has been suggested as an indicator of LIVER DISEASE.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
