Other authors hypothesized that formation of aggregated proteins might be a protective strategy of the aging neurons [ 13 ]. Protein aggregation is regarded as a side reaction of folding. Based on the results of apoE and lipid experiments, novel methods are offered: Very recent studies have characterized the genetic networks associated with AD from large sampling of postmortem brain tissues [ ]. Different cellular stress conditions result in the up-regulation of the neurotrophic, neuroprotective amyloid precursor protein APP. Aging is the key risk factor, as the capacity of the proteostasis network declines during aging. Aggregation-prone proteins are constitutively expressed in the cell, creating a chronic stress situation. The precise molecular mechanism of the conversion of a non-transmissible protein molecule to the pathogenic form e.

    Multiple alternate pathways exist for APP proteolysis, some of which lead to containing protein (p97) in Alzheimer's disease: a novel link to dysfunction in. These findings may suggest that a dysregulated splicing of APP RNA . pathways and has also been found to affect APP processing. Keywords: Alzheimer's disease, APP, Aβ, post-translational modifications, trafficking familial AD due to the dysregulation of Aβ generation (Deng et al., ;. Along the secretory pathway, BACE1 undergoes a series of.
    Lysosomal pH is acidic and defective lysosomal acidification might cause autophagy failure and thus AD [ ].

    Molecular pathological classification of neurodegenerative diseases is based on the presence of these pathologically altered, misfolded proteins in the brain as deposits [ 4 ]. Aggregation-prone proteins play important roles in the onset of NDDs. It is almost forgotten that at the beginning of the eighties-nineties, AD was suspected of being a prion disease [ 69 ].

    With aging and even more so in AD the reabsorption of CSF back into the circulation is reduced [ ]. Recognition of the above mentioned complex pathogenesis pathway resulted in novel drug targets in AD research.

    Studies on APP overexpression demonstrate that it positively modulates cell survival and growth [ 21 ].

    LOAD is a polygenic disease, and thus also environmental factors are needed for its manifestation beyond the genetic background. Very recent results show that pathophysiological changes begin many years before clinical manifestation of AD and the disease is a multifaceted process [ 17 ].

    Alzheimer's Disease (AD) is the most prevalent non-reversible Amyloid precursor protein (APP) is the substrate for β-secretase and uncontrolled . As studies suggested, the positive association of Wnt pathway with AD.

    Mitochondria play a key role in energy metabolism, their role in aging and AD pathogenesis has been emphasized for years.

    Prevention strategies [] and new AD-drug targets have been outlined with this aim [, ]: A number of radically new approaches for targeting key stages in AD pathogeneses were proposed and gave hope for successful development of novel therapeutics for AD treatments. All the APP family members are truly multifunctional proteins and can form large signaling complexes with various transmembrane proteins and intracellular binding partners [ 40 ].

    Other authors hypothesized that formation of aggregated proteins might be a protective strategy of the aging neurons [ 13 ]. Acute stroke, cardiac arrest or chronic cerebrovascular disease hypoxic-ischemic conditions cause up-regulation of APP. The term protein homeostasis proteostasis refers to the maintenance of all proteins in the proteome in a conformation, concentration and location that is required for their correct functions [ ].

    Microglia regularly monitor their environment and regulate tissue homeostasis through the scavenging functions.

    Mutations of genes regulating autophagy cause NDDs, such as AD, across the age spectrum with exceptional frequency [ ]. Theoretically, all PMDs have the intrinsic potential to be transmissible [ 8690 ].
