Members of the MARK subfamily of the CaMK protein kinases phosphorylate microtubuleassociated proteins tau, MAP2, and MAP4 which are involved in the regulation of the cytoskeleton and the microtubule-based transport by motor proteins of the kinesin family [1]. Hyperphosphorylation of neuronal tau by MARK is a potential cause for the aggregation of tau and the formation of paired helical filamen...
Phosphorylation of tau protein is a critical event in the pathogenesis of Alzheimer's disease (AD). Increased phosphorylated tau and total tau levels, combined with reduced concentrations of amyloid-β 1-42 (Aβ42) in cerebrospinal fluid (CSF), but not in plasma or serum, have been generally accepted as sensitive AD diagnostic markers. However, obtaining CSF is a relatively invasive procedure tha...
BACKGROUND Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder with a complex physiopathology and still undefined initiators. Several risk factors have been suggested for AD with recent evidence supporting an etiopathogenic role of chronic environmental stress and glucocorticoids (GCs, stress hormones) in the development of the disease. Indeed, both AD and chronic stress are...
BACKGROUND It is essential to determine the specificity of AV-1451 PET for tau in brain imaging by using pathological comparisons. We performed autoradiography in autopsy-confirmed Alzheimer disease and other neurodegenerative disorders to evaluate the specificity of AV-1451 binding for tau aggregates. METHODS Tissue samples were selected that had a variety of dementia-related neuropathologie...
Amyloid precursor protein (APP) is cleaved by gamma-secretase to simultaneously generate amyloid beta (Aβ) and APP Intracellular Domain (AICD) peptides. Aβ plays a pivotal role in Alzheimer's disease (AD) pathogenesis but recent studies suggest that amyloid-independent mechanisms also contribute to the disease. We previously showed that AICD transgenic mice (AICD-Tg) exhibit AD-like features su...
let $r$ be a $*$-prime ring with center $z(r)$, $d$ a non-zero $(sigma,tau)$-derivation of $r$ with associated automorphisms $sigma$ and $tau$ of $r$, such that $sigma$, $tau$ and $d$ commute with $'*'$. suppose that $u$ is an ideal of $r$ such that $u^*=u$, and $c_{sigma,tau}={cin r~|~csigma(x)=tau(x)c~mbox{for~all}~xin r}.$ in the present paper, it is shown that...
objective(s):alzheimer's disease (ad) is the most common age-related neurodegenerative disorder. one of the hallmarks of ad is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. in this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in ad and tauopathies. unfortunately, the available syn...
objective(s):breast cancer is an important leading cause of death from cancer. stathmin and tau proteins are regulators of cell motility, and their overexpression is associated with the progression and bad prognosis of breast cancer. memantine, an n-methyl-d-aspartate (nmda) receptor antagonist, is the potential inhibitor of tau protein in neurons. this study determines the effect of memantine ...
tau is one of several types of microtubule-associated proteins (maps), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses, abe...
Tau is a multiply phosphorylated protein that is essential for the development and maintenance of the nervous system. Errors in Tau action are associated with Alzheimer disease and related dementias. A huge literature has led to the widely held notion that aberrant Tau hyperphosphorylation is central to these disorders. Unfortunately, our mechanistic understanding of the functional effects of c...
