Available in PDF, EPUB and Kindle. Book excerpt: Alzheimer’s disease (AD) is the most well-known neurodegenerative disorder, causing dementia. In recent decades, several studies have reported calcium dysregulation in AD occurring through the intervention of several calcium receptors and channels, and affecting different cellular compartments, such as mitochondria, the endoplasmic reticulum, lysosomes, and microdomains within the plasma membrane. Calcium signalling dysregulation is now considered a common proximal cause of dysfunctional neurons and glial supporting cells. This book gathers the newest results and advances in calcium signaling deregulation mechanisms in AD, how they are linked to other players involved in AD, and the potential therapies targeting calcium alterations to treat AD.

Available in PDF, EPUB and Kindle. Book excerpt: Substantial evidence indicates that aberrant neuronal Ca2+ regulation may contribute to the pathogenesis of Alzheimer's disease (AD). The aim of this thesis was to further investigate cellular events associated with elevated neuronal Ca2+ in AD. Proteins altered by increased Ca2+ concentration were assessed in post-mortem neurodegenerative disease brain. Increased amounts of active calpain-1 and decreased amounts of active calpastatin, an endogenous calpain inhibitor, were found in AD brain in comparison to control tissue. In addition, elevated calpain-mediated cleavage of several proteins was found in AD brain, including that of the sodium calcium exchanger (NCX3), which normally acts to extrude excess cellular Ca2+. Mechanisms that contribute to increases in neuronal Ca2+ concentration in AD were identified using a primary culture model of AD. Application of oligomeric A[beta] 1-42 to cells was shown to increase the activity of calpains, caspase-3 and induce tau phosphorylation and cleavage through a pathway dependent upon poly-ADP ribose mediated gating of transient receptor potential cation channel, melatonin subfamily 2 (TRPM2) channels. Finally, to begin to examine the potential role of selected neuronal Ca2+ sensors (NCS) in AD, their expression and distribution was examined in primary neurons under different conditions, and in postmortem AD brain. Decreases in the amounts of two of these proteins, DREAM and hippocalcin, were apparent following A[beta] treatment of primary cortical cultures, and A[beta]-induced a Ca2+-dependent relocalisation of hippocalcin within cells, a phenomenon believed to alter the function of this protein. Therefore, these results may suggest that alterations in NCS proteins influence the response of neurons to A[beta]-induced increases in cellular Ca2+ concentration.

Download or read book Calcium Signaling in Biology and Medicine written by Mylo Sanders and published by American Medical Publishers. This book was released on 2023-09-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process that increases low cytoplasmic concentrations in order to activate specific, essential events required by the cell is defined as calcium signaling. It uses calcium ions (Ca2+) to communicate and carry out intracellular processes often as a step in signal transduction. Calcium signaling plays a crucial role in the regulation of a diverse set of essential functions within the human body. The management of various neurodegenerative disorders such as Alzheimer's disease (AD), Huntington's disease (HD), and Parkinson's disease (PD) requires calcium signaling. It has been observed that disruption in calcium signaling may lead to synaptic deficits which further leads to accumulation of Aβ plaques and neurofibrillary tangles. Calcium plays an important role in various biological processes and calcium signaling has been linked to various diseases. Therefore, it is currently being explored as a therapeutic target for various types of cancer. This book elucidates the concepts and innovative models around prospective developments with respect to the importance of calcium signaling in biology and medicine. It will serve as a valuable source of reference for those interested in this field of study.

Download or read book Calcium Signalling in Cancer written by G. V. Sherbet and published by CRC Press. This book was released on 2000-11-29 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcium signalling occupies a preeminent position in the signal transduction system of the cell by virtue of its participation in a wide range of physiological functions together with the biological events associated with genetic expression, cell proliferation and apoptosis, as well as cell differentiation and morphogenesis. It is an important feature of cell adhesion and motility; the integrity of the calcium binding proteins themselves is a basic requirement of normal biological function. In fact, the deregulation of calcium signaling is now regarded as the primary event in the pathogenesis, growth, invasion, and secondary spread of cancer. Calcium Signalling in Cancer is a concise up-to-date treatise on the transduction signals induced by calcium that considers how alterations in this calcium-dependent signal transduction pathway are related to a number of human diseases, especially neoplastic transformation. This authoritative text examines a broad range of topics-from mechanisms and significance of calcium homeostasis for normal cell function to calcium signalling pathways and the transduction of the calcium signal, especially in proliferation, cell motility, cancer invasion,, and metastasis. Clearly organized, it covers all aspects of the subject including specific sections on the regulation of the genes whose products are required for signal transduction by calcium, such as Alzheimer's disease, Darier's disease, Duchenne and limb girdle dystrophies, psoriasis and some forms of ichthyosis, and cancer associated retinopathy. With an extensive bibliography and over 2,500 references, Calcium Signalling in Cancer is an invaluable reference source.

Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.
