Download or read book Molecular Mechanisms Involved in Neurotoxicity Mediated by HIV Proteins and Drug Abuse written by Yu Cai and published by . This book was released on 2016 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the advancement of highly active antiretroviral therapy (HAART) has transformed the course of HIV/AIDS from a death sentence to a manageable chronic condition, the prevalence of a constellation of neurological disorders collectively termed as HIV-associated neurocognitive disorders (HAND) continues to persist in these patients. HAND is characterized by cognitive dysfunction, depression, impaired memory and/or deficits in motor skills. The underlying factors leading to HAND have been the subject of extensive research and are thought to be associated with HIV infection in the CNS combined with robust immune activation of resident cells of the CNS. In addition, there is a strong correlation between chronic substance abuse and the manifestation of HAND, posing a major challenge for health care management in HIV-positive drug abusers. One of the hallmark features of cocaine and opiate abuse is the increased neuronal toxicity in the setting of HIV infection. Among the various commonly abused drugs, cocaine has been extensively studied for its ability to exacerbate the neuropathogenesis of HAND. Ample evidence suggests that cocaine not only facilitates viral replication in astrocytes and microglia, enhances the permeability of the blood-brain barrier (BBB) and exacerbates neuroinflammatory responses, working synergistically with viral proteins such as HIV Tat and virus envelop protein Gp120 to promote neuronal injury. Sigma-1 receptors (Sig-1R) are recognized as a unique class of non-G protein-coupled intracellular protein that binds to their ligands such as cocaine, resulting in dissociation of Sig-1R from mitochondrion-associated ER membrane (MAM) to the endoplasmic reticulum (ER), plasma membrane, and nuclear membrane, regulating function of various proteins. Sig-1R has diverse roles in both physiological as well as in pathogenic processes. The disruption of Sig-1R pathways has been implicated as causative mechanism(s) in the development of neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and Huntington Disease (HD). Additionally, the interaction of cocaine and Sig-1R has more recently been implicated in potentiating the pathogenesis of HAND through impairment of BBB, microglial activation and astrogliosis. Opiates such as morphine are commonly used clinically in palliative care and pain management. Chronic exposure to morphine and other opioids however, can result in significant detrimental effects on cognition. Our findings suggest that morphine dysregulates synaptic balance in the hippocampus, a key center for learning and memory, via a novel signaling pathway involving reactive oxygen species (ROS), endoplasmic reticulum stress (ER stress) and autophagy. We demonstrate herein that morphine treatment leads to a reduction in excitatory and a concomitant enhancement of inhibitory synapse densities in the hippocampal neurons via activation of the mu opioid receptor. Furthermore, these effects are mediated by the ability of morphine to upregulate intracellular ROS from nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase), which in turn, promotes ER stress and the induction of autophagy, leading ultimately to decreased excitatory and increased inhibitory synapse densities. The detrimental effects of morphine on synaptic densities were shown to be reversed by platelet-derived growth factor (PDGF), a pleiotropic growth factor, that has been implicated in neuroprotection, at the level of intracellular ROS. Both abnormal unfolded protein response (UPR) and impaired autophagy have also been implicated as a causative mechanism in the development of various neurodegenerative diseases. The common underlying feature of most neurodegenerative diseases such as AD, prion diseases, PD, and ALS involves accumulation of misfolded proteins leading to initiation of endoplasmic ER stress and stimulation of the UPR. Additionally, ER stress has more recently been implicated in the pathogenesis of HAND. Autophagy plays an essential role in the clearance of aggregated toxic proteins and degradation of the damaged organelles. These results thus identify a novel cellular mechanism involved in morphine-mediated synaptic alterations with implications for impaired cognition as well as neurocognitive disorders. Furthermore, based on our findings, it can be speculated that therapeutic strategies aimed at activating PDGF signaling can be envisioned as possible approaches to block morphine-mediated cognitive decline.

Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.
Download or read book How Tobacco Smoke Causes Disease written by and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Download or read book Neuropathology of Drug Abuse written by Andreas Büttner and published by Springer Nature. This book was released on 2020-10-27 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the current state of knowledge concerning neuropathologies resulting from drug abuse. The first chapters offer readers detailed information on the neurobiological basics of drug abuse and the results of neuroimaging studies in drug abusers. The focus of the book is on neuropathological findings in drug abusers for the predominant substances, which include cannabis, opiates, cocaine, amphetamine, methamphetamine and a broad spectrum of designer drugs. These findings are supported by histological illustrations and discussed in connection with recent scientific publications. A chapter specifically addressing clinicians is also included, and highlights the implications for further therapy. The book is essential reading for neuropathologists, neurologists, neuroradiologists and psychiatrists, as well as other health professionals and scientists interested and engaged in the problem of drug abuse. Although a great deal of data has been derived from animal models and from human neuroimaging studies, little is known about the morphological effects of drug abuse on the human brain. In recent years, fundamental drug-induced effects on the cellular elements of the brain have been detected. These alterations might not only be the substrate of the neuroimaging data but might also have implications for clinical research and therapy. In addition, drug abuse may induce premature neurodegeneration.
