Download or read book Crosstalk between Cell Death Oxidative Stress and Immune Regulation written by Chao Yang and published by Frontiers Media SA. This book was released on 2024-11-11 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell death, a biological event important for maintaining the growth, development, and life processes of organisms, mainly includes programmed death (apoptosis, pyroptosis, autophagy, mitochondrial apoptosis, ferroptosis, cuproptosis, and disulfidptosis, etc.) and non-programmed death (cell necrosis). Many diseases, including cancers, exhibit dysregulated immune activities as key features due to the increase in oxidative stress, which eventually leads to cell death. Understanding the intricate relationships between cell death, oxidative stress, and immune regulation could be critical in elucidating the key molecular mechanisms of these diseases, possibly uncovering novel therapeutics/diagnostics for disease management. For example, ferroptosis, a form of iron-dependent cell death that is triggered by the toxic accumulation of oxidative stress, can induce immunosuppression in tumor neutrophils, whereas inhibition of ferroptosis can slow tumor progression. For another example, pyroptosis, a form of lytic cell death which can be triggered by oxidative stress, when occurs in tumor cells, can induce a strong inflammatory response and significant tumor regression.

Download or read book The Heterogeneity of Cancer Metabolism written by Anne Le and published by Springer. This book was released on 2018-06-26 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic alterations in cancer, in addition to being the fundamental drivers of tumorigenesis, can give rise to a variety of metabolic adaptations that allow cancer cells to survive and proliferate in diverse tumor microenvironments. This metabolic flexibility is different from normal cellular metabolic processes and leads to heterogeneity in cancer metabolism within the same cancer type or even within the same tumor. In this book, we delve into the complexity and diversity of cancer metabolism, and highlight how understanding the heterogeneity of cancer metabolism is fundamental to the development of effective metabolism-based therapeutic strategies. Deciphering how cancer cells utilize various nutrient resources will enable clinicians and researchers to pair specific chemotherapeutic agents with patients who are most likely to respond with positive outcomes, allowing for more cost-effective and personalized cancer therapeutic strategies.
Download or read book Necrotic Cell Death written by Han-Ming Shen and published by Springer Science & Business Media. This book was released on 2014-03-29 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starting with discussion of basic concepts and the molecular mechanisms of necrosis, this book looks first at several forms of necrotic cell death that have been identified, including necroptosis, autophagic cell death, and PARP-mediated cell death. As necrotic cell death is increasingly known to play a critical role in many physiological processes, the next chapters discuss its effect on metabolism, inflammation, immunity, and development. Necrotic cell death is closely implicated in human diseases like cancer, so the next chapters examine its relevance to human diseases, and final chapters cover methodologies for measuring necrosis. This book presents comprehensive coverage of necrosis from recognized experts from leading academic and medical institutions around the world. In contrast to apoptosis, well-defined as a form of programmed cell death, necrosis used to be considered as accidental (i.e., non-programmed) cell death, usually in response to a severe injury. Accumulating evidence now suggests, however, that necrosis is also programmed and controlled by distinctive "death machinery" in response to various stimuli like oxidative stress or DNA damage.

Download or read book Glutathione System and Oxidative Stress in Health and Disease written by and published by BoD – Books on Demand. This book was released on 2020-08-26 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The imbalance between the production of reactive oxygen species (ROS) and antioxidant defenses determines a state known as oxidative stress. Higher levels of pro-oxidants compared to antioxidant defenses may generate oxidative damage, which, in turn, may lead to modifications in cellular proteins, lipids, and DNA, reducing functional capacity and increasing the risk of diseases. Nevertheless, the clearance of harmful reactive chemical species is achieved by the antioxidant defense systems. These protection systems are referred to as the first and second lines of defense and comprise the classic antioxidants, enzymatic and nonenzymatic defenses, including glutathione. This book presents and discusses the advancement of research on health and diseases and their underlying mechanisms, exploring mainly aspects related to the glutathione antioxidant system.
Download or read book Oxidative Stress and Redox Regulation written by Ursula Jakob and published by Springer Science & Business Media. This book was released on 2013-03-15 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many physiological conditions such as host defense or aging and pathological conditions such as neurodegenerative diseases, and diabetes are associated with the accumulation of high levels of reactive oxygen species and reactive nitrogen species. This generates a condition called oxidative stress. Low levels of reactive oxygen species, however, which are continuously produced during aerobic metabolism, function as important signaling molecules, setting the metabolic pace of cells and regulating processes ranging from gene expression to apoptosis. For this book we would like to recruit the experts in the field of redox chemistry, bioinformatics and proteomics, redox signaling and oxidative stress biology to discuss how organisms achieve the appropriate redox balance, the mechanisms that lead to oxidative stress conditions and the physiological consequences that contribute to aging and disease.

Download or read book Oxidative Stress and Signal Transduction written by H.J. Forman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years there has been the increased recognition that the effects of oxidative stress are not limited to the damage of cellular constituents. There is now evidence that reactive oxygen species (ROS) can alter cell function by acting upon the intermediates, or second messengers, in signal transductions. Such effects on signaling mechanisms probably account for the role of oxidative stress in inflammation, aging, and cancer. This volume brings together internationally recognized researchers in both the major areas covered by the book, oxidative stress and signal transduction. The work is organized in three sections. The first deals with the immediate cellular responses to oxidative stress and the production of second messengers. The second details the connection between second messengers and the gene. The third part looks more closely at the level of the gene.
Download or read book Neuroprotection written by Bae Hwan Lee and published by Mdpi AG. This book was released on 2021-09-27 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dear Colleagues, The brain is vulnerable to injury. Following injury in the brain, apoptosis or necrosis may occur easily, leading to various functional disabilities. Neuronal death is associated with a number of neurological disorders including hypoxic ischemia, epileptic seizures, and neurodegenerative diseases. The brain subjected to injury is regarded to be responsible for the alterations in neurotransmission processes, resulting in functional changes. Oxidative stress produced by reactive oxygen species has been shown to be related to the death of neurons in traumatic injury, stroke, and neurodegenerative diseases. Therefore, scavenging or decreasing free radicals may be crucial for preventing neural tissues from harmful adversities in the brain. Neurotrophic factors, bioactive compounds, dietary nutrients, or cell engineering may ameliorate the pathological processes related to neuronal death or neurodegeneration and appear beneficial for improving neuroprotection. As a result of neuronal death or neuroprotection, the brain undergoes activity-dependent long-lasting changes in synaptic transmission, which is also known as functional plasticity. Neuroprotection implying the rescue from neuronal death is now becoming one of global health concerns. This Special Issue attempts to explore the recent advances in neuroprotection related to the brain. This Special Issue welcomes original research or review papers demonstrating the mechanisms of neuroprotection against brain injury using in vivo or in vitro models of animals as well as in clinical settings. The issues in a paper should be supported by sufficient data or evidence. Prof. Bae Hwan Lee Guest Editor

Download or read book Crosstalk between Peripheral and Local Immune Response in the Pathophysiology of Stroke and Neurodegeneration Diseases Volume II written by Yuanjian Fang and published by Frontiers Media SA. This book was released on 2024-03-06 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accumulating evidence reveals both local and peripheral immune systems participated in the pathophysiology changes of acute and chronic neurological diseases. Immune cell activation facilitates inflammatory response in neurological diseases such as stroke, Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis. The immune response initiated by brain local cells (microglia and astrocytes) and peripheral blood cells (monocytes/macrophages, neutrophil, T cells, B cells), are now commonly thought to contribute “double-edged sword” effects to the progression of neurological diseases, which not only promoting repair and recovery, but also accelerating brain injury. Meanwhile, local and peripheral immune responses have complex crosstalk in the development of post-stroke injury and neurodegeneration disease.

Download or read book Reviews on New Drug Targets in Age Related Disorders written by Paul C. Guest and published by Springer. This book was released on 2020-06-07 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging is an inevitable part of life and is becoming a worldwide social, economic and health problem. This is mainly due to the fact that the increasing proportion of individuals in the advanced age category have a higher probability of developing age-related disorders, such as type II diabetes mellitus, cardiovascular disorders, sarcopenia, and neurodegenerative conditions. New therapeutic approaches are still needed to decrease or slow the effects of such diseases. Advances in -omic technologies, such as genomics, transcriptomics, proteomics and metabolomics, have significantly advanced our understanding of disease in multiple medical areas, as the analysis of multiple molecular networks has simultaneously provided a more integrated view of disease pathways. It is hoped that emerging hits from these analyses might be prioritized for further screening as potential novel drug targets for increasing the human healthspan in line with the lifespan. In turn, this will lead to new therapeutic strategies as well as drug development projects by the pharmaceutical industry. This book presents a series of reviews describing studies that have resulted in identification of new potential drug targets for age-related disorders. Much of this information has come from -omic comparisons of healthy and disease states or from testing the effects of new therapeutic approaches. Authored by experts from around the globe, each chapter is presented in the context of specific chronic diseases or therapeutic strategies. This book is designed for researchers in the areas of aging and chronic disease, as well as clinical scientists, physicians and stakeholders in major drug companies.
