Download or read book The Role of Nutrient Sensing in Macrophage Polarization written by Anthony Joseph Covarrubias and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolic diseases, such as obesity and Type-II diabetes, are associated with chronic low-grade inflammation due to dysregulation of metabolic and inflammatory signaling pathways. During obesity monocytes infiltrate adipose tissue and polarize to M1 macrophages, displacing the M2 macrophages normally found in non-obese tissue. These M1 macrophages produce high levels of pro-inflammatory cytokines, which contributes to the development of insulin resistance and type-2 diabetes. Interestingly, while macrophages reside in all metabolic organs such as adipose tissue, how the nutrient status of the host affects macrophages function is not well understood. Thus, my thesis seeks to provide a clearer understanding of this important relationship and is of significant relevance to metabolic health and dysfunction.

Download or read book Macrophages Role in Integrating Tissue Signals and Biological Processes in Chronic Inflammation and Fibrosis written by Tarcio Teodoro Braga and published by Frontiers Media SA. This book was released on 2017-10-13 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages comprehend a heterogeneous mononuclear phagocytic population with wide range phenotypes and roles in homeostasis maintenance and diseases, such as infections, autoimmunity and cancer. Technology improvements enable researchers to track different macrophage populations in different tissues and situations and hypothesize on their role in promoting inflammation or stimulating tissue repair. Through innate immune recognition system macrophages can launch several effector artilleries that culminate in the production of various types of inflammatory mediators as cytokines, chemokines, lipid mediators and oxygen reactive species, which in turn, influence the behavior of other cells. Furthermore, macrophages and interacting cells are also susceptible to metabolic changes that ultimately will define the outcome macrophage signaling and its effect in the tissue. Here, we present a concise series of discussions on the role of macrophages, its response to the microenvironment and effects on other cells during tissue injury and repair. Triggering of inflammasome in macrophage activation and function is of special interest in this issue. We will emphasize the role of different macrophage subpopulations and the plasticity of these cells during fibrotic process in different models of diseases.
Download or read book The M2 Macrophage written by Tamás Röszer and published by Springer Nature. This book was released on 2020-08-03 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages are core components of the innate immune system. Once activated, they may have either pro- or anti-inflammatory effects that include pathogen killing, safe disposal of apoptotic cells or tissue renewal. The activation state of macrophages is conceptualized by the so-called M1/M2 model of polarization. M2 macrophages are not simply antagonists of M1 macrophages; rather, they represent a network of tissue resident macrophages with roles in tissue development and organ homeostasis. M2 macrophages govern functions at the interfaces of immunity, tissue development and turnover, metabolism, and endocrine signaling. Dysfunction in M2 macrophages can ruin the healthy interplay between the immune system and metabolic processes, and lead to diseases such as insulin resistance, metabolic syndrome, and type 1 and 2 diabetes mellitus. Furthermore, M2 macrophages are essential for healthy tissue development and immunological self-tolerance. Worryingly, these functions of M2 macrophages can also be disrupted, resulting in tumor growth and autoimmunity. This book comprehensively discusses the biology of M2 macrophages, summarizes the current state of knowledge, and highlights key questions that remain unanswered.

This book was released on 2020-01-17 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the World Health Organization, the epidemic of global obesity has nearly tripled since 1975. In 2016, more than 1.9 billion adults were overweight, over 650 million of which were obese. Being overweight and obese has been linked to a number of non-communicable, chronic diseases. Pathophysiology of Obesity-Induced Health Complications is a compilation of review articles dedicated to describe co-morbidities associated with obesity. The wide range that is covered is of significant interest to basic research scientists, clinicians and graduate students who are engaged in studying obesity-induced health complications. Furthermore, this book highlights the potential of novel approaches for the prevention and treatment of obesity and its related illnesses. Nineteen articles in this book are organized in four sections that are designed to provide an overview of obesity-induced health complications. The first section serves as an introductory section on the prevalence, causes, consequences, treatments and preventive approaches for obesity. Section two covers the metabolic disturbances and inflammation due to obesity. The third section is focused on neurological and visceral complications as a consequence of obesity. The final section covers strategies for the prevention of obesity-induced complications. The book illustrates that obesity can result in a diverse range of pathophysiological conditions that adversely affect health.

Download or read book Understanding the Crosstalk Between Immune Cells and the Tumor Microenvironment in Cancer and Its Implications for Immunotherapy written by Noha Mousaad Elemam and published by Frontiers Media SA. This book was released on 2023-09-13 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the current challenges and failures of immunotherapy is in part due to the complex tumor microenvironment (TME) that provides a formidable barrier to immune infiltration and function. The TME consists of various cell types (tumor cells, fibroblasts, endothelial cells, and immune cells), soluble signaling molecules (cytokines, growth factors, and chemokines), and extracellular matrix. On another note, metabolic disturbances in various TME components, such as hypoxia, acidosis, lactate accumulation, and nutrient deprivation, can play a critical role in the tumor progression. Furthermore, genetic and epigenetic dysfunctions are known to be part of the characteristics of cancer development. The immune cells could have a pro- or anti-tumor role in the TME, and their activity might vary in the context of different cancers. Both innate and adaptive immune cells interact with tumor cells through direct contact or through chemokines and cytokines signaling, shaping the tumor's activity and response to therapy.

Download or read book Plasticity and Metabolic Switching in Adipose Tissue Macrophages written by Junji Xing and published by Frontiers Media SA. This book was released on 2023-09-05 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrophages are the most common immune cells present in adipose tissues. These adipose tissue macrophages (ATMs) have an important role in regulating homeostasis and contributing to the metabolically harmful chronic inflammation seen in some obese individuals. Macrophages are cells exhibiting plasticity, that is to alter their polarization between pro- and anti-inflammatory phenotypes, in response to stimuli in their microenvironments. There has been a deal of evidence supporting the heterogeneity of these ATM populations, however, research into their differential functionality, developmental origin, and phenotype warrants further research to reach a consensus. Further questions remain regarding the nature of this macrophage differentiation and plasticity, and whether it is innately determined or is induced by the specific adipose tissue microenvironment. Differences in the phenotypes of metabolically unhealthy obese (MUO) and the metabolically healthy obese (MHO) individuals suggest that there are differences in both tissues and overall systemic function. The divergent phenotypes seen in MHO and MUO individuals provides evidence that differences in adipose tissue function are determined by local inflammatory responses driven by macrophage plasticity towards pro-inflammatory phenotypes.

Available in PDF, EPUB and Kindle. Book excerpt: The enormous advances in molecular biology that have been witnessed in . Not recent years have had major impacts on many areas of the biological sciences least of these has been in the field of clinical bacteriology and infectious disease . Molecular Bacteriology: Protocols and ClinicalApplications aims to provide the reader with an insight into the role that molecular methodology has to play in modern medical bacteriology. The introductory chapter ofMolecular Bacteriology: ProtocolsandCli- cal Applications offers a personal overview by a Consultant Medical Microbio- gist of the impact and future potential offered by molecular methods. The next six chapters comprise detailed protocols for a range of such methods . We believe that the use of these protocols should allow the reader to establish the various methods described in his or her own laboratory. In selecting the methods to be included in this section, we have concentrated on those that, arguably, have greatest current relevance to reference clinical bacteriology laboratories; we have deliberately chosen not to give detailed protocols for certain methods, such as multilocus enzyme electrophoresis that, in our opinion, remain the preserve of specialist la- ratories and that are not currently suited for general use. We feel that the methods included in this section will find increasing use in diagnostic laboratories and that it is important that the concepts, advantages, and limitations of each are th- oughly understood by a wide range of workers in the field .
