Download or read book Deciphering the T Cell Response in SARS CoV 2 Infection written by Alessio Mazzoni and published by Frontiers Media SA. This book was released on 2024-07-22 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: COVID-19 is a recently emerged infectious disease caused by the novel coronavirus SARS-CoV-2. The immune system has a primary role in pathogen elimination and a rapid and effective response can limit disease severity. In this context, T cells play the major role in cell mediated adaptive immune response. The protective role of CD4+ and CD8+ T cells has been inferred from studies on patients who recovered from SARS and MERS and accumulating data are now showing their relevance in SARS-CoV-2 infection. Moreover, memory T cells induced by previous pathogens can shape the susceptibility to, and the clinical severity of other infections, but the complete picture has yet to be elucidated. If the virus is not rapidly eliminated, COVID-19 may progress towards a secondary inflammatory phase that is directly responsible for a worsening in clinical symptoms and immune system impairment. Besides marked lymphopenia, COVID-19 patients’ T cell compartment displays several alterations involving different subpopulations of T cells in terms of phenotype, metabolic profile and functionality.
Download or read book The Coronaviridae written by Stuart G. Siddell and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronaviruses were recognized as a group of enveloped, RNA viruses in 1968 and accepted by the International Committee on the Taxonomy of Viruses as a separate family, the Coronaviridae, in 1975. By 1978, it had become evident that the coronavirus genomic RNA was infectious (i. e. , positive strand), and by 1983, at least the framework of the coronavirus replication strategy had been per ceived. Subsequently, with the application of recombinant DNA techniques, there have been remarkable advances in our understanding of the molecular biology of coronaviruses, and a mass of structural data concerning coronavirus genomes, mRNAs, and pro teins now exists. More recently, attention has been focused on the role of essential and accessory gene products in the coronavirus replication cyde and a molecular analysis of the structure-function relation ships of coronavirus proteins. Nevertheless, there are still large gaps in our knowledge, for instance, in areas such as the genesis of coronavirus subgenomic mRNAs or the function of the coronavirus RNA-dependent RNA polymerase. The diseases caused by coronaviruses have been known for much longer than the agents themselves. Possibly the first coronavirus-related disease to be recorded was feline infectious peritonitis, as early as 1912. The diseases associ ated with infectious bronchitis virus, transmissible gastroenteritis virus, and murine hepatitis virus were all well known before 1950.

Download or read book Understanding Coronavirus written by Raul Rabadan and published by Cambridge University Press. This book was released on 2021-10-14 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the identification of the first cases of the coronavirus in December 2019, there has been a significant amount of confusion regarding the origin and spread of the so-called 'coronavirus', SARS-CoV-2, and the cause of the disease COVID-19. Conflicting messages from the media and officials across different countries and organizations, the abundance of disparate sources of information, unfounded conspiracy theories on the origins of the virus, unproven therapies, and inconsistent public health measures, have all served to increase anxiety in the population. Where did the virus come from? How is it transmitted? How does it cause disease? Is it like flu? What is a pandemic? In this concise and accessible introduction, a leading expert provides answers to these commonly asked questions. This revised and updated edition now also covers how the virus mutates, how important these mutations are, how vaccines work, and what we can expect in the near and long-term future.
Download or read book Immunology and Aging written by Takashi Makinodan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the classic sense, immunity is the ability of an organism to resist disease. On the one hand, we must distinguish between age and disease; on the other hand, the interaction between them is of considerable theoretical and practical interest. To the gerontologic research community, therefore, immunity also becomes the ability of an organism to resist age. Were the immune and other protective systems of the body able to maintain themselves over the course of time, and if there were no degradation related to age, the everyday loss of energy and vitality that occurs in the lives of older people as a consequence of viruses, arthritis, and other debilitating circumstances would be greatly lessened. The objective of gerontologists is not just to extend the life span but rather to improve the vigor, health, and quality oflife. To date, we have not developed a single index to measure immunity that is of use clinically in the evaluation of older people and of their immunologic compe tence. It may not be surprising that just such a clinical index may be available in the not-too-distant future. We can also look forward to the assembling of a greater body of information explaining how and why the immune system fails with age while, paradoxically, the incidence of autoimmune diseases increases with age. It is this latter phenomenon that may playa part in a wide range of chronic diseases from rheumatoid arthritis to senile dementia.
Download or read book Slum Health written by Jason Corburn and published by Univ of California Press. This book was released on 2016-06-07 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban slum dwellers—especially in emerging-economy countries—are often poor, live in squalor, and suffer unnecessarily from disease, disability, premature death, and reduced life expectancy. Yet living in a city can and should be healthy. Slum Health exposes how and why slums can be unhealthy; reveals that not all slums are equal in terms of the hazards and health issues faced by residents; and suggests how slum dwellers, scientists, and social movements can come together to make slum life safer, more just, and healthier. Editors Jason Corburn and Lee Riley argue that valuing both new biologic and “street” science—professional and lay knowledge—is crucial for improving the well-being of the millions of urban poor living in slums.

Download or read book Structural Immunology written by Tengchuan Jin and published by Springer Nature. This book was released on 2019-10-18 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of important immune molecules and their structure-function relationships. The immune system is highly complex, consisting of a network of molecules, cells, tissues and organs, and the immune reaction is involved in various physiological as well as pathological processes, including development, self-tolerance, infection, immunity, and cancer. Numerous molecules participate in immune recognition, inhibition and activation, and these important immune molecules can be roughly divided into cell surface receptors, intracellular receptors and intracellular signaling molecules. The study of how these immune molecules function at molecular level has laid the foundation for understanding the immune system. The book provides researchers and students with the latest research advances concerning the structural biology of key immune molecules/pathways, and offers immunologists essential insights into how these immune molecules function.

Download or read book Immunoregulation written by Nicola Fabris and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunoregulation is one of the areas which has witnessed the most explosive advances of immunology during the past decade. It is in this area that the current view of the immune system has arisen and developed. There is indeed little doubt that immune reactions are primarily determined by messages which are genera ted within the immune system and passed among different types of immunologie cells. This cell communication not only determines the type, intensity and duration of the response after perturbation of the immune system by exogenous antigens, but it is also essential for preventing autoimmune reactions and their clinical conse quences. In order to assure aperfect balance within the enormous com plexity of the immune system, it is not surprising that multiple self-regulatory mechanisms are organized at different levels, such as antibody feedback, idiotypic-anti-idiotypic responses, suppres sor and helper T cells, lymphokine signals and genetic require ments. A nu mb er of observations in recent years have, however, demonstrated that consistent contributions to the immunological homeostasis are given also by signals generated outside of the immune system, namely,in the central and autonomous nervous system as weIl as in the endocrine apparatus. Furthermore, the interactions between the immune system and the other body homestatic mechanisms seem to be bidirectional: if immunological cells may be targets of neuroendocrinological factors, immunological products seem in turn to contribute to the neuro endocrine homeostasis.
Download or read book Molecular Biology of the SARS Coronavirus written by Sunil K. Lal and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: SARS was the ?rst new plague of the twenty-?rst century. Within months, it spread worldwide from its “birthplace” in Guangdong Province, China, affecting over 8,000 people in 25 countries and territories across ?ve continents. SARS exposed the vulnerability of our modern globalised world to the spread of a new emerging infection. SARS (or a similar new emerging disease) could neither have spread so rapidly nor had such a great global impact even 50 years ago, and arguably, it was itself a product of our global inter-connectedness. Increasing af?uence and a demand for wild-game as exotic food led to the development of large trade of live animal and game animal markets where many species of wild and domestic animals were co-housed, providing the ideal opportunities for inter-species tra- mission of viruses and other microbes. Once such a virus jumped species and attacked humans, the increased human mobility allowed the virus the opportunity for rapid spread. An infected patient from Guangdong who stayed for one day at a hotel in Hong Kong led to the transmission of the disease to 16 other guests who travelled on to seed outbreaks of the disease in Toronto, Singapore, and Vietnam, as well as within Hong Kong itself. The virus exploited the practices used in modern intensive care of patients with severe respiratory disease and the weakness in infection control practices within our health care systems to cause outbreaks within hospitals, further amplifying the spread of the disease. Health-care itself has become a two-edged sword.
