The book "Functional activity of phagocytic cells in healthy individuals and patients with chronic obstructive diseases" edited by Maximova A. In. represents an important contribution to the field of medical sciences, especially to the study of the immune system and its role in the pathogenesis of chronic respiratory diseases. This publication will be of particular interest to specialists in the field of medicine, biology and pharmacology, as well as medical students and anyone who seeks to deepen their knowledge of the functioning of the immune system. The book examines the key role of phagocytic cells, such as macrophages and neutrophils, in protecting the body from infections and inflammatory processes. The authors analyze in detail how chronic obstructive pulmonary disease (COPD) affects the functional activity of these cells, which can lead to a deterioration in the condition of patients and an increased risk of complications. The reader will be able to learn about modern research methods that allow assessing the immune response in healthy and sick people, as well as the importance of this data for the development of new approaches to the treatment and prevention of diseases. The book will be of interest not only to specialists, but also to a wide audience interested in health and medicine. It can be useful to doctors working in the field of pulmonology, therapists, as well as researchers engaged in the study of immunology and pathology of the respiratory system. Students of medical faculties will find in it valuable information that will help them in their studies and future practice. The topics raised in the book cover a wide range of issues, including the mechanisms of inflammation, the interaction of immune system cells and their adaptation to chronic diseases. The authors emphasize the importance of understanding these processes to develop new therapeutic strategies, making the book relevant in light of current health challenges. COPD is one of the most common causes of death in the world, and understanding its pathogenesis can significantly affect the quality of life of millions of people. The style in which the book is written is distinguished by scientific rigor and accessibility. The authors use clear and understandable language, which allows even readers who do not have deep knowledge in the field of medicine to internalize the main ideas and conclusions. The book is replete with illustrations and tables that help to visualize the material presented and make it more visual. Maximova A. In. She is known for her work in immunology and pulmonology, and this publication is no exception. Her previous research has also addressed questions related to phagocytosis and the immune response, which adds value to this book. It is the result of joint work of a team of authors, which allows us to present different points of view and approaches to the problem under study. If you are looking for information about how the immune system copes with chronic diseases, or want to deepen your knowledge about phagocytes and their role in the body, this publication will be an indispensable source for you. The book “Functional activity of phagocytic cells in healthy individuals and patients with chronic obstructive diseases” is not just a scientific work, it is an important step towards understanding the complex mechanisms that are behind our health.
