Cytokines at the Crossroads of Health and Disease

Cytokines have emerged as pivotal regulators of communication between immune and non-immune cells, orchestrating the delicate balance between host defense, inflammation, and tissue homeostasis. Their pleiotropic effects extend far beyond immunology, influencing hematopoiesis, neuroendocrine regulation, tissue repair, and even developmental biology. This book provides a comprehensive exploration of cytokines, the small but powerful proteins that orchestrate immune regulation, inflammation, and intercellular communication. It examines the biology, classification, and mechanisms of cytokines, including interleukins, interferons, tumor necrosis factors, chemokines, and growth factors. Special emphasis is placed on their roles in health and disease, such as infection, autoimmune disorders, allergy, cancer, and tissue repair. By integrating molecular insights with clinical applications, the book bridges fundamental immunology with translational medicine. It also highlights therapeutic advances, including recombinant cytokines, monoclonal antibodies, fusion proteins, and cytokine inhibitors, underscoring their promise and limitations in clinical practice.
