Molecular Mechanisms of Chronic Stress in Immune Dysregulation: From Cytokine Networks to Clinical Manifestations

This article examines the intricate molecular mechanisms linking chronic stress to immune system dysregulation, with particular emphasis on cytokine networks and their role in disease development. Recent advances in molecular immunology have revealed sophisticated pathways through which persistent stress influences immune function, leading to various pathological conditions. We analyze the complex interactions between neuroendocrine responses and immune regulation, focusing on how stress-induced alterations in cytokine networks affect both innate and adaptive immunity. The article integrates findings from research in extracellular vesicle signaling, metabolic reprogramming, and epigenetic modifications in immune cells under chronic stress conditions. Special attention is given to the tissue-specific immune responses and the role of the gut-brain axis in mediating stress-induced immune alterations. We discuss how these molecular mechanisms contribute to the development of immunodeficiency, autoimmune conditions, and chronic inflammatory states. The review also explores emerging therapeutic strategies based on these molecular insights, including chronoimmunotherapy and targeted cytokine modulation. Understanding these complex interactions provides crucial insights for developing more effective treatments for stress-related immune disorders.
