Involvement of neutrophils and macrophages in exhaustive exercise-induced liver, kidney, heart, and lung injuries.
Moderate exercise is effective for maintaining or improving overall health. However, excessive exercise that exhausts the adaptive reserve of the body or its ability to positively respond to training stimuli can induce tissue damage and dysfunction of multiple organs and systems. Tissue injury, inflammation, and oxidative stress are reportedly induced in the skeletal muscles, liver, and kidneys after exercise. However, the precise mechanisms underlying acute tissue injury after intense exercise have not yet been fully elucidated. Studies using various experimental models of acute tissue injury, other than intense exercise, have demonstrated infiltration of inflammatory cells, including neutrophils and macrophages. These cells infiltrate injured tissues and induce inflammatory and oxidative stress responses by producing inflammatory cytokines and reactive oxygen species, thereby exacerbating tissue injury. In addition to the activation of blood neutrophils and increase in their levels during and/or after prolonged or intense exercise, chemokines that contribute to leukocyte migration are released, facilitating the migration of neutrophils and monocytes into tissues. Therefore, neutrophils and macrophages, activated by exhaustive exercise, may infiltrate tissues and contribute to exhaustive exercise-induced tissue injury. Recently, the contributions of neutrophils and macrophages to various tissue injuries caused by exhaustive exercise have been reported. In this review, we summarize the involvement of neutrophils and monocytes/macrophages in exhaustive exercise-induced non-skeletal muscle tissue injury. In addition, we present novel data demonstrating the contribution of neutrophils and macrophages to exhaustive exercise-induced cardiac and pulmonary injuries. Our study findings and the evidence presented in this review suggest that neutrophils and macrophages may play pivotal roles in exhaustive exercise-induced tissue injuries.
期刊介绍:
Exercise Immunology Review (EIR) serves as the official publication of the International Society of Exercise and Immunology and the German Society of Sports Medicine and Prevention. It is dedicated to advancing knowledge in all areas of immunology relevant to acute exercise and regular physical activity. EIR publishes review articles and papers containing new, original data along with extensive review-like discussions. Recognizing the diverse disciplines contributing to the understanding of immune function, the journal adopts an interdisciplinary approach, facilitating the dissemination of research findings from fields such as exercise sciences, medicine, immunology, physiology, behavioral science, endocrinology, pharmacology, and psychology.
