Mitochondria serve as the powerhouses of living cells, supplying energy and essential building blocks for cellular activities. The immune system exhibits a dynamic and active characteristic within the body, wherein immune cells are constantly activated and primed for pathogens without causing harmful effects on the self-body. These characteristics necessitate that immune cells function effectively and correctly, supported by a sufficient energy supply and metabolism from the mitochondria. Mitochondrial dysfunction leads to immune dysregulation, resulting in inappropriate inflammation, autoimmunity, immunodeficiency, and hypersensitive responses, all of which contribute to the development of illness and disease. Recent studies on mitochondrial transfer in immune cells indicate that mitochondrial replacement could emerge as a promising tool for rectifying immune cell function. This review will emphasize the role of mitochondria in various immune cell types and explore how mitochondrial dysfunction can result in pathogenesis in different conditions. We also discuss the potential application of mitochondrial transfer and transplantation to- and from immune cells in the context of health and disease.
