Mitochondria exhibit tissue-specific physiological functions and are central to the maintenance of cellular homeostasis. Emerging evidence indicates that intercellular mitochondrial transfer is regulated by multiple determinants and exerts a profound influence on the function of both innate and adaptive immune cells. The underlying mechanisms are highly heterogeneous, involving distinct cellular contexts, microenvironmental cues, and modes of intercellular communication. This review summarizes the major triggers and mechanistic pathways governing mitochondrial transfer in immune cells and immune-related diseases, and discusses the therapeutic potential of this process while highlighting key challenges that currently limit its clinical translation. By integrating recent mechanistic insights and translational perspectives, this review aims to provide a conceptual framework for the development of mitochondrial transfer-based strategies in the treatment of immune-mediated disorders.

Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
