Key Takeaway
Interpret mitochondrial transfer mechanisms as emerging concepts without clinical outcome data.

This systematic review synthesizes current evidence on the mechanisms and potential roles of intercellular mitochondrial transfer in remodeling immune microenvironments. The review covers diverse physiological and pathological contexts including inflammation, cancer, and autoimmune diseases, though specific study populations, sample sizes, and clinical settings are not reported. No specific interventions, comparators, or primary outcomes are detailed, as this is a review of concepts rather than a report of original clinical trial data.

The main conceptual finding is that mitochondrial transfer occurs through mechanisms including tunneling nanotubes, extracellular vesicles, and gap junctions. This transfer may reshape immune niches by influencing metabolic fitness, redox balance, inflammatory tone, and immune cell interactions. No quantitative results, effect sizes, statistical measures, or direction of effects are reported, as the review focuses on summarizing mechanisms from emerging evidence.

Safety and tolerability data are not reported. The review acknowledges its limitations as a conceptual summary that does not present primary clinical data, patient outcomes, or quantitative effect measures. No causal claims from primary human studies are presented. The practice relevance is not specified, and clinicians should interpret this as a mechanistic overview of an emerging research area rather than evidence supporting specific clinical applications.

Scientists reviewed existing research on a process called mitochondrial transfer. This is when one cell donates its energy-producing mitochondria to another cell. The review explored how this transfer might change the local immune environment in diseases like cancer, inflammation, and autoimmune disorders.

The authors summarized evidence suggesting this transfer can happen through tiny tunnels or vesicles between cells. They propose this could affect a cell's energy levels, stress responses, and inflammatory signals, potentially altering how the immune system behaves in diseased tissues.

It is important to understand this is a review article. It did not conduct new experiments or study patients. It compiled ideas and early evidence from other lab and animal studies. The findings are theoretical mechanisms, not results from human clinical trials.

Readers should see this as scientists explaining a complex biological concept that is still being researched. It highlights an area of active investigation but does not mean this process is ready to be used for diagnosis or treatment in people. Much more research is needed to understand if and how targeting mitochondrial transfer could help patients.

What this means for you:
A review describes how cells might share mitochondria to affect immunity, but this is early-stage biological research, not a new therapy.

Mitochondria are central regulators of immunometabolism, and emerging evidence identifies intercellular mitochondrial transfer as a key driver of immune microenvironment remodeling. Beyond energy production, transferred mitochondria reshape immune niches by reprogramming metabolic fitness, redox balance, inflammatory tone, and immune cell interactions. Through multiple transfer routes, including tunneling nanotubes, extracellular vesicles, and gap junctions, mitochondrial exchange modulates immune activation, immunosuppression, and tolerance across diverse physiological and pathological contexts. In this review, we summarize current mechanisms of mitochondrial transfer and highlight how this process directionally remodels the immune microenvironment in inflammation, cancer, and autoimmune diseases. We further discuss therapeutic strategies aimed at modulating mitochondrial transfer to reprogram immune responses, providing new perspectives for immunomodulation and disease intervention.
