Mitochondrion

Mitochondria are organelles found in all cells that have a nucleus. In the human body, that would be all cells except red blood cells. They generate most of a cell's energy by manufacturing adenosine triphosphate, ATP. Mitochondria have their own independent genome called mitochondrial DNA.

Mitochondria biogenesis can be increased via hormesis (exercise, fasting, cryotherapy, and heat therapy, as well as supplements like resveratrol.

Immunity
Mitochondria play crucial role in innate immunity, namely through their induction of interferon production and apoptosis through mitochondrial antiviral signaling protein (MAVS). Many viruses evade host immunity by cleaving or downregulating MAVS.

In human disease
Infection with pathogens, including viruses, bacteria, and parasites, can all induce changes in mitochondrial function and energy metabolism.

Viruses can induce or inhibit mitochondrial processes in order to replicate. "Viruses like Herpes simplex virus 1 deplete the host mitochondrial DNA and some, like human immunodeficiency virus and Hepatitis C Virus, hijack the host mitochondrial proteins to function fully inside the host cell." Hepatitis C has also been shown to "fragment host mitochondria".

Parasites such as Toxoplasma gondii have also been shown to modulate host energy metabolism and dysregulate mitochondrial function,, as have bacteria such as E. coli, which has been shown to modulate mitochondrial receptor function.

Mitochondrial disease has a high prevalence of fatigue and debilitation.

Chronic fatigue syndrome
There is evidence of mitochondrial dysfunction in Chronic Fatigue Syndrome patients. Muscle biopsies have shown evidence of mitochondrial degeneration, deletions of mitochondrial DNA , the reduction of mitochondrial activity , and Sarah Myhill found measurable mitochondrial dysfunction correlating with severity of illness. Myhill also produced improvement by targeting those dysfunctions. Mitochondrial DNA variants correlate with symptoms, symptom clusters & symptom severity.

Mitochondrial disorders can be mistaken for Chronic Fatigue Syndrome.

There is evidence of genetic risk factors for mitochondrial dysfunction in related diseases such as complex regional pain syndrome, postural orthostatic tachycardia syndrome (POTS), and dysautonomia.

Potential treatment
Garth Nicolson has proposed that mitochondrial lipid replacement therapy can ameliorate mitochondrial related fatigue using a proprietary blend of phospholipids called NT Factor.

Courtney Craig has proposed treatment of mitochondrial damage in ME/CFS patients using fasting, caloric restriction and a ketogenic diet.
