    Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults, 2022, Sophia Liu, PhD et al

    Abstract Importance Aging is associated with a decline in mitochondrial function and reduced exercise capacity. Urolithin A is a natural gut microbiome–derived food metabolite that has been shown to stimulate mitophagy and improve muscle function in older animals and to induce mitochondrial...

    Vitamin K2 Modulates Mitochondrial Dysfunction Induced by 6-Hydroxydopamine in SH-SY5Y Cells via Mitochondrial Quality-Control Loop, 2022, Henfang et

    Abstract Vitamin K2, a natural fat-soluble vitamin, is a potent neuroprotective molecule, owing to its antioxidant effect, but its mechanism has not been fully elucidated. Therefore, we stimulated SH-SY5Y cells with 6-hydroxydopamine (6-OHDA) in a proper dose-dependent manner, followed by a...

    Gut-Derived Metabolite Indole-3-Propionic Acid Modulates Mitochondrial Function in Cardiomyocytes and Alters Cardiac Function, 2021, Gesper et al

    Background: The gut microbiome has been linked to the onset of cardiometabolic diseases, in part facilitated through gut microbiota-dependent metabolites such as trimethylamine-N-oxide. However, molecular pathways associated to heart failure mediated by microbial metabolites remain largely...

    Footprints of a microbial toxin from the gut microbiome to mesencephalic mitochondria, 2021, Esteves et al

    In mice. Abstract Objective Idiopathic Parkinson’s disease (PD) is characterised by alpha-synuclein (aSyn) aggregation and death of dopaminergic neurons in the midbrain. Recent evidence posits that PD may initiate in the gut by microbes or their toxins that promote chronic gut inflammation...

    Porphyromonas gingivalis infection promotes mitochondrial dysfunction through Drp1-dependent mitochondrial fission in endothelial cells, 2021,Xu et al

    Abstract Porphyromonas gingivalis (P. gingivalis), a key pathogen in periodontitis, has been shown to accelerate the progression of atherosclerosis (AS). However, the definite mechanisms remain elusive. Emerging evidence supports an association between mitochondrial dysfunction and AS. In our...

    Redox imbalance links COVID-19 and myalgic encephalomyelitis/chronic fatigue syndrome, 2021, Paul, Komaroff et al

    Abstract Although most patients recover from acute COVID-19, some experience postacute sequelae of severe acute respiratory syndrome coronavirus 2 infection (PASC). One subgroup of PASC is a syndrome called “long COVID-19,” reminiscent of myalgic encephalomyelitis/chronic fatigue syndrome...

    Radiation exposure and mitochondrial insufficiency in chronic fatigue and immune dysfunction syndrome, 2021, Rusin et al

    Abstract Chronic fatigue and Immune Dysfunction Syndrome (CFIDS) is a heterogeneous disease that may be promoted by various environmental stressors, including viral infection, toxin uptake, and ionizing radiation exposure. Previous studies have identified mitochondrial dysfunction in CFIDS...

    Individual physiological and mitochondrial responses during 12 weeks of intensified exercise, 2021, Jacques et al

    Abstract Aim Observed effects of exercise are highly variable between individuals, and subject-by-training interaction (i.e., individual response variability) is often not estimated. Here, we measured mitochondrial (citrate synthetase, cytochrome-c oxidase, succinate dehydrogenase, and...

    Reduction of host cell mitochondrial activity as Mycobacterium leprae’s strategy to evade host innate immunity, 2021, Oliveira et al

    Abstract Leprosy is a much‐feared incapacitating infectious disease caused by Mycobacterium leprae or M lepromatosis, annually affecting roughly 200,000 people worldwide. During host‐pathogen interaction, M leprae subverts the immune response, leading to development of disease. Throughout the...

    Pathophysiology of skeletal muscle disturbances in (ME/CFS): 2021, Wirth, Scheibenbogen

    Abstract Chronic Fatigue Syndrome or Myalgic Encephaloymelitis (ME/CFS) is a frequent debilitating disease with an enigmatic etiology. The finding of autoantibodies against ß2-adrenergic receptors (ß2AdR) prompted us to hypothesize that ß2AdR dysfunction is of critical importance in the...
