Abstract Primary sensory neurons in dorsal root ganglia (DRG) have long axons and a high demand for mitochondria, and mitochondrial dysfunction has been implicated in peripheral neuropathy after diabetes and chemotherapy1,2. However, the mechanisms by which primary sensory neurons maintain their...

Post-COVID impairment of memory T cell responses to community-acquired pathogens can be rectified by activating cellular metabolism Infection rates involving bacterial and viral pathogens have increased precipitously after the COVID-19 pandemic. While it has been speculated that higher...

Omics-based computational approaches for biomarker identification, prediction, and treatment of Long COVID Long COVID, or post-acute sequelae of COVID-19 (PASC), is a major global health problem, with cumulative estimates suggesting that around 400 million people worldwide have been affected...

Excessive vigorous exercise impairs cognitive function through a muscle-derived mitochondrial pretender Excessive exercise impairs cognitive function, but the underlying mechanism remains unclear. Here, we show that excessive vigorous exercise-induced lactate accumulation stimulates muscles to...

Extracellular vesicles from long COVID patients promote RUNX2-mediated cellular stress via dysregulated miR-204 and p53 pathway activation [Line breaks added] Background: Subjects with Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC)...

Underlying cause of Gulf War illness confirmed Link to research: Decadelong low basal ganglia NAA/tCr from elevated tCr supports ATP depletion from mitochondrial dysfunction and neuroinflammation in Gulf War illness

Digitally Assessed Long COVID Symptomatology Is Associated With Lymphocyte Mitochondrial Dysfunction and Altered Immune Potential BACKGROUND Postacute sequelae of SARS-CoV-2 infection, also known as long COVID (LC), is a complex and heterogenous condition affecting millions worldwide with a...

Highlights • Plasma profiling of 7,288 proteins during post-exertional malaise in ME/CFS. • ME/CFS participants show sustained immune, metabolic, and neuromuscular dysregulation during post-exercise recovery. • Exertion disrupts T and B cell signaling, IL-17 pathways, and mitochondrial...

Abstract Myalgic Encephalomyelitis (ME), also known as chronic fatigue syndrome (CFS), is a debilitating and heterogeneous disorder marked by persistent fatigue, post-exertional malaise, cognitive impairment, and multisystem dysfunction. Despite its prevalence and impact, the molecular...

Time-restricted eating improves quality of life, heart rate, and mitochondrial function in patients with postural orthostatic tachycardia syndrome. An open-label pilot study Postural orthostatic tachycardia syndrome (POTS) is characterized by an abnormal increase in heart rate upon standing...

Metabolism and Innate Immunity Meet at the Mitochondria Bahat, A., MacVicar, T., & Langer, T Abstract Mitochondria are master regulators of metabolism and have emerged as key signalling organelles of the innate immune system. Each mitochondrion harbours potent agonists of inflammation...

The Role of Mitochondria in Inflammation: From Cancer to Neurodegenerative Disorders Missiroli S, Genovese I, Perrone M, Vezzani B, Vitto VAM, Giorgi C Abstract The main features that are commonly attributed to mitochondria consist of the regulation of cell proliferation, ATP generation, cell...

Muscle Abnormalities in Nonhospitalised Patients With Post–COVID-19 Condition BACKGROUND Post-COVID condition (PCC) affects ~10% of SARS-CoV-2–infected individuals and manifests as persistent symptoms such as fatigue, exercise intolerance and muscle weakness. This study aimed to assess the...

Circulating Levels of SMPDL3B Define Metabolic Endophenotypes and Subclinical Kidney Alterations in Myalgic Encephalomyelitis Myalgic Encephalomyelitis (ME) is a complex, multisystem disorder with poorly understood pathophysiological mechanisms. SMPDL3B, a membrane-associated protein expressed...

The power and potential of mitochondria transfer Borcherding N, Brestoff JR. Preface Mitochondria are believed to have originated through an ancient endosymbiotic process in which proteobacteria were captured and co-opted for energy production and cellular metabolism. Mitochondria segregate...

Now published - see post #7 Preprint https://www.preprints.org/manuscript/202509.2242/v1 Authors: Klaus Wirth, Jürgen M. Steinacker Abstract Severely ill ME/CFS patients are bedridden and suffer from hypersensitivities against light and noise, severe orthostatic intolerance reducing...

Nitric oxide promotes cysteine N-degron proteolysis through control of oxygen availability Kim, Haeun; Tian, Ya-Min; Ratcliffe, Peter J; Keeley, Thomas P Selected proteins containing an N-terminal cysteine (Nt-Cys) are subjected to rapid, O2-dependent proteolysis via the Cys/Arg-branch of the...

Mitochondrial activity tunes nociceptor resilience to excitotoxicity Lin Yuan; Navdeep S Chandel; David Julius The capsaicin receptor, TRPV1, mediates the detection of noxious chemical and thermal stimuli by nociceptors, primary sensory neurons of the pain pathway. Overactivation of TRPV1 leads...
