Abstract Ionizing radiation-induced intestinal injury (IRIII), a catastrophic disease that occurs after tumor radiotherapy or accidental nuclear radiation, is lack of sufficient medical countermeasures currently. The gut microbial composition affects the radiosensitivity, and regulation microbiota through dietary adjustments potential solution for mitigating IRIII. Time-restricted feeding (TRF) an emerging behavioral nutrition intervention with pleiotropic health benefits. Whether this pattern influences pathogenesis IRIII remains vague. We evaluated impact TRF on radiosensitivity in study discovered only daytime (DTRF), not nighttime TRF, could ameliorate damage mice received high dose IR. Faecal metagenomic metabolomic studies revealed creatine level was increased by approximate 9 times DTRF, to which Bifidobacterium pseudolongum enrichment contribute. Further investigations showed enable activate energy sensor AMP-activated protein kinase irradiated enterocytes induce phosphorylation downstream effector acetyl-CoA carboxylase, resulting reduced production unsaturated fatty acidsand ferroptosis administration mitigated bacteraemia proinflammatory responses. Blockade import compromised inhibition mitigation DTRF Our demonstrates radioprotective mode functioning reshaping suppress IR-induced ferroptosis, thereby providing effective prevention.

Metabolic-associated fatty liver disease (MAFLD) includes several metabolic dysfunctions caused by dysregulation in the brain–gut–liver axis and, consequently, increases cardiovascular risks and dysfunction. In MAFLD, type 2 diabetes mellitus, obesity, syndrome are frequently present; these conditions related to lipogenesis systemic inflammation. This study aimed review connection between MAFLD. The inflammatory process, cellular alterations hepatocytes stellate cells, hypercaloric diet, sedentarism aggravate prognosis of patients with Thus, understand modulation physiopathology it is necessary include organokines involved this process (adipokines, myokines, osteokines, hepatokines) their clinical relevance project future perspectives condition bring light new possibilities therapeutic approaches. Adipokines responsible for activation distinct signaling different tissues, such as insulin pro-inflammatory cytokines, which important balancing substances avoid MAFLD its progression. Myokines improve quantity quality adipose contributing avoiding development Finally, hepatokines decisive improving or not progression through regulation anti-inflammatory organokines.

Neuroimmune and neurodegenerative ailments impose a substantial societal burden. disorders involve the intricate regulatory interactions between immune system central nervous system. Prominent examples of neuroimmune encompass multiple sclerosis neuromyelitis optica. Neurodegenerative diseases result from neuronal degeneration or demyelination in brain spinal cord, such as Alzheimer's disease, Parkinson's Huntington's amyotrophic lateral sclerosis. The precise underlying pathogenesis these conditions remains incompletely understood. Ferroptosis, programmed form cell death characterised by lipid peroxidation iron overload, plays pivotal role diseases. In this review, we provide detailed overview ferroptosis, its mechanisms, pathways, regulation during progression Furthermore, summarise impact ferroptosis on neuroimmune-related cells (T cells, B neutrophils, macrophages) neural (glial neurons).

Abstract The gut microbiota plays a critical role in maintaining human health, influencing wide range of physiological processes, including immune regulation, metabolism, and neurological function. Recent studies have shown that imbalances composition can contribute to the onset progression various diseases, such as metabolic disorders (e.g., obesity diabetes) neurodegenerative conditions Alzheimer's Parkinson's). These are often accompanied by chronic inflammation dysregulated responses, which closely linked specific forms cell death, pyroptosis ferroptosis. Pathogenic bacteria trigger these death pathways through toxin release, while probiotics been found mitigate effects modulating responses. Despite insights, precise mechanisms influences diseases remain insufficiently understood. This review consolidates recent findings on impact immune‐mediated inflammation‐associated conditions. It also identifies gaps current research explores potential advanced technologies, organ‐on‐chip models microbiome–gut–organ axis, for deepening our understanding. Emerging tools, single‐bacterium omics spatial metabolomics, discussed their promise elucidating microbiota's disease development.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent chronic condition marked by excessive lipid accumulation in hepatic tissue. This disorder can lead to range of pathological outcomes, including metabolic steatohepatitis (MASH) and cirrhosis. Despite extensive research, the molecular mechanisms driving MASLD initiation progression remain incompletely understood. Oxidative stress peroxidation are pivotal "multiple parallel hit model", contributing cell death tissue damage. Gut microbiota plays substantial role modulating oxidative through multiple pathways: impairing intestinal barrier, which results bacterial translocation inflammation; modifying bile acid structure, impacts signaling cascades involved lipidic metabolism; influencing hepatocytes' ferroptosis, form programmed death; regulating trimethylamine N-oxide (TMAO) activating platelet function, both recently identified as pathogenetic factors MASH progression. Moreover, various exogenous impact gut its involvement MASLD-related stress, such air pollution, physical activity, cigarette smoke, alcohol, dietary patterns. manuscript aims provide state-of-the-art overview focused on intricate interplay between microbiota, peroxidation, pathogenesis, offering insights into potential strategies prevent associated complications.
