Bacillus Licheniformis‐Induced Cognitive Decline in Mice Linking Gut Microbiota Dysbiosis, Metabolic Perturbations, and Hippocampal Neuroinflammation

Advanced Science, EarlyView.
Chronic oral administration of specific probiotic strains triggers gut microbiota dysbiosis and systemic metabolic perturbations in mice. Multi‐omics profiling reveals subsequent hippocampal glial remodeling and neuroinflammation, which are linked to cognitive impairment.

Kynurenines and Neurofilament Light Chain in Multiple Sclerosis

Frontiers in Neuroscience, 2021
Multiple sclerosis is an autoimmune, demyelinating, and neurodegenerative disease of the central nervous system. In recent years, it has been proven that the kynurenine system plays a significant role in the development of several nervous system ...

Kynurenine Promotes Phosphate-Induced Endothelial Calcification via Endothelial-to-Mesenchymal Transition, Osteoblastic Differentiation and AhR Activation

Toxins
In end-stage renal disease (ESRD), the accumulation of solutes normally excreted by the kidneys contributes to multiple complications, including vascular calcification (VC), a key factor in the heightened cardiovascular risk seen in these patients. Among

Kynurenines, neurodegeneration and Alzheimer’s disease [PDF]

Journal of Cellular and Molecular Medicine, 2010
Abstract Alzheimer’s disease The kynurenine pathway Relations of kynurenines to the pathomechanism of AD A future therapeutic approach: modulating the kynurenine pathway Concluding remarks Alzheimer’s disease (AD) is one of the major causes of dementia. The pathogenesis of the disease is not entirely understood, but the amyloid β peptide (Aβ) and the

Alzheimer’s Disease, Astrocytes and Kynurenines [PDF]

Current Alzheimer Research, 2015
Alzheimer's disease (AD) is an age-related neurodegenerative disease and the most common cause of dementia. The etiology of AD is not entirely clear and despite the increasing knowledge regarding the pathomechanism, no effective disease-modifying therapy is yet available.

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

Higher Circulating Kynurenine Levels Linked to Higher Risk of Sarcopenia in Older Adults: A Cohort Study and UK Biobank Analysis [PDF]

Endocrinology and Metabolism
Background While experimental studies show kynurenine, a tryptophan metabolite, drives muscle catabolism through pro-oxidative and inflammatory mechanisms, clinical evidence linking circulating kynurenine to sarcopenia in humans remains scarce.
