Integration of 168,000 samples reveals global patterns of the human gut microbiome

Cell, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

The factors shaping human microbiome variation are a major focus of biomedical research. While other fields have used large sequencing compendia to extract insights requiring otherwise impractical sample sizes, the field has lacked comparably sized resource for 16S rRNA gene amplicon commonly quantify composition. To address this gap, we processed 168,464 publicly available gut samples with uniform pipeline. We use compendium evaluate geographic and technical effects on variation. find that regions such as Central Southern Asia differ significantly from more thoroughly characterized microbiomes Europe Northern America composition alone can be predict sample's region origin. also strong associations between primers DNA extraction. anticipate growing work, Human Microbiome Compendium, will enable advanced applied methodological

Dietary Polyphenols and Gut Microbiota Cross-Talk: Molecular and Therapeutic Perspectives for Cardiometabolic Disease: A Narrative Review

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(16), С. 9118 - 9118

Опубликована: Авг. 22, 2024

The intricate interplay between the gut microbiota and polyphenols has emerged as a captivating frontier in understanding potentially harnessing therapeutic potential of these bioactive compounds. Phenolic compounds, renowned for their antioxidant, anti-inflammatory, antidiabetic, anticancer properties, are subject to transformations within milieu, where diverse microbial ecosystem exerts profound effects on metabolism bioavailability. Conversely, exhibit remarkable capacity modulate composition activity microbiota, fostering bidirectional relationship that extends beyond mere nutrient processing. This symbiotic interaction holds significant implications human health, particularly cardiometabolic diseases such diabetes mellitus, metabolic-dysfunction-associated steatotic liver disease, cardiovascular disease. Through comprehensive exploration molecular interactions, this narrative review elucidates reciprocal dynamics polyphenols, unveiling novel avenues intervention disorders. By unravelling cross-talk two entities, underscores multifaceted roles overall health pivotal role modulation promising strategy mitigating burden diseases.

Diversity in women and their vaginal microbiota

Trends in Microbiology, Год журнала: 2025, Номер unknown

Опубликована: Фев. 1, 2025

Abstract

Women's health is essential to global societal and economic wellbeing, yet disparities remain prevalent. The vaginal microbiota plays a critical role in health, with research indicating that reduced levels of core bacteria, such as lactobacilli, are associated conditions like bacterial vaginosis (BV) increased infection susceptibility. Lower lactobacilli reported more frequently women African Latin American descent compared European Asian descent. However, geographical other study inclusion analysis biases influence current research. This opinion highlights the need for comprehensive understanding 'healthy' microbiome. It underscores efforts broaden on microbiome diversity socially relevant contexts, avoiding inappropriate applications terms race ethnicity.

The microbiota-gut-brain-immune interface in the pathogenesis of neuroinflammatory diseases: a narrative review of the emerging literature

Frontiers in Immunology, Год журнала: 2024, Номер 15

Importance Research is beginning to elucidate the sophisticated mechanisms underlying microbiota-gut-brain-immune interface, moving from primarily animal models human studies. Findings support dynamic relationships between gut microbiota as an ecosystem (microbiome) within (host) and its intersection with host immune nervous systems. Adding this effects on epigenetic regulation of gene expression further complicates strengthens response.

The Effect of Microbiome-Derived Metabolites in Inflammation-Related Cancer Prevention and Treatment

Biomolecules, Год журнала: 2025, Номер 15(5), С. 688 - 688

Опубликована: Май 8, 2025

Chronic inflammation plays a crucial role in cancer development, yet the mechanisms linking microbiome to inflammation-related carcinogenesis remain unclear. Emerging evidence suggests that microbiome-derived metabolites influence inflammatory pathways, presenting both challenges and opportunities for therapy. However, deeper understanding of how these regulate contribute prevention is still needed. This review explores recent advances their roles carcinogenesis. It highlights key molecular mechanisms, emerging therapies, unresolved challenges. Synthesizing current research, including clinical trials experimental models, bridges gap between science Microbial such as short-chain fatty acids (SCFAs), polyamines, indoles, bile play vital regulating suppressing cancer. Many exhibit potent anti-inflammatory immunomodulatory effects, demonstrating therapeutic potential. Case studies show promising results, but metabolite stability, bioavailability, individual variability remain. Understanding microbiome–metabolite interactions offers novel strategies treatment. identifies knowledge gaps proposes future research directions harness innovative therapies. Addressing issues may pave way microbiome-targeted interventions.

Abstract The human gut microbiome is a modifier of the risk for many non‐communicable diseases throughout lifespan. In ageing, effect appears to be more pronounced because lower physiological reserve. Microbial metabolites and other bioactive products act upon some key processes involved in Hallmarks Ageing. Dietary interventions that delay age‐related change have also led delayed onset ageing‐related health loss, improved levels cognitive function, inflammatory status frailty. Cross‐sectional analysis thousands datasets from around world has identified taxa are depleted during accelerated become abundant, but these signatures differ geographical regions. challenges research this area experimentally prove particular species or strains directly contribute health‐related ageing outcomes, develop practical ways retaining re‐administering them on population basis. promotion health‐associated mirrors challenge maintaining planetary microbial ecosystems face anthropogenic effects climate change. Lessons learned acting at individual level can inform microbiome‐targeting strategies achieving Sustainable Development Goals global level.

Abstract The neonatal microbiome has been the focus of considerable research over past two decades and studies have added fascinating information in terms early microbial patterns how these relate to various disease processes. One difficulty with interpretation relationships is that such data associative provides little proof causality or underpinning mechanisms. Integrating other omics as proteome, inflammatory mediators, metabolome an emerging approach address this gap. Here we discuss omics, their integration, they can be applied improve our understanding, treatment, prevention disease. Impact This review introduces concept multiomics neonatology technologies integrated We highlight considerations for performing multiomic neonates need validation separate cohorts and/or relevant model systems. summarise use expanding lay out steps bring clinic enable precision medicine.
