Human Colitis‐on‐Chip Model Reveals Dual Roles of Butyrate in Epithelial and Macrophage Defense Against Candida albicans Tissue Invasion

Small, EarlyView.
This study establishes a human immunocompetent colitis‐on‐chip model that mimics inflamed gut mucosa and enables quantitative analysis of Candida albicans tissue invasion under DSS‐induced injury. It reveals that microbiota‐derived butyrate simultaneously stabilizes epithelial junctions and reprograms macrophages via HDAC/NLRP3‐dependent mechanisms ...

How holobionts get sick—toward a unifying scheme of disease

Microbiome, 2017
All humans, animals, and plants are holobionts. Holobionts comprise the host and a myriad of interacting microorganisms—the microbiota. The hologenome encompasses the genome of the host plus the composite of all microbial genomes (the microbiome).

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Image_3_Absence of Bacteria Permits Fungal Gut-To-Brain Translocation and Invasion in Germfree Mice but Ageing Alone Does Not Drive Pathobiont Expansion in Conventionally Raised Mice.tif

, 2022
Age-associated changes in the structure of the intestinal microbiome and in its interaction with the brain via the gut-brain axis are increasingly being implicated in neurological and neurodegenerative diseases.

Periodontitis and Endotoxemia: Clinical and Microbiological Insights

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim Endotoxemia has been proposed as a link between periodontitis and systemic complications through the translocation of lipopolysaccharide (LPS) from inflamed periodontal sites into the bloodstream. This study aimed to investigate subgingival and serum LPS activities and their correlations with periodontal clinical and microbiological ...

The Role of Viruses in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
This narrative review aimed to summarize current evidence on the presence and potential pathogenic role of viruses in periodontitis. Design: Narrative Review; Population: Patients with periodontitis; Exposure: Detection of viruses in oral samples (biopsies, saliva, gingival crevicular fluid, subgingival plaque, blood); Outcome: Viral prevalence, load ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Keystone pathobionts associated with colorectal cancer promote oncogenic reprograming.

PLoS ONE
Fusobacterium nucleatum (Fn) and enterotoxigenic Bacteroides fragilis (ETBF) are two pathobionts consistently enriched in the gut microbiomes of patients with colorectal cancer (CRC) compared to healthy counterparts and frequently observed for their ...
