Approach to the diagnosis and management of dysbiosis

Frontiers in Nutrition
All microorganisms like bacteria, viruses and fungi that reside within a host environment are considered a microbiome. The number of bacteria almost equal that of human cells, however, the genome of these bacteria may be almost 100 times larger than the ...

Cystic Fibrosis-Related Gut Dysbiosis: A Systematic Review

, 2023
Background and Aims Cystic Fibrosis (CF) is associated with gut dysbiosis, local and systemic inflammation, and impaired immune function. Gut microbiota dysbiosis results from changes in the complex gut milieu in response to CF transmembrane ...

Bifidobacterium Pseudolongum‐Derived Inosine Mitigates Polystyrene Nanoplastics‐Induced Hepatic Injury by Inhibiting the Polarization of M1 Macrophages

Advanced Science, EarlyView.
Probiotic B.p colonization elevated gut‐derived inosine level in the liver, while elevated inosine activated A2AR and subsequently blocked NPs‐induced polarization of M1 macrophages by repressing the miR155/SOCS1/NF‐κB pathway. This reduced the release of inflammatory cytokines and thereby, mitigated NPs‐induced hepatic injury.

Multi-modal Single-Cell Analysis Reveals Brain Immune Landscape Plasticity during Aging and Gut Microbiota Dysbiosis

Cell Reports, 2020
Summary: Phenotypic and functional plasticity of brain immune cells contribute to brain tissue homeostasis and disease. Immune cell plasticity is profoundly influenced by tissue microenvironment cues and systemic factors.

Oral Prebiotic Polysaccharide Hydrogels Sustaining Colon Antibody Release Alleviate Inflammatory Bowel Disease

Advanced Science, EarlyView.
An orally administered prebiotic polysaccharide hydrogel (predaGel) based on inulin and alginate‐dopamine is stable in the stomach, adheres to the intestine, and degrades slowly in the colon. It enables site‐specific delivery of anti‐TNF‐α and anti‐IL‐12/23 antibodies, scavenges reactive oxygen species, and remodels gut microbiota, offering effective ...

Signature of Microbial Dysbiosis in Periodontitis

, 2017
International audiencePeriodontitis is driven by disproportionate host inflammatory immune responses induced by an imbalance in the composition of oral bacteria; this instigates microbial dysbiosis, along with failed resolution of the chronic destructive
