Gut Dysbiosis and Neurobehavioral Alterations in Rats Exposed to Silver Nanoparticles

, 2017
Due to their antimicrobial properties, silver nanoparticles (AgNPs) are being used in non-edible and edible consumer products. It is not clear though if exposure to these chemicals can exert toxic effects on the host and gut microbiome.

Tissue‐Resident Macrophage‐Derived E3 Ligase SMURF2 Restricts Autoimmune Inflammation by Mediating the Degradation of p‐TBK1

Advanced Science, EarlyView.
Dysregulated Tissue resident macrophage (TRMs) link to autoimmune inflammation. SMURF2 mediates Lys‐27 (K27)‐linked ubiquitination of p‐TBK1 and its degradation, which inhibits CSF1R signaling‐triggered TRM proliferation, thereby restraining the autoimmune inflammation.

Taurocholic Acid Is Associated With Disturbed Functional Connectivity in the Hippocampus of Patients With Depression

Advanced Science, EarlyView.
This study identifies elevated taurocholic acid (TCA) in Major Depressive Disorder patients. Gut microbiome‐associated TCA impairs hippocampal neurogenesis, triggers microglia activation, and elicits depression‐like behavior in mice via the S1PR2. In patients, functional neuroimaging reveals that serum TCA levels correlate with altered functional ...

“Expanding the Lactococcal Cell Wall Polysaccharide Paradigm: Novel Structures and Metabolic Pathways in the Emerging Dairy Species Pseudolactococcus laudensis and Pseudolactococcus raffinolactis”

MicrobiologyOpen
Cell surface‐associated polysaccharides, including cell wall polysaccharides (CWPSs), capsular polysaccharides (CPSs), and exopolysaccharides (EPSs), play vital roles in bacterial interactions with their environment, influencing critical aspects of dairy

Microenvironment Self‐Adaptive Nanoarmor to Address Adhesion‐ and Colonization‐Related Obstacles in Impaired Intestine Promote Bacteriotherapy Against Parkinson's Disease

Advanced Science, EarlyView.
A microenvironment self‐adaptive nanoarmor is developed to effectively address the adhesion‐ and colonization‐related challenges posed by multiple physiological and pathological characteristics in the intestine. L. plantarum@MPN@CS showed significant therapeutic potential in treating Parkinson's disease (PD), a model for extraintestinal disorders, as ...

Importance of good hosting: reviewing the bi-directionality of the microbiome-gut-brain-axis

Frontiers in Neuroscience
Gut microorganisms have been shown to significantly impact on central function and studies that have associated brain disorders with specific bacterial genera have advocated an anomalous gut microbiome as the pathophysiological basis of several ...

Conformable Device for Independent Measurements of Mucosal and Vascular Barriers in a Complex In Vitro Intestinal Model

Advanced Science, EarlyView.
Development of more complex in vitro models necessitates the development of improved monitoring approaches. This work demonstrates a novel conformable device capable of measuring the resistance of two cell barriers within a single model independently, a significant advantage over conventional trans‐epithelial/endothelial electrical resistance (TEER ...

The gut microbiome: Relationships with disease and opportunities for therapy. [PDF]

, 2019
Over the past decade, our view of human-associated microbes has expanded beyond that of a few species toward an appreciation of the diverse and niche-specialized microbial communities that develop in the human host with chronological age.

Gut Microbiome Regulation of Gut Hormone Secretion

Endocrinology
Abstract The gut microbiome, comprising bacteria, viruses, fungi, and bacteriophages, is one of the largest microbial ecosystems in the human body and plays a crucial role in various physiological processes. This review explores the interaction between the gut microbiome and enteroendocrine cells (EECs), specialized hormone-secreting ...

Elemene Augments the Effects of Anti‐PD‐1 Immunotherapy on Hepatocellular Carcinoma by Regulating the miR‐130a‐5p/SPP/MHC‐I Axis

Advanced Science, EarlyView.
Elemene increases SPP expression by competitively binding with miR‐130a‐5p to suppress SPP mRNA degradation. This led to more antigen/MHC‐I complexes being expressed on the cell surface, which consequently facilitated the recognition and killing of HCC cells by CTLs and enhancing the antitumor immune efficacy of anti‐PD‐1.
