Hepatoma cell density promotes claudin-1 and scavenger receptor BI expression and hepatitis C virus internalization. [PDF]

, 2009
Hepatitis C virus (HCV) entry occurs via a pH- and clathrin-dependent endocytic pathway and requires a number of cellular factors, including CD81, the tight-junction proteins claudin 1 (CLDN1) and occludin, and scavenger receptor class B member I (SR-BI).

CRP Deficiency Rescues Periodontitis‐Induced Hippocampal Neurogenesis Impairment by Suppressing OPC‐Derived BMP4 Signaling in Rats

Advanced Science, EarlyView.
Chronic periodontitis elevates circulating CRP, which enters the hippocampus to upregulate BMP4 in oligodendrocyte precursor cells (OPCs), thereby impairing neurogenesis and inducing anxiety/depression‐like behaviors in rats. Counteracting this pathway, CRP deficiency helps confer functional resilience to OPCs.

Diet supplementation with an organic acids-based formulation affects gut microbiota and expression of gut barrier genes in broilers

Animal Nutrition, 2018
This study was designed to study the effect of diet supplementation with an organic acids-based formulation (OABF) on luminal- and mucosa-associated bacteria, concentration of volatile fatty acids (VFA), microbial glycolytic enzyme activity and ...

Polyubiquitination and SUMOylation Sites Regulate the Stability of ZO-2 Protein and the Sealing of Tight Junctions

Cells, 2022
Tight junctions (TJs) regulate the transit of ions and molecules through the paracellular pathway in epithelial cells. Zonula occludens 2 (ZO-2) is a cytoplasmic TJ protein.

Convergence of Wnt signalling on the HNF4a-driven transcription in controlling liver zonation [PDF]

, 2009
BACKGROUND & AIMS: In each hepatocyte, the specific repertoire of gene expression is influenced by its exact location along the portocentrovenular axis of the hepatic lobule and provides a reason for the liver functions compartmentalization defined ...

Protection and Delivery of Phytochemicals from Passive Encapsulation to Guaranteed Self‐Assembly Induced by Amyloid Template for Chronic Disease Prevention via Modulating Microbial‐Host Crosstalk

Advanced Science, EarlyView.
ABSTRACT The rising incidence of chronic diseases globally has drawn widespread attention to phytochemicals, which exert targeted preventive and alleviating effect by modulating gut microbiota; thus, a potential strategy for precision nutritional interventions is offered.

AII amacrine cells discriminate between heterocellular and homocellular locations when assembling connexin36-containing gap junctions [PDF]

, 2014
Electrical synapses (gap junctions) rapidly transmit signals between neurons and are composed of connexins. In neurons, connexin36 (C×36) is the most abundant isoform; however, the mechanisms underlying formation of C×36-containing electrical synapses ...

Diabetes Mellitus Facilitates Gallstone Formation Through CXCR2‐NETs–Mediated Liver‐Bile Barrier Damage

Advanced Science, EarlyView.
Diabetes is an independent risk factor for gallstones. It upregulates CXCR2 expression in hepatic neutrophils, stimulating the formation of NETs that disrupt hepatocellular tight junctions and the liver‐bile barrier. NETs enter bile to accelerate gallstone development, while sarcosine inhibits CXCR2 and NETs production, effectively reducing diabetes ...

Oral Celastrol Nanomedicine Targeting Intestinal Antigen‐Presenting Cells to Effectively Mitigate Autoimmune Uveitis via Gut‐Retina Axis

Advanced Science, EarlyView.
Oral nanoCEL exhibits effective intestinal targeting of antigen‐presenting cells and restores the Th17/Treg balance in lymph nodes and spleen, ultimately protecting the blood‐retinal barrier by inhibiting peripheral immune cell infiltration and suppressing retinal glial cell activation.
