Role of Homeobox A1 in Airway Epithelial Generation from Human Airway Basal Cells

Cells
Airway basal cells from chronic obstructive pulmonary disease patients show a reduction in HOXA1 expression and generate an abnormal airway epithelium.

Role of subclinical gut inflammation in the pathogenesis of spondyloarthritis [PDF]

, 2018
Subclinical gut inflammation occurring in patients affected by spondyloarthritis (SpA) is correlated with the severity of spine inflammation. Several evidences indicate that dysbiosis occurs in SpA, and that may modulate intestinal permeability and ...

Connexin-Occludin Chimeras Containing the Zo-Binding Domain of Occludin Localize at Mdck Tight Junctions and Nrk Cell Contacts [PDF]

The Journal of Cell Biology, 1999
Occludin is a transmembrane protein of the tight junction that functions in creating both an intercellular permeability barrier and an intramembrane diffusion barrier. Creation of the barrier requires the precise localization of occludin, and a distinct family of transmembrane proteins called claudins, into continuous linear fibrils visible by freeze ...

An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

Advanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

A Simulated Microgravity Environment Causes a Sustained Defect in Epithelial Barrier Function. [PDF]

, 2019
Intestinal epithelial cell (IEC) junctions constitute a robust barrier to invasion by viruses, bacteria and exposure to ingested agents. Previous studies showed that microgravity compromises the human immune system and increases enteropathogen virulence.

Peripheral Inflammation Enhances Microglia Response and Nigral Dopaminergic Cell Death in an in vivo MPTP Model of Parkinson’s Disease [PDF]

, 2018
The impact of systemic inflammation in nigral dopaminergic cell loss remains unclear. Here, we have investigated the role of peripheral inflammation induced by systemic lipopolysaccharide (LPS) administration in the MPTP-based model of Parkinson’s ...

Possible Involvement of Phosphorylation of Occludin in Tight Junction Formation [PDF]

The Journal of Cell Biology, 1997
Occludin is an integral membrane protein localizing at tight junctions in epithelial and endothelial cells. Occludin from confluent culture MDCK I cells resolved as several (>10) bands between 62 and 82 kD in SDS-PAGE, of which two or three bands of the lowest Mr were predominant.

The Enhanced Whey Protein Oral Bioavailability and Muscle Anabolism Ability by a Simple and Effective Piperine‐Whey Protein Synergistic Codelivery System

Advanced Science, EarlyView.
WP(Pip) is a mixture of whey protein and piperine‐loaded nanoemulsion stabilized by WP through microfluidic homogenization. Acting as a “smart key,” piperine opens epithelial tight junctions to enhance absorption of whey protein and, thereby increasing circulating amino acid availability, synergistically up‐regulates the mTOR signaling pathway in ...

Collagen prolyl 4-hydroxylase subunit α member-induced head and neck squamous cell carcinoma aggressiveness is antagonized by LLGL2 via reduced expression of occludin

Acta Biochimica et Biophysica Sinica
There are three isoforms of human collagen prolyl 4-hydroxylases (C-P4Hs), each of which has been reported to play an important role in regulating the progression of a variety of human cancers. By analyzing TGCA

Tight Junctions Go Viral!

Viruses, 2015
Tight junctions (TJs) are highly specialized membrane domains involved in many important cellular processes such as the regulation of the passage of ions and macromolecules across the paracellular space and the establishment of cell polarity in ...
