A novel in vitro platform for the study of SN38-induced mucosal damage and the development of Toll-like receptor 4-targeted therapeutic options [PDF]

open access: yes, 2016
Tight junction and epithelial barrier disruption is a common trait of many gastrointestinal pathologies, including chemotherapy-induced gut toxicity. Currently, there are no validated in vitro models suitable for the study of chemotherapy-induced mucosal

Rol de las uniones estrechas del epitelio intestinal en la patogenia de la enfermedad de Crohn

open access: yesAnales de la Facultad de Medicina, 2015
Crohn’s disease is an inflammatory bowel disease that affects the intestinal wall. This wall consists of an epithelial cell layer that forms a continuous polarized monolayer, closely connected by various types of cellular junctions.

Polarization Induced Switching Effect in Graphene Nanoribbon Edge-Defect Junction

open access: yes, 2009
With nonequilibrium Green's function approach combined with density functional theory, we perform an ab initio calculation to investigate transport properties of graphene nanoribbon junctions self-consistently.

Glial Cells in the Fish Retinal Nerve Fiber Layer Form Tight Junctions, Separating and Surrounding Axons

open access: yesFrontiers in Molecular Neuroscience, 2018
In the retina of teleost fish, cell addition continues throughout life involving proliferation and axonal growth. To study how this is achieved in a fully functioning retina, we investigated the nerve fiber layer (NFL) of the cichlid fish Astatotilapia ...

Tight-binding study of interface states in semiconductor heterojunctions

open access: yes, 2001
Localized interface states in abrupt semiconductor heterojunctions are studied within a tight-binding model. The intention is to provide a microscopic foundation for the results of similar studies which were based upon the two-band model within the ...

Caveolin1 Is Required for Th1 Cell Infiltration, but Not Tight Junction Remodeling, at the Blood-Brain Barrier in Autoimmune Neuroinflammation

open access: yesCell Reports, 2017
Lymphocytes cross vascular boundaries via either disrupted tight junctions (TJs) or caveolae to induce tissue inflammation. In the CNS, Th17 lymphocytes cross the blood-brain barrier (BBB) before Th1 cells; yet this differential crossing is poorly ...

ZOning out Tight Junctions [PDF]

open access: yesCell, 2006
The tight junction is an intricate seal between adjoining epithelial cells that also separates the apical and basolateral membranes within these cells. A paper in this issue of Cell by Umeda et al. (2006) demonstrates that loss of the ZO scaffolding proteins prevents the formation of tight junctions but surprisingly does not perturb apico-basal ...

The effect of nearest neighbor spin-singlet correlations in conventional graphene SNS Josephson junctions

open access: yes, 2009
Using the self-consistent tight-binding Bogoliubov-de Gennes formalism we have studied the effect of nearest neighbor spin-singlet bond (SB) correlations on Josephson coupling and proximity effect in graphene SNS Josephson junctions with conventional s ...

The Josephson current in Fe-based superconducting junctions: theory and experiment [PDF]

open access: yes, 2015
We present theory of dc Josephson effect in contacts between Fe-based and spin-singlet $s$-wave superconductors. The method is based on the calculation of temperature Green's function in the junction within the tight-binding model. We calculate the phase

Monitoring of Cell Layer Integrity with a Current-Driven Organic Electrochemical Transistor

open access: yes, 2019
The integrity of CaCo-2 cell barriers is investigated by organic electrochemical transistors (OECTs) in a current-driven configuration. Ion transport through cellular barriers via the paracellular pathway is modulated by tight junctions between adjacent ...
