Extracellular nicotinate phosphoribosyltransferase binds Toll like receptor 4 and mediates inflammation

Nature Communications, 2019
The enzyme nicotinate phosphoribosyltransferase (NAPRT) mediates the rate-limiting step in NAD salvage pathway starting from nicotinic acid. Here the authors show that NAPRT can be detected extracellularly, binds to Toll like receptor 4, and activates NF-

Immune Cell Toll-like Receptor 4 Mediates the Development of Obesity- and Endotoxemia-Associated Adipose Tissue Fibrosis

Cell Reports, 2014
Adipose tissue fibrosis development blocks adipocyte hypertrophy and favors ectopic lipid accumulation. Here, we show that adipose tissue fibrosis is associated with obesity and insulin resistance in humans and mice.

A Robust Heparin‐Mimicking Polyglycerol‐Based Coating for Blood‐Contacting Devices with Long‐Term Hemocompatibility and Preliminary Anti‐Inflammatory Properties

Advanced Healthcare Materials, EarlyView.
A robust heparin‐mimicking coating based on sulfated polyglycerol is constructed via layer‐by‐layer assembly on bloodcontacting surfaces. The coating exhibits long‐term anticoagulant and anti‐inflammatory properties by resisting protein adsorption, preventing platelet activation, and suppressing immune responses, offering a promising strategy for ...
