CD83 mediates the inhibitory effect of the S1PR1 agonist CYM5442 on LPS-induced M1 polarization of macrophages through the ERK-STAT-1 signaling pathway.

Macrophages possess M1/M2 polarization, which perform an essential role in immunology and inflammation studies. However, few studies have investigated the specific molecules involved in the polarization process beyond its induction and characterization. Here, we determined that the molecule S1PR1 regulates M1 polarization in macrophages and that the surface marker CD83 is involved in this process.

Mesenchymal Stem Cell-derived Type II Alveolar Epithelial Progenitor Cells Attenuate LPS-induced Acute Lung Injury and Reduce P63 Expression.

Aim: Acute respiratory distress syndrome (ARDS)/acute lung injury (ALI) is a severe clinical respiratory-failure disease mainly characterized by acute damage to the alveolar epithelium and pulmonary vascular endothelial cells.

Targeting the NCOA3-SP1-TERT axis for tumor growth in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) has a high mortality rate and lacks an effective therapeutic target. Elevated expression of human telomerase reverse transcriptase (TERT) is an important hallmark in cancers, but the mechanism by which TERT is activated differentially in cancers is poorly understood. Here, we have identified nuclear receptor coactivator-3 (NCOA3) as a new modulator of TERT expression and tumor growth in HCC.

Surface Modification of Microfluidic Blood-Brain-Barriers for Improved Screening of Small Molecules and Nanoparticles.

Here, we have developed and evaluated a microfluidic-based human blood-brain-barrier (μBBB) platform that models and predicts brain tissue uptake of small molecule drugs and nanoparticles (NPs) targeting the central nervous system. By using a photocrosslinkable copolymer that was prepared from monomers containing benzophenone and -hydroxysuccinimide ester functional groups, we were able to evenly coat and functionalize μBBB chip channels , providing a covalently attached homogenous layer of extracellular matrix proteins. This novel approach allowed the coculture of human endothelial cells, pericytes, and astrocytes and resulted in the formation of a mimic of cerebral endothelium expressing tight junction markers and efflux proteins, resembling the native BBB.

Preclinical Nanomedicines for Polyglutamine-Based Neurodegenerative Diseases.

Polyglutamine (polyQ) diseases, such as Huntington's disease and several types of spinocerebellar ataxias, are dominantly inherited progressive neurodegenerative disorders and characterized by the presence of expanded trinucleotide repeats in the respective disease locus of the patient genomes. Patients with polyQ diseases currently need to rely on symptom-relieving treatments because disease-modifying therapeutic interventions remain scarce. Many disease-modifying therapeutic agents are now under clinical testing for treating polyQ diseases, but their delivery to the brain is often too invasive (e.
