Neuroinflammation remains a central piece in Parkinson's disease (PD) pathophysiology. However, mechanisms by which PD links to the neuroinflammation remain elusive. Here, for the first time, we report that lower dose of niacin in PD patients may affect macrophage polarization from M1 (pro-inflammatory) to M2 (counter-inflammatory) profile through the niacin receptor GPR109A. Skew in the peripheral macrophages were accompanied by improved quality of life assessments in patients. Low dose niacin supplementation may be beneficial in PD, boosting anti-inflammatory processes and suppressing inflammation. Varied niacin dosages for longer durations may further reveal the potential role of anti-inflammatory interventions in PD progression.

CO-loaded hemoglobin/EGCG nanoparticles functional coatings for inflammation modulation of vascular implants.

Regen Biomater

December 2024

Institute of Biomedical Engineering, College of Medicine, Southwest Jiaotong University, Chengdu, Sichuan 610031, China.

During the implantation process of cardiovascular implants, vascular damage caused by inflammation occurs, and the inflammatory process is accompanied by oxidative stress. Currently, carbon monoxide (CO) has been demonstrated to exhibit various biological effects including vasodilatation, antithrombotic, anti-inflammatory, apoptosis-inducing and antiproliferative properties. In this study, hemoglobin/epigallocatechin-3-gallate (EGCG) core-shell nanoparticle-containing coating on stainless steel was prepared for CO loading and inflammation modulation.

MDA5+ DM, or anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis (DM), is a rare autoimmune illness that primarily affects women of Asian origin. The typical presentation of MDA5+ DM includes a variety of cutaneous lesions accompanied by either no muscular weakness (amyopathic) or hypomyopathic features. In patients with MDA5+ DM, rapid progression of interstitial lung disease is a frequent manifestation associated with poor prognosis.

The controllable regulation of immune and osteogenic processes plays a critical role in the modification of biocompatible materials for tissue regeneration. In this study, titanium dioxide-europium coatings (MAO/Eu) were prepared on the surface of a titanium alloy (Ti-6Al-4V) a one-step process combining microarc oxidation (MAO) and doping. The incorporation of Eu significantly improved the hydrophilic and mechanical properties of the TiO coatings without altering their morphology.

C3AR1 as a target for preeclampsia: from bioinformatics and network pharmacology to experimental validation.

BMC Pregnancy Childbirth

January 2025

Obstetrics and Gynecology Center, Department of Gynecology, Zhujiang Hospital, Southern Medical University, Guangzhou, Guangdong, 510280, China.

Background: Preeclampsia, characterized by hypertension and proteinuria during pregnancy, poses significant risks to both mother and fetus. The complement system's aberrant activation, notably the C3AR1, is important to the pathogenesis of preeclampsia, although the precise mechanisms are not fully understood.

Materials And Methods: Utilizing the Comparative Toxicogenomics Database (CTD) and Molecular Signatures Database (MSigDB), we identified complement system targets associated with preeclampsia and environmental pollutants.
