Methyl Canthin-6-one-2-carboxylate Inhibits the Activation of the NLRP3 Inflammasome in Synovial Macrophages by Upregulating Nrf2 Expression.

Rheumatoid arthritis (RA) is an autoimmune disorder that leads to severe cartilage deterioration and synovial impairment in the joints. Previous studies have indicated that the aberrant activation of the NLRP3 inflammasome in synovial macrophages plays a significant role in the pathogenesis of RA and has been regarded as a therapeutic target for the disease. In this study, we synthesized a novel canthin-6-one alkaloid, namely methyl canthin-6-one-2-carboxylate (Cant), and assessed its effects on NLRP3 inflammasome activation in macrophages.

Using peer narrative support to promote return to work for cancer survivors: a protocol study of action research.

Background: Chinese cancer survivors are not doing well in returning to work. Peer support, as an external coping resource to help cancer survivors return to work, brings together members of the lay community with similar stressors or problems for mutual support. Peer volunteers have not received systematic training, so inappropriate language in the support process can often cause secondary damage to both the peer and the cancer survivor.

Folic acid-modified ginger-derived extracellular vesicles for targeted treatment of rheumatoid arthritis by remodeling immune microenvironment via the PI3K-AKT pathway.

Rheumatoid arthritis (RA), a form of autoimmune inflammation, is marked by enduring synovial inflammation and the subsequent impairment of joint function. Despite the availability of conventional treatments, they are often marred by significant side effects and the associated high costs. Plant-derived extracellular vesicles (PEVs) offer a compelling alternative, owing to their abundant availability, affordability, low immunogenicity, high biocompatibility, and feasibility for large-scale production.

Ursonic Acid Ameliorates HO-Induced Oxidative Damage in PC12 Cells and Prolonged the Lifespan in C. elegans by Activating MAPKs/Nrf2/HO-1 Signaling Pathway.

Growing evidence suggests that plant compounds are emerging as a tremendous source for slowing the onset and progression of Alzheimer's disease (AD). Ursonic acid (UNA) is a naturally occurring pentacyclic triterpenoid with some hypoglycemic, anticancer, and antiinflammatory activities. However, the pharmacological effects of UNA on AD are still unknown.
