Manganese induces neuroinflammation through SPON1-mediated activation of ERK1/2/NF-κB pathway.

Excessive accumulation of manganese (Mn) can cause neuroinflammation, impairing cognitive function. SPON1, a secreted glycoprotein in the extracellular matrix, is implicated in neuroinflammation, but its role in activating pro-inflammatory pathways in Mn-induced neuroinflammation remains unclear. This study employed in vivo and in vitro models to investigate Mn neuroinflammation.

Blueberry anthocyanins ameliorate arsenic-induced cognitive impairment in rats: mitigating mitochondrial damage and dysregulation.

Anti-IL-17 Inhibits PINK1/Parkin Autophagy and M1 Macrophage Polarization in Rheumatic Heart Disease.

Rheumatic heart disease (RHD) is an important and preventable cause of cardiovascular death and disability, but the lack of clarity about its exact mechanisms makes it more difficult to find alternative methods or prevention and treatment. We previously demonstrated that increased IL-17 expression plays a crucial role in the development of RHD-related valvular inflammatory injury. Macrophage autophagy/polarization may be a pro-survival strategy in the initiation and resolution of the inflammatory process.
