Medin amyloid forms age‐associated aggregates in the brain vasculature and may contribute to cerebral β‐amyloidosis

Glycogen synthase kinase-3β may contribute to neuroprotective effects of Sargassum oligocystum against amyloid-beta in neuronal SH-SY5Y cells

Glycogen synthase kinase (GSK)-3β mediates amyloid-beta (Aβ) and oxidative stress-induced neurotoxicity in neurodegenerative disorders. Natural products with antioxidant activity, such as Sargassum (S.) oligocystum may modulate GSK-3β enzyme and protect against Aβ-induced neurotoxicity. Therefore, we aimed to assess the neuroprotective effects of a methanolic extract of S. oligocystum against A...

Smooth muscle titin forms in vitro amyloid aggregates

Amyloids are insoluble fibrous protein aggregates, and their accumulation is associated with amyloidosis and many neurodegenerative diseases, including Alzheimer's disease. In the present study, we report that smooth muscle titin (SMT; 500 kDa) from chicken gizzard forms amyloid aggregates in vitro This conclusion is supported by EM data, fluorescence analysis using thioflavin T (ThT), Congo re...

Studies on medin amyloid formation and involvement in aortic pathology

Decreased serum level of lipoxin A4 (LXA4) may contribute to the pathogenesis of allergic rhinitis

Background: Rhinitis is a prevalent chronic inflammatory disease of the nasal mucosa. Arachidonic acid-derived lipoxin A4 (LXA4) has long been recognized to exert crucial anti-inflammatory and pro-resolving effects on inflammatory responses through a specific receptor named formyl peptide receptor-2 (FPR2). This study aimed to determine the serum level of LXA4 as well as the relative mRNA expre...

How astrocyte networks may contribute to cerebral metabolite clearance

The brain possesses an intricate network of interconnected fluid pathways that are vital to the maintenance of its homeostasis. With diffusion being the main mode of solute transport in cerebral tissue, it is not clear how bulk flow through these pathways is involved in the removal of metabolites. In this computational study, we show that networks of astrocytes may contribute to the passage of ...
