Amyloid-β modulates the phase separation and aggregation of α-synuclein
The aggregation of amyloid-β (Aβ) and α-synuclein (αSyn) into insoluble proteinaceous deposits is a hallmark of Alzheimer's and Parkinson's diseases. Recent evidence suggests that these amyloidogenic proteins act in synergy, with their coaggregation frequently observed in these disorders. In this study, we investigate the interaction of Aβ and αSyn using various biophysical tools. In particular, we explore the cocondensation of Aβ with αSyn, elucidating the pathways through which Aβ modulates...
Senescence Alters Antimicrobial Peptide Expression and Induces Amyloid-beta Production in Retinal Pigment Epithelial Cells
Age-related retinal degeneration, such as diabetic retinopathy and age-related macular degeneration, are major causes of blindness in modern society. Recent studies suggest that dysbiosis and intraocular translocation of bacteria from the blood circulation are critically involved in retinal degeneration. We hypothesise that the blood-retinal barrier (BRB) cells can protect the neuroretina from blood-borne pathogens by producing antimicrobial peptides (AMPs). The antimicrobial activity may...
