Retinal Amyloid Clearance Enhanced by 40-Hz Light Flicker via MHC-II + Microglia Regulation in Mice

Key Points

• To investigate the effect of 40-Hz light flicker on retinal microglial clearance of Aβ oligomers and the role of MHC-II expression.
• Utilized a mouse model to observe retinal responses to 40-Hz light flicker.
• Measured levels of Aβ oligomers in retinal tissue after exposure to light flicker.
• Assessed MHC-II expression on microglia post intervention.
• Confirmed that 40-Hz light flicker significantly enhances the clearance of Aβ oligomers in the retina.
• Observed upregulation of MHC-II expression on microglia following light flicker exposure.
• Indicated potential for 40-Hz light flicker as a non-invasive treatment for retinal disorders.
