In vivo imaging of amyloid-beta deposits in mouse brain with multiphoton microscopy.
With the advent of transgenic mouse models expressing cortical amyloid pathology, the potential to study its progression in an intact brain has been realized. Multiphoton microscopy provides a non-destructive means of imaging with micron resolution up to 500 microm deep into the cortex. We detail a surgical procedure and discuss a multiphoton imaging approach that allows for labeling and chronic visualization of amyloid-beta deposits through a cranial window. The ability to monitor these hallmarks of Alzheimer's disease enables studies aimed at evaluating the efficacy of treatment and prevention strategies.
