Abstract

We previously reported that Alzheimer-related pathology in cerebral cortex of APP/PS1 and K3 tau transgenic mouse strains is mitigated by near infrared light (NIr). Here, we extend these observations to the cerebellum. One month of NIr treatment mitigated the deposition of β-amyloid in cerebellar cortex of APP/PS1 mice, and the formation of neurofibrillary tangles, the hyperphosphorylation of tau, the damage caused by oxidative stress and the downregulation of cytochrome oxidase expression by Purkinje cells in the cerebellar cortex of K3 mice. These findings show the ability of NIr to mitigate degeneration in many - probably all - regions of the mouse brain.
