Wu et al. documented that in a mouse model of Alzheimer’s disease, the levels of IFN-γ and IL-10 in neural stem cells and T lymphocytes were upregulated following PBMT treatment (λ = 635 nm, energy density of 2 J/cm2, for 10 min daily for one month), which resulted in the alleviation of cognitive deficits24. This evidence concerns the gene IFNG and Alzheimer disease.
