Yang et al. found that in astrocytes pretreated with PBMt, the typical Aβ-induced production of ROS and inflammatory response were eliminated in the cortical astrocytes of rats.56 PBMt has also demonstrated influence on the glial response, particularly that of the astrocytes, in a monkey model of Parkinson's disease.57 Sun et al. found that PBMt applied to the spinal cord of rats after SCI inhibited activation of GFAP-positive astrocytes as well as inhibited astrocyte proliferation and the expression of astrocyte activation-related genes in vitro. Here, GFAP is linked to Parkinson disease.
