| In vivo study | In the first 3 months of the MWM test, the mean latency of Trihexyphenidyl(THP)-treated rats was significantly prolonged, and at 4-6 months, the behavioral deficit was repaired. Genes significantly down-regulated by THP are those associated with immune response, antigen processing and presentation, and major histocompatibility complex. In the aging brain, the treatment of THP reduces the expression of MHC class I. Long-term treatment of THP makes the hippocampus and cortical microglia in the motor area of rat frontal cortex change the inflammatory phenotype, structural changes. |
