It was widely accepted,in the present studies on the exact pathogenesis of anxiety disorders,that there is injury of hippocampal neurons in brain. Overseas studies indicate that injury play an important role in the regulation of protein phosphatase 2A( protein phosphatase 2A,PP2A) and the expression of α-synuclein( α-synuclein). Therefore,we consider that the change in the activity of PP2 A may induce the abnormal expression ofα-syn,causing relative changes in neurons; so the phosphorylation / dephosphoryla...
