PREP and Cognitive impairment: Since we observed a negative correlation of the PHB2 protein levels and cognitive deficits (Figure 1D), we further characterized the protein levels of PHB2 in this animal model in combination with the prolyl oligopeptidase inhibitor IPR19 for 35 min (n = 6/group), which has been reported to ameliorate cognitive deficits in preclinical models related to SZ.
