1 Losartan treatment decreased AT1R binding in the ventral subiculum of sham and ovariectomized rats by 41.6%, and 46% in the piriform cortex of the sham rats, but tended to increase AT1R binding in the piriform cortex and cingulate cortex 77% and 107%, respectively, in the ovariectomized rats. Losartan angiotensin II receptor, type 1a Rattus norvegicus

3 These results suggest that losartan-induced changes in brain AT1R expression may contribute to the reduced anxiety-like behavior and memory impairments seen in ovariectomized rats, but replication of these observations will be needed to determine the extent to which brain AT1R changes mediate the adverse behavioral effects of ovariectomy.
