抄録
The senescence accelerated mouse(SAM)is known as a murine model of aging.SAM consists of senescence accelerated−prone mouse(SAMP)and senescence accelerated−resistant mouse(SAMR).Previous studies reported that SAMP10 exhibits age−related learning impairments and behavioral depression in a tail suspension test after 7 months.We investigated the changes in emotional behavior in a forced swimming test and in receptors for dopamine and 5−hydroxytryptamine(5−HT)in SAMP10.SAMP10 at 8 months showed an increase of immobility in the test compared with SAMR1.Treatment with desipramine(25 mg/kg, i.p., 3 days)in SAMP10 caused a decrease in immobility.In the cortex from SAMP10, [3H]quinpirole binding to D2/D3 dopamine receptors increased significantly compared with control SAMR1.In the hippocampus from SAMP10, [3H]8−hydroxy DPAT binding to 5−HT1A receptor increased.In midbrains from SAMP10, bindings of [3H]quinpirole and [3H]8−hydroxy DPAT increased.[3H]SCH23390 binding to D1/D5 receptors and [3H]ketanserin binding to 5−HT2 receptor in brain regions examined in SAMP10 were similar to those in SAMR1.The present findings represent the first neurochemical evidence of an increase of D2/D3 and 5−HT1A receptors in SAMP10.SAMP10 may be a useful model of aging associated depressive behavior.
