Hippocampal group III mGlu receptor mRNA levels are not altered in specific mouse models of stress, depression and antidepressant action

► Chronic immobilisation stress did not alter hippocampal mGlu receptor levels. ► Chronic lithium and/or chronic stress did not alter hippocampal mGlu receptor levels. ► No difference in hippocampal mGlu receptor levels in a genetic model of helplessness.
