abstractText | Tolerance is an important component of opiate addiction, but the molecular basis for this phenomenon remains obscure. Here, we report that mice lacking neurotrophin-4 (NT4) display substantially reduced tolerance to morphine compared to wild-type. However, there were no deficits in sensitization and withdrawal, other behaviors relevant to drug addiction. Since NT4 knockout mice also show abnormalities in long-term but not short-term memory, our findings suggest common molecular pathways for some of the enduring changes of drug addiction and memory consolidation. |
