AIM Brain-derived neurotrophic factor (BDNF) plays an important role in learning and memory in multiple brain areas. In the present study, we investigated the roles of BDNF in aversive memories associated with conditioned drug withdrawal in acute morphine-dependent rats. METHODS Conditioned place aversion (CPA) was induced in male SD rats exposed to a(More)
BACKGROUND AND PURPOSE β-Arrestins function as signal transducers linking GPCRs to ERK1/2 signalling either by scaffolding members of ERK1/2s cascades or by transactivating receptor tyrosine kinases through Src-mediated release of transactivating factor. Recruitment of β-arrestins to the activated GPCRs is required for ERK1/2 activation. Our previous(More)
Extinction of aversive memories has been a major concern in neuropsychiatric disorders, such as anxiety disorders and drug addiction. However, the mechanisms underlying extinction of aversive memories are not fully understood. Here, we report that extinction of conditioned place aversion (CPA) to naloxone-precipitated opiate withdrawal in male rats(More)
Repeated exposure to methamphetamine (METH) can cause severe neurotoxicity to the cortical neurons. In the present study, we investigated the effect of METH on cognitive function deficits, and determined the neuroprotective effects of memantine (MEM) on memory impairment induced by METH. The protein levels of Bcl-2 and cleaved caspase-3 in prefrontal cortex(More)
Abuse of methamphetamine (METH), a powerful addictive amphetamine-type stimulants (ATS), is becoming a global public health problem. The gamma-aminobutyric acid (GABA)ergic system plays a critical role in METH use disorders. By using rat METH conditioned place preference (CPP) model, we previously demonstrated that METH-associated rewarding memory formation(More)
