Abstract
Calstabin2, also named FK506 binding protein 12.6 (FKBP12.6), is a subunit of ryanodine receptor subtype 2 (RyR2) macromolecular complex, an intracellular calcium channel. Studies from our and other's lab have shown that hippocampal calstabin2 regulates spatial memory. Calstabin2 and RyR2 are widely distributed in the brain, including the amygdala, a key brain area involved in the regulation of emotion including fear. Little is known about the role of calstabin2 in fear memory. Here, we found that genetic deletion of calstabin2 impaired long-term memory in cued fear conditioning test. Knockdown calstabin2 in the lateral amygdala (LA) by viral vector also impaired long-term cued fear memory expression. Furthermore, calstabin2 knockout reduced long-term potentiation (LTP) at both cortical and thalamic inputs to the LA. In conclusion, our present data indicate that calstabin2 in the LA plays a crucial role in the regulating of emotional memory.

Abstract
Nociceptin/Orphanin FQ (N/OFQ) plays an important role in the regulation of spatial, fear and recognition memories. N/OFQ receptors are highly distributed in the perirhinal cortex, which is a key brain area involved in modulating novel object recognition (NOR) memory. However, the role of N/OFQ in NOR memory in the perirhinal cortex was still unknown. Moreover, the effects of N/OFQ on different stages of NOR memory were still unclear. In NOR task, we found that pre-training intracerebroventricular (icv) injection of N/OFQ (0.3 and 1 nmol) impaired long-term memory in a dose-dependent manner. However, icv infusion of N/OFQ immediately after training did not affect NOR memory consolidation even at a high dose of 3 nmol. Pre-test icv injection of N/OFQ (1 nmol) also did not influence NOR memory retrieval. These data indicate that N/OFQ negatively modulates long-term NOR memory during the acquisition phase. Furthermore, the amnesia effect of N/OFQ (1 nmol, icv) could be antagonist by pre-treatment with the selective N/OFQ receptor antagonist [Nphe1]N/OFQ(1-13)NH2 (10 nmol, icv), indicating pharmacological specificity. Then, we found that pre-training infusion of N/OFQ (0.1 and 0.3 nmol/side) into the bilateral perirhinal cortex impaired long-term NOR memory, suggesting the perirhinal cortex is a critical brain structure in mediating the amnesic effect of N/OFQ in NOR task. In conclusion, our data, for the first time, indicate that N/OFQ in the perirhinal cortex impairs NOR memory acquisition through the NOP receptors.
