项目摘要
Abstract
Opiate addiction is a huge public health threat in the United States currently. There is a real need for new
treatments that reduce relapse rates, and a major relapse trigger is exposure to conditioned drug cues. The
conditioned response to seek drug is intimately tied to the memory retrieved by these reminder cues. However,
repeated exposure to these cues in the absence of reward can lead to a diminished conditioned response to
seek drug, through a process known as extinction. Extinction is thought to establish an opposing inhibitory
memory that suppresses the conditioned response, and has been shown to recruit portions of the prefrontal
cortex. In particular, the infralimbic (IL) subregion in rodents exerts this inhibitory control over downstream
effectors that would otherwise drive the conditioned response. This is true for a number of conditioned
behaviors, including conditioned cocaine seeking, food seeking, and fear. Preliminary data suggest that the
inhibitory function of this region is masked, but not lost, after heroin self-administration. This may be due to a
primary site of action of heroin at mu opioid receptors (MORs) in IL, as activation of IL-MORs elicits feeding
and a general hyper-appetitive state (Baldo 2016). Preliminary data suggest that IL-MORs also regulate the
motivation to seek heroin, and is consistent with a theory separate appetitive driver and limiter functions exist
within the IL cortex. These opposing functions may be encoded by distinct neuronal ensembles within IL with
distinct downstream targets. Two major efferent targets of IL that are known to regulate both food and drug
seeking are the lateral hypothalamus (LH) and the nucleus accumbens shell (NAshell). We propose that IL
neuronal ensembles projecting to the LH drive heroin seeking, whereas those projecting to the NAshell inhibit
heroin seeking. Indeed, preliminary data show that chemogenetic activation of the IL to NAshell pathway
reduces cue-induced reinstatement of heroin seeking, similar to our reported effects in cocaine-seeking
animals (Augur et al. 2016). We will use a novel TRAP-DREADD system to tag and reactivate different
functional neuronal ensembles in IL that drive versus inhibit heroin seeking, and we will identify their
downstream efferent targets by retrograde tracing. We will also use pathway-specific chemogenetics to
activate these different IL efferent pathways and establish their functional role in cue-induced heroin relapse.
Finally, we will use a novel trans-synaptic "trans-DREADD" strategy to examine the second-order circuits
controlling heroin seeking. These experiments will determine the specific functional neural circuitry of IL and its
downstream effectors, and establish their role in driving vs limiting heroin seeking. Furthermore, this work will
provide new insight into the specific neuroanatomy controlling heroin seeking and the extent to which these
limiter circuits can be exploited to reduce relapse.

鸦片成瘾是目前在美国的巨大公共卫生威胁。真正需要新的

最后,我们将使用一种新颖的反式突触“跨二读”策略来检查二阶电路

可以探索限制电路以减少复发。
