Research interests

The focus of Neuropharmacology lab is to understand the cellular and molecular of several neurological and psychiatric disorders, such as drug addiction, depression, schizophrenia, pain and Parkinson’s disease. The efforts by lab participants during previous years had generated many interesting research findings and now we are continuously working on the following research topics:

 (1)Drug addiction acquisition, extinction and relapse: via behavioral sensitization and conditioned place    preference (CPP) as addiction model conducted on rodents, we intend to explore the neural signals from prefrontal glutamate that project to the midbrain dopamine cell body in the ventral tegmental area (VTA) and discover how stress hormone CRF reinstates the addiction memory and its underlying cellular mechanism.

(2)Brain neuropeptide FF (NPFF)- NPFFR system: via research on home-made NPFFR2 Tg mice, we already found this Tg mice exhibit hypralgesia and depression/anxiety and the outcome of NPFFR2 over-expression on HPA axis, ascending nociceptive pathway, CGRP release and hippocampal neurogenesis. We are now producing NPFFR2 KO mice and will characterize their behavioral and biochemical phenotypes in order to understand the physiological role of brain NPFF-NPFFR system.

(3)Parkinson’s disease and L-dopa-induced dyskinesia (LID): previously, we identified that dopamine D3 receptor stimulation would evoke adult stem/progenitor cell proliferation in the SVZ area and further found systemic D3R agonist treatment could restore the motor dysfunction due to MPTP lesion in the striatum. We are now explore the cellular mechanism of LID via median forebrain bundle 6-OHDA-lesioned mice model, as well as Metabolomic profiling of PD and LID patients.

(4)Psychosis and cognition: via chronic ketamine administration, we intend to explore the cellular mechanism underlying the ketamine addiction and psychosis, focusing on the nucleus accumbens. In addition, via dopamine transporter (DAT) KD mice, we study the role of dopamine D3R on cognitive ability (novel object recognition test) focusing on the neurochemistry of prefrontal cortex.

The expertise in our lab is behavioral manipulation in rodents and in vivo and in vitro biochemical analyses. Experimental techniques routinely performed in our laboratory include western blot, IHC/ICC, brain microdialysis-HPLC, stereotaxic surgery and cannulation, qPCR, cell culture and transfection, behavioral observation (water maze, forced swim test, open-field activity, tail suspension test, NORT, pre-pulse inhibition, CPP, startling, elevated plus maze, von Frey test, etc.). Recently, we established the optogenetic technique and will conduct on GluT-, Gad2-, Pvalb-cre mice for targeting designated neural circuitry. Upon identifying the altered target(s) in in vivo system, a cell culture system would also be adopted for mechanistic study. It is expected that through comprehensive approaches, i.e. from cellular to systemic, we would be able to understand the causes of particular neural disorder and will eventually benefit the translational research.
