My laboratory is interested in understanding mechanisms of neuronal connectivity and plasticity, how these processes are modulated by environmental and genetic factors, and how they are altered in human diseases and under drug conditions. We will continue to employ a combination of behavioral, physiological, pharmacological, and genomic approaches for the following projects.
Discovering fast-acting antidepressants. Depression is a prevalent, heterogeneous mood disorder, affecting ~16% of population worldwide. Currently available antidepressant agents have significant therapeutic limitations including slow on-sets, treatment resistance, and a high incidence of relapse, highlighting the critical need to develop new therapies. We seek to evaluate potential pharmacological interventions targeting glutamatergic transmission mechanisms, such as ketamine. The downside of ketamine treatment is its abuse potential and the dissociative and psychotomimetic side effects. We are currently testing candidate drugs targeting NMDA receptors with the goal of discovering fast-acting and long-lasting antidepressants.
Gut microbiota in mood regulation. Emerging evidence supports a bidirectional communication axis between the brain, the gastrointestinal tract, and the microbiota colonizing the gut (commonly referred to as the “brain-gut-microbiota axis”). Using shotgun sequencing and metagenomic analysis, we investigate the role played by the gut microbiome in mood (dys) regulation resulted from chronic stress or the affective component of chronic pain. Results on how gut microbiome help regulate the host stress response may shed light on potential targeted therapies at the microbiome for disease conditions.
