Pharmacogenetics of antidepressant response and remission

Project Details

This collaboratively funded project involves collaborations with national and international investigators working in the filed of antidepressant pharmacogenetics. Since 2013, we have been leading and/or supervising analyses aimed at identifying genetic markers for antidepressant mediated symptom response and remission. We currently co-lead analyses related to the pharmacogenetics of escitalopram with Prof Tianmei Si (Director, Department of Clinical Pharmacology, Peking University) as well as analyses to identify pharmacogenetic markers of desvenlafaxine and venlafaxine with A/Prof Ajeet Singh at Deakin University. Over the next two years, we will specifically be focusing on analyses of genes and variants with functional effects on the integrity of the blood-brain barrier such as ABCB1, which encodes p-glycoprotien, as we have previously shown an association between genetic variation in this gene and antidepressant response.
