Research Interests
Persistent pain is a part of many common human clinical conditions, yet the current ability to diagnose and manage these conditions is inadequate. Pain perception is one of the most complicated measurable traits, as it is composed of an aggregate of several other measurable phenotypes associated with peripheral and central nervous system dynamics, stress responsiveness, and inflammatory state. It is generally accepted that complex traits, like pain perception, result from the interplay between environmental exposures and multiple genetic variants. The Diatchenko lab investigates the psychological, molecular, cellular, and genetic pathways that mediate both acute and persistent pain states. The primary goal is to identify the critical elements of human genetic variability contributing to pain sensitivity and pathophysiological pain states that will enable individualized treatments and therapies. Other related research endeavors include molecular hierarchy of functional SNPs (single-nucleotide polymorphisms) and SNP-depend regulation of gene expression underlying molecular pain signaling. Answering these questions requires collaboration with experts in both clinical and basic biological sciences. Such collaborative activities allow the Diatchenko group to take basic genetic findings all the way from human association studies, through molecular and cellular mechanisms, to animal models, and ultimately to human clinical trials.
