￭ 연구 소개 (Research in brief)
분자 뇌영상 연구실에서는 radioligand를 이용한 고해상도 분자 PET 영상을 기반으로 뇌신경수용체, 뇌신경전달체 등 다양한 신경전달물질 관련 대뇌 단백질의 농도를 정량화하고 신경전달물질의 변화량을 정량화함으로써 정신질환의 병태생리를 밝히는 연구를 수행하고 있다. 이를 통하여 주요 정신질환 병태생리 연구에 핵심적인 대리 표지자를 발굴하고 나아가 새로운 치료법의 개발을 위한 표적을 발굴하는 것을 목적으로 하고 있다. 또한, multi-tracer, multi-modality 기법을 통하여 정신질환의 병태생리 연구에 새로운 방법론을 제시하고자 한다.
My Lab (Molecular Brain Imaging Lab) is conducting research to explore the pathogenesis of major psychiatric disorders using high-resolution molecular PET imaging with radioligands, which enables the quantification of the concentrations of various neuroreceptors/transporters and neurotransmitter-related proteins in human brain. The purpose of my research is to find surrogate markers that are keys to understand the pathogenesis of major mental illnesses and to discover novel targets for the development of new treatments. In addition, we are conducting multi-tracer and multi-modality imaging techniques, which can provide new methodologies for research on the pathophysiology of mental illness.
