Kim Lab

The research laboratory led by Jungsu Kim, PhD, is interested in understanding the molecular and cellular basis of neuronal and glial dysfunction in Alzheimer’s disease, other aging-associated neurodegenerative diseases, and normal brain aging.

Research in Kim lab is aimed at developing therapeutic strategies for Alzheimer’s disease by targeting microglial proteins implicated in neuroinflammation as well as brain lipid-regulating proteins, such as apolipoprotein E (ApoE), low density lipoprotein receptor (LDLR), and ATP-binding cassette transporter A1 (ABCA1). Kim lab is also interested in the role of epigenetics and non-coding RNAs in the pathogenesis of Alzheimer’s disease and other aging-associated neurodegenerative diseases. Emerging transcriptomics technologies recently revealed that many non-coding regions encode functional RNAs, such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs).

Using genetically modified animal models, human biospecimens, induced pluripotent stem cells (iPSC), emerging single-cell transcriptomics, single-cell proteomics, and systems biology approaches, Kim lab investigates the function of multiple microglial proteins, ApoE-binding proteins, and non-coding RNAs that may play critical roles in neurodegenerative diseases and brain aging.

Active Research

Research interests are centered on understanding the critical role of ApoE-associated proteins, microRNAs and long non-coding RNAs, leading aging-associated neurodegenerative disease. The lab has been interested in the function of microglia-mediated immune responses to Alzheimer’s disease progression. The research goal is to develop therapeutic targets to delay progression of Alzheimer’s disease by targeting brain lipid-regulating proteins such as apolipoprotein E, low density lipoprotein receptor and ATP-binding cassette transporter A1. The approaches used in the Kim lab include human and mouse genetics for candidate gene discovery, cell biology and animal modeling for functional study, small-scale drug screening and long-term in vivo drug efficacy testing.

PI: Jungsu Kim

Agency: NIH

Period: 9/1/2016 – 5/31/2019

The goal of this project is to study how microRNA-758-3p affects synaptic spine density and cognition by regulating CREB, ABCA1, ApoE lipidation and its implication to Alzheimer’s disease.

PI: Andrew Yoo (Washington University)

Agency: NIH

Period: 9/15/2017 – 6/30/2022

The major goal of this project is to use our established miRNA-TF- based conversion protocol to generate human cortical neurons, a neuronal type largely affected in AD, from fibroblast donors across the age spectrum, and obtain cortical neurons that represent donors’ ages as a cellular model of aging.
