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 brain lipid-regulating proteins, such as apolipoprotein E (ApoE), low density lipoprotein receptor (LDLR), and ATP-binding cassette transporter A1 (ABCA1). The 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 actually encode functional RNAs, such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs). Using cell culture, animal models, and systems biology approaches, the Kim lab investigates non-coding RNAs that may play critical roles in neurodegenerative diseases, brain aging, and cardiovascular diseases.

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.
  • The Role of Aging-Associated MicroRNAs in Alzheimer’s Disease

    PI: Jungsu Kim

    Agency: NIH

    Period: 9/1/2016 – 5/31/2021

    The goals of this project are to determine the role of aging-associated microRNA cluster in brain insulin signaling during aging and memory loss using animal models.

  • Role of MicroRNA-33 in Alzheimer’s Disease

    PI: Jungsu Kim

    Agency: NIH

    Period: 9/1/2016 – 4/30/2021

    The goals of this project are to study how miR-33 regulates neuroinflammation, ABCA1, and lipid metabolism and to determine the therapeutic effect of anti-miR-33 ASO using animal models.

  • Role of LDLR in Regulating Metabolism of Apolipoprotein E and Amyloid-Beta

    PI: Jungsu Kim

    Agency: NIH

    Period: 9/15/2016 – 4/30/2021

  • MicroRNA-758-3p in Cognition and Alzheimer's Disease

    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.

  • Modeling Neuronal Aging and Alzheimers Disease in Human Neurons Directly Converted from Fibroblasts

    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.
