RESEARCH INTERESTS

Research Description:

Dr. Juang’s research uses Drosophila genetics combined with mouse and cell line models to explore molecular mechanisms and potential therapies for Alzheimer’s disease (AD). His current research interests focus on two areas: one in inter-organ crosstalk in the development of Alzheimer’s disease and the other in AD and metabolic dysfunction. For inter-organ crosstalk, they investigate how signaling cues initiated by adverse environmental or cellular factors in one organ play a role in impacting the brain to cause AD. For instance, they demonstrated that the gut-brain axis is a fundamental factor contributing to the development of AD. For AD and metabolic dysfunction, they discovered that beta amyloid plays an important role in modulating metabolic pathways in peripheral organs, by which the brain’s metabolism and immune function are intimately connected with peripheral organs during the development of AD. They attempt to explore novel therapeutics for AD based on the mechanistic findings.

HIGHLIGHTS OF RECENT RESEARCH

Immunological cross talks between gut and other organs in the body

Immunological cross-talk between organs helps maintain the homeostasis of immune responses, thereby, enhancing immune protection of the host. For instance, when intestines are infected with harmful microbes, it not only would hamper intestinal health, but also trigger immunological reactions in other organs. Yet, the molecular mechanisms underlying the immunological communication remain unclear. Drosophila shares a similar innate immune system with humans and is an excellent genetic model system for studying inter-organ communication. Dr. Juang’s lab found that after the gut experiences bacterial stress, the increase of ROS in gut initiates an innate immune response in a remote organ fat body (analogous to human liver). This communication pathway is done via nitric oxide and hemocytes and another unknown messenger in carrying the ROS signal in the gut to the fat body, which then activates the Relish/NF-KB transcription factors and induces an antimicrobial peptide response in the fat body. The results of this study have been published in Cell Host & Microbe (2012), and is one of the stories that received a preview. This study’s importance is that it reveals that when an organism experience microbial threats in the gut, how would it signal other organs to induce immune response and protect it from harm, letting us better understand how to prevent immune-related diseases and further to therapeutic drug development.
