Highlights

Dr. Chu，who has a research background in integrating innate immunity, neurodegenerative diseases and chemical biology, has published 9 high-level papers in Nature, Cell Chemical Biology and other journals as an independent first author. Dr. Chu graduated from Tsinghua University in 2015 with a Ph.D. degree under the tutelage of Prof. Yanmei Li to study the aggregation mechanism and inhibitor development of proteins related to neurodegenerative diseases. She first applied the 'PROTAC' strategy to the degradation of Alzheimer's disease-related Tau protein, which was published in a cover article on Cell Chemical Biology (2016), the invention was awarded a national patent, and Dr. Chu won the "Young Peptide Scientist Award" at the 14th China International Peptide Conference. In 2017, she joined Dr. Nan Yan’s lab in the department of Immunology in University of Texas Southwestern Medical Center for postdoctoral research. She focused on the research of innate immunity, autoimmune diseases, and neuroimmunity. She was particularly interested in the study of cGAS-STING signaling pathway and neuroimmunity. She found that STING signal mediates the neuropathological process of the rare neurodegenerative Niemann Pick disease, type C. This study has discovered novel STING regulators that expand immunologists' understanding of STING biology and constitute a major advance in this field. This study also provided a new understanding of Niemann Pick disease from immune perspective, leading to a new therapeutic target and strategy. This work was published in Nature (2021) as an independent first author. This paper was reviewed by Nature Cell Biology, and featured by BIOART, Bioon, Science Network and other media. Dr. Chu will use multidisciplinary research methods to devote herself to the innate immune signaling pathway; The role and mechanism of innate immunity in neurodegenerative diseases and autoimmune diseases.
