My group is interested in dissecting innate immune signaling triggered by pattern-recognition receptors (PRRs), particularly Toll-like receptors (TLRs) and the nucleotide-binding domain, leucine-rich repeat–containing (NBD-LRR) proteins (NLRs). The innate immune response constitutes the first line of defense against pathogens and tissue-associated “danger” signals during infection, inflammation or other types of cell stress. Signaling by these receptors initiates key inflammatory responses driving tissue damage. Dysregulated TLR or NLR signaling contributes to the underlying mechanism in many chronic diseases, such as neurodegenerative disorder, metabolic syndrome, autoimmune disease and cancer.
Our goal is to identify and characterize novel innate immune signaling nodes and uncover novel regulatory mechanisms, and eventually develop pathway selective modulators to treat inflammation-associated diseases by restoring tissue homeostasis. We are particularly interested in the interface of innate and adaptive immunity and the functional consequences of innate immune regulators in neurodegenerative diseases. We utilize a wide array of discovery technologies, including chemical genetics, functional genomics and various in vitro and in vivo models. We work closely with discovery platforms and many other disease areas at NIBR, including Autoimmunity, Transplantation & Inflammation, Cardiovascular & Metabolic Disease, and Immune Oncology.
