2024 Kuan-Teh Jeang Memorial Lecture: The broad impact of innate immune receptors in viral infection, cancer and autoimmunity
Jenny Pan-Yun Ting is a Taiwanese-American immunologist and microbiologist at University of North Carolina. She is a highly cited researcher who studies the role of NLR genes in regulating inflammation and how nanoparticles and microparticles can be used as vaccine adjuvants. In memory of Kuan-Teh Jeang, the lecture will discuss the roles of multiple innate immune receptors in viral infection in mouse models and patients. The seminar will also describe the unexpected intrinsic roles of these receptors in adaptive T and B lymphocytes. The latter adects both cancer and autoimmunity, with implications for immunotherapeutics.I...

How does the Plasma Membrane Participate in Receptor-Mediated Cell Signaling?
Cells are poised to respond to their physical environment and must distinguish specific stimuli from biological noise. Specific response mechanisms depend on collective molecular interactions that are regulated in time and space by the plasma membrane and its connections with the cytoskeleton and intracellular structures. Molecular stimuli engage their specific receptors to initiate a transmembrane signal, and the surrounding system efficiently rearranges to amplify this nanoscale interaction to microscale assemblies, yielding a cellular response that often reaches to longer length scales within the organism. A striking ex...

Designing Nanoparticles to Probe and Cross Biological Barriers to Immunotherapy
The Mucosal Associated Immune System Engineering and Lymphatics (MAISEL) Lab ’ s research integrates nanotechnology, materials science, and tissue engineering with physiology, medicine, and immunology to probe lymphatics and extracellular barriers via novel ex vivo and in vitro models and nanoparticles. We are particularly focused on studying mucosal barriers to the therapeutic path from the mucosal lumen to the downstream lymph nodes and integrating the newly created knowledge to design immune modulatory therapeutic interventions. We have made significant progress in understanding how nanoparticle material properties li...
