Meet Nilofer Qureshi
Biography

Dr. Qureshi is a professor of biomedical science, and director of the Shock/Trauma Research Center. Trained at the University of Wisconsin/VA Medical Center, Dr. Qureshi focuses on basic/clinical research of novel treatments for sepsis based on the proteasomes. She is an internationally recognized expert in chemistry of toxins, antagonists for toxins, mechanisms responsible for septic shock and proteasomes.  Her research has been funded continually since 1994 by the National Institutes of Health as principal investigator. Her research program has fundamental relevance to basic science and translational research as evidenced by more than 160 peer-reviewed publications in scientific journals, and book chapters.

Dr. Qureshi has more than 35 years of experience in the fields of endotoxins and inflammation research, drug development, and translational research.  She has served as reviewer for professional scientific journals, and serves on the editorial board of the Shock journal and several other journals.  She has served as a reviewer for several national and international funding agencies including the National Institutes of Health and German agencies.

Research Focus

To develop novel therapeutic approaches to treat septic shock and inflammation.

Research Summary

Dr. Qureshi was the first to establish the complete structure of the lipid A moiety of the enterobacterial lipopolysaccharide (LPS), developed monophosphoryl lipid A as an effective adjuvant; and Rhodobacter sphaeroides diphosphoryl lipid A as a powerful LPS antagonist in both in vitro and in vivo systems. Her recent research centers on the biology of LPS, especially, with regards to its effect on the ubiquitin-proteasome pathway in macrophages/monocytes and septic shock. Dr. Qureshi pioneered the concept that LPS-induced cytokines are dependent on the composition of proteasome’s subunits present in the cells. The proteasomes controls multiple signaling pathways triggered by LPS. All cells contain different subunits of proteasomes. The conclusion from these studies is that the proteasome is a central regulator of cellular function and inflammation/tolerance and is involved in several diseases such as septic shock, diabetes and cardiovascular problems, cancer and asthma. Presently, she is working on a novel therapeutic approach for septic shock based upon proteasome inhibitors / activators and antibiotics. Several important biomarkers present in blood of septic shock patients have been identified. Several natural compounds have now been developed for modulating the proteasome activities.
