Background

Dr. Scheherazade Sadegh-Nasseri is a professor of pathology at the Johns Hopkins University School of Medicine. Her research focuses on molecular mechanisms in antigen processing and presentation, T cell memory survival, T cell activation, and T cell tolerance.

Dr. Sadegh-Nasseri and her lab made the notable discovery that binding of peptides to MHC class II induces different conformations, a finding that has formed the basis for how peptide-MHC class II complexes are recognized and editted by the MHC class II accessory molecules. They have maintained a leading role in understanding mechanisms in peptide binding and the role of MHC class II accessory molecule, HLA-DM, in peptide exchange and editing. The team also reported the first cell free reductionist antigen processing system that identifies immunodominant epitopes from protein antigens for recognition by helper T cells.

Dr. Sadegh-Nasseri received her undergraduate degree from Pahlavi University in Iran and her M.Sc. in a joint program with Harvard University and Teheran University in Iran. She earned her Ph.D. from University of California at Los Angeles. She was a Cancer Research Institute Postdoctoral Scholar in Chemistry Department at Stanford University, and a Sr. Staff Fellow in Laboratory of Immunology of NIAID at NIH prior to her current department at the JHU.

Research Summary

Dr. Sadegh-Nasseri is interested in two general areas of T cell recognition. She investigates the biophysical and biochemical processes that control formation of complexes of antigenic fragments and the MHC Class II, and addresses cellular and molecular events related to T cell tolerance.

Lab

The long-term interests of Dr. Sadegh-Nasseri’s lab include understanding the molecular basis for the generation of ligands for presentation to CD4 T cells and investigating the parameters that control activation and inactivation of CD4 T cells.
