报告人简介:

Prof. Allan J. Zajac obtained his B.Sc in Microbiology &Virology from University of Warwick , Coventry, UK in 1991 and Ph.D. in Microbiology & Immunology from University of North Carolina, Chapel Hill, NC. in 1996. He completed his postdoctoral training on Viral Immunology at Emory University, Atlanta, GA from 1996 to 1999. He has been a faculty and promoted to tenured associate professor in the Department of Microbiology at the University of Alabama at Birmingham since 2007. His research program is centered on the understanding of robust and highly effective immune responses induced by viral infections and vaccinations and immune evasion resulting in persistent viral infections. 

Prof. Zajac has made many important contributions to understanding the importance of CD4 and CD8 T cells in the control of viral infections. He has discovered that the CD4 T cell-derived cytokine, IL-21, is essential for sustaining cell-mediated immunity in chronically infected hosts.  More recently, his group has demonstrated how adhesion molecule interactions influence the balance of effector and memory T cells and regulate the deletion of virus-specific CD8 T cells during chronic viral infections. His research interests mainly focus on the functional complexity of CD8 T cell responses, particularly on the questions of how the formation of discrete cytokine- producing subsets is controlled and how they contribute to the success or failure of anti-viral immunity.
