On Friday the 21st of Feb at 11 am (salle Marcel Dorée, CNRS campus), Prof. Jack Stapleton, from Iowa university, will be presenting some of his recent work, entitled:
«  A flavivirus genome-derived noncoding RNA regulates T cell function and restricts virus replication ».
 
Jack Stapleton’s minibio: Jack is a Professor of Internal Medicine, Infectious Diseases and Microbiology at the University of Iowa.  Over the last 3 decades, his laboratory has focused on positive strand RNA viruses (HIV, HCV, GBV-C/HPgv) and how members of the Flaviviridae interact with HIV and immune function.  Most recently, the lab studies how HCV and yellow fever virus genomic RNA is processed into short, noncoding RNAs that regulate T cell function and enhance viral replication.  He also has conducted numerous translational studies on how human pegivirus (GBV-C) prolongs survival in HIV infected people, and characterized mechanisms involved in this beneficial co-infection.

Jack will be spending the next few months on a sabbatical in my lab. If you wish to meet with him, just let us know!
