Congratulations Hervé! The Agaisse laboratory studies the bacterial pathogen Shigella flexneri, which causes approximately 270 million cases of bacillary dysentery (blood in stool) worldwide every year. We have recently developed an infant rabbit model of bacillary dysentery that recapitulates all the symptoms observed in infected individuals. We intend to use the Pinn Scholar award to investigate how Shigella flexneri invades the colonic lamina propria and interacts with immune cells in vivo.
