Transmembrane proteases in focus: diversity and redundancy?

abstract：:The IV meeting of the European Mucosal Immunology Group, held October 8-10, 2004, in Lyon, gathered fundamental and clinical research scientists to discuss the most recent updates on basic and clinical aspects of mucosal immunology. The meeting was focused on innate and acquired immune mechanisms underlying handling a...
