It's rare in this feature to highlight a researcher's work twice in the same year, because it is rare for a researcher to achieve what Gabriel Nuñez's team at the University of Michigan, Ann Arbor, has accomplished. Besides generating at least three Hot Papers on NOD1 and NOD2 in a matter of a few months,1-3 Nuñez helped create the discipline of intracellular pathogen recognition, and influenced the work of scientists in fields as diverse as genetics, innate and mucosal immunity, gastroenterology, and...
