Research Abstract

Infectious diseases are still threats to humans, and the mechanism by which pathogens infect their hosts is not fully understood yet. The present study tested the hypothesis that molecules carrying mutations with unknown function interact with pathogens. In the process of comprehensive search for interaction between pathogens and host molecules, it was found that an orphan activating receptor specifically recognized some host molecule degraded by bacteria. These results suggest that host immune system has a novel strategy to sense bacterial invasion via an activating receptor.
