Control of inflammation is critical for therapy of infectious diseases. Pathogen-associated and/or danger-associated molecular patterns (PAMPs and DAMPs, respectively) are the two major inducers of inflammation. Because the CD24-Siglec G/10 interactions selectively repress inflammatory response to DAMPs, microbial disruption of the negative regulation would provide a general mechanism to exacerbate inflammation. Here we show that the sialic acid-based pattern recognitions of CD24 by Siglec G/10 are targeted by sialidases in polybacterial sepsis. Sialidase inhibitors protect mice against sepsis by a CD24-Siglecg-dependent mechanism, whereas a targeted mutation of either CD24 or Siglecg exacerbates sepsis. Bacterial sialidase and host CD24 and Siglecg genes interact to determine pathogen virulence. Our data demonstrate a critical role for disrupting sialic acid-based pattern recognitions in microbial virulence and suggest a therapeutic approach to dampen harmful inflammatory response during infection.
