Bacterial infections remain an important clinical challenge despite our extensive arsenal of antibiotics. This is exemplified by lengthy treatments of chronic infections, high mortality due to excessive inflammation, and an alarming increase in antibiotic resistance. One attractive strategy for improved treatments for challenging infections is to enhance the host anti-microbial defence. We and others have associated the WNT signalling pathway with bacterial infections in patients and model systems, implicating novel immune-related functions for this well-known developmental signalling pathway. However, the nature of its contribution to the host response to infection remains to be clearly defined. This presentation explores infection-associated WNT responses in patients and model systems, and delineates functions of WNT signalling in tailoring host responses to acute bacterial infection.
