Beyond barrier immunity: IL-17 safeguards the renal epithelium.
IL-17 activates a tPA-LRP1 pathway that protects the renal epithelium during systemic candidiasis, highlighting a novel organ-preserving immune mechanism.
- Why it matters: Understanding how immune responses prevent tissue damage is crucial for improving treatments for systemic infections. This work addresses the gap in knowledge about IL-17’s role beyond mucosal immunity, specifically in safeguarding kidney tissue.
- What they did: Choi et al. investigated the downstream effects of IL-17 signaling and identified the tPA-LRP1 axis as a key mediator in renal epithelium protection during fungal infection.
- The result: The findings demonstrate that IL-17 promotes organ integrity through this pathway, offering potential targets for therapies to prevent tissue damage in systemic fungal infections.
