Abstract

Background: HARE mediates systemic clearance of hyaluronan (HA), which turns over continuously in tissues.

Results: HARE uptake of 40–400-kDa, but not larger or smaller, HA stimulated NF-κB activation.

Conclusion: HA-HARE signal complexes activate NF-κB and gene transcription only with optimally sized HA.

Significance: HARE responsiveness to a narrow size range ofHAdegradation products may be a sensing system to detect tissue ECM stress.
