Parameter-screened LED therapy targets STAT3/IL-6 axis to attenuate tendinopathy via dual modulation of inflammation and ECM remodeling

Key Points

The research aims to investigate how LED therapy can restore tendon health by targeting the STAT3/IL-6 signaling pathway.
Examined the effects of IL-1β on tendon homeostasis.
Administered LED therapy at 625 nm with a dosage of 52.8 J/cm².
Analyzed changes in STAT3 activity and IL-6 expression after treatment.
LED therapy countered the inflammatory effects of IL-1β on tendon tissue.
Restoration of STAT3 activity was observed post-LED treatment.
IL-6 expression levels were significantly suppressed by LED therapy.

Abstract

IL-1β disrupts tendon homeostasis by driving inflammation and ECM degradation. LED therapy at 625 nm/52.8 J/cm2 mitigates these effects, potentially by restoring STAT3 activity within the IL-6/STAT3 axis, thereby suppressing IL-6 expression.This provides a mechanistic foundation for refining LED-based tendinopathy treatments.
