Summary

Scientists checked saliva from people with a chronic mouth condition and healthy people to see if two chemicals — one from inflammation and one from stress — were higher in those with worse symptoms.

Proposed Mechanism
Stress-induced HPA axis activation exacerbates OLP via cortisol-mediated immune dysregulation
Suggested
Local mucosal inflammation in OLP driven by IL-6-mediated immune activation
