How it works

Stress causes the body to release too much cortisol, which disrupts immune control in the mouth. This allows immune cells to overproduce IL-6, which attacks the mouth lining and creates sores and redness. The more stress and inflammation present, the worse the sores become.

Most probable mechanism

In Simple Terms

When a person is under stress, the brain signals the body to release a hormone called cortisol. High levels of cortisol interfere with the normal control of immune cells in the mouth, causing them to become overactive and produce too much of another inflammatory signal called IL-6. This excess IL-6 triggers more immune cells to attack the lining of the mouth, leading to sores, redness, and ulcers that get worse as cortisol and IL-6 levels rise.

Causal chain
1

Psychological stress stimulates the hypothalamus to release corticotropin-releasing hormone

Indirect evidence only
which leads to
2

Corticotropin-releasing hormone triggers the pituitary gland to release ACTH, which stimulates the adrenal glands to produce and secrete cortisol

Verified by multiple studies
which leads to
3

Elevated cortisol impairs the function of regulatory T-cells and promotes a shift toward Th1 and Th17 immune responses

Supported by evidence
which leads to
4

Dysregulated T-cells and activated dendritic cells in the oral mucosa increase production of interleukin-6

Verified by multiple studies
which leads to
5

Interleukin-6 drives activation of T-cells, proliferation of B-cells, and recruitment of inflammatory cells to the oral mucosa

Verified by multiple studies
which leads to
6

Sustained interleukin-6 signaling causes epithelial damage, tissue destruction, and clinical manifestations including reticulation, erythema, and ulceration

People with oral lichen planus have higher levels of interleukin-6 and cortisol in their saliva than people without the condition, and higher levels of these biomarkers are linked to more severe symptoms.

People with oral lichen planus have different levels of interleukin-6 and cortisol in their saliva compared to healthy people, and these differences can be used to identify the condition without invasive tests.

People with oral lichen planus have higher levels of interleukin-6 in their saliva than people without the condition, and these higher levels are directly related to how severe their oral tissue damage is.
