Abstract

Objective

Oral lichen planus (OLP) is a T cell-mediated inflammatory disease with uncertain etiology. Exosomes are cell-derived vesicles containing biological cargo, being associated with the development of multiple inflammatory diseases. The present study aims to investigate the role of T cell-derived exosomes in the pathogenesis of OLP.

Methods

Exosomal marker CD63 was detected in OLP lesions by immunohistochemistry. Twenty-three cytokines in T cell-derived exosomes were assessed using luminex xMAP-based assay. After co-incubating with exosomes, the apoptosis of keratinocytes and the proliferation of Jurkat cells were assessed via flow cytometry and cell counting kit-8 assay, respectively.

Results

CD63 was highly expressed in the lymphocyte infiltrated areas of OLP lesions. OLP T cell-derived exosomes contained upregulated interleukin-7, -10, -12, -17 and downregulated interleukin-1β, -5, and interferon-γ. Both exosomes from OLP patients and controls induced the apoptosis of keratinocytes and altered their morphology. Moreover, healthy control–derived exosomes markedly inhibited the proliferation of Jurkat cells, whereas OLP-derived exosomes exhibited no inhibitory effect.

Conclusions

OLP T cell-derived exosomes have an aberrant cytokine profile and could trigger the apoptosis of keratinocytes in vitro, which may be involved in the pathogenesis of OLP.
