    Abstract:
    Oral lichen planus (OLP) is suggested to be a T cell-mediated chronic inflammatory oral mucosal disease. Gene expressed in the oligodendrocyte lineage-myelin basic proteins (Golli-MBP) and stromal interaction molecule 1 (STIM1) are important in the activation and function of T lymphocytes. This study aimed to analyze and compare the expression of Golli-MBP and STIM1 between OLP patients and healthy controls and to analyze the level of intracellular Ca(2+), which is involved in lymphocyte activation. The Ca(2+) fluorescent probe, Fluo-3/AM, was used to test the level of intracellular Ca(2+) in patients with OLP and healthy controls peripheral blood lymphocytes. Golli-MBP and STIM1 mRNA and protein levels were analyzed using quantitative real-time PCR and Western blot, respectively. Following lymphocyte activation, the intracellular Ca(2+) in OLP patients was markedly lower than that in the control group (P < 0.001). In OLP patients, the expression of Golli-MBP mRNA and protein was significantly upregulated compared to those of the control group (P < 0.001). Similarly, OLP patients showed markedly upregulated levels of STIM1 mRNA expression (P < 0.01) and protein compared to healthy controls. The intracellular Ca(2+) of OLP patients was markedly lower than that of healthy controls. This evidence may indicate that Ca(2+) signaling pathways in OLP patients are abnormal. The overexpression of Golli-MBP and STIM1 may play a role in the pathogenesis of OLP.
