 This research paper examined the differences between two types of oral-like complainers, OLP, which are characterized by distinctive immunological features. By analyzing the gene expression profiles of OLP patients, the authors identified two distinct clusters of OLP patients, one of which had more severe symptoms than the other. This suggests that there may be two distinct forms of OLP, each with its own unique immunological profile. This article was authored by Jean Hao Zhong, Gao Ge Peng, Hao Kai, and others.
