Aberrant IGF1-PI3K/AKT/MTOR signaling pathway regulates the local immunity of oral lichen planus

摘要

Objectives: Oral lichen planus (OLP) is a T cell-mediated immune-related chronic disease, featured by accumulation of T cells and apoptosis of keratinocytes. Insulin-like growth factors 1 (IGF1) signaling, in combination with its downstream PI3K/AKT/MTOR cascade, plays pivotal roles in the regulation of inflammation and immune response. Meanwhile, TRB3 acts as a connective protein in the pathway. This study investigated the possible function of IGF1-PI3K/AKT/MTOR pathway in the local immunity of OLP.
