IFNG and oral lichen planus: One study [21] identified that Golli-MBP (human Golli-myelin basic protein) was suspected to play a role in the etiology of autoimmune diseases and the gene expression ratio of IFN-γ/IL-4, and increased Golli-MBP was related to a lower ratio of IFN-γ/IL-4 in OLP patients.
