In vitro plasma stimulation test. PBMCs from healthy controls and OLP patients were stimulated with OLP plasma or normal plasma for 3 days. (A) Gating strategy identifying ILC1s and ILC2s. The ILC1 and ILC2 proportions in total ILCs as well as ILC1/ILC2 ratio were presented: PBMCs from a healthy individual (B) or an OLP patient (C) were stimulated with different OLP plasma or normal plasma separately for 3 days. PBMCs from different healthy individuals (D) or OLP patients (E) were stimulated with mixed OLP plasma or mixed normal plasma separately for 3 days. Data are depicted in before–after plots or as a bar graph with mean ± SEM. Two-tailed unpaired Mann–Whitney tests and paired t-tests were performed, *p < 0.05, **p < 0.01. PBMCs, peripheral blood mononuclear cells; OLP, oral lichen planus.
