Previous studies indicated that in the top 3 genes, VCAM1 was involved in both lymphocyte activation in OLP and autoimmune response in HT.[20,21] To further confirm the interactions between VCAM1 expression and immune infiltration, the CIBERSORT algorithm was used to analyze the proportion of 22 immune cell types in OLP and HT. Here, VCAM1 is linked to hematocrit.
