Pathway analysis of dysregulated genes in granulocytes and platelets of PV patients. Pathway enrichment analysis of dysregulated genes in granulocytes (A) and platelets (B) was performed by using the Reactome database. FCERI, Fc epsilon receptor; FDR, false discovery rate; LAB, linker for activation of B cells; LAT1, L-type amino acid transporter 1; MAPK, mitogen-activated protein kinase; MHC, major histocompatibility complex; NTAL, non–T cell activation linker.
