Considering the prominent role of VEGFA and its receptor FLT1 in angiogenesis8, and increased immune cell infiltration corresponding with angiogenesis37, we analysed their gene expression in relation to macrophage marker, CD163, and a marker of blood vessel luminal cell adhesion, ICAM1. CD163 and ICAM1 mRNAs both positively correlated with VEGFA and FLT1 in schizophrenia (all Spearman’s rho ≥0.47, p ≤ 0.01). The gene discussed is ICAM1; the disease is schizophrenia.
