FOLR2 and hypoxia: Comparing these 4 IM subpopulations in hypoxic-PH to the 3 populations in Schistosoma-PH identified that the Schistosoma-PH CCR2+ IMs were analogous to the hypoxia-PH MHCIIhiCCR2+EAR+ IMs; the Schistosoma-PH MHCIIhi IMs were analogous to the hypoxia-PH MHCIIhiCCR2+EAR- IMs; and the Schistosoma-PH FOLR2+ IMs were analogous to a combination of the TLF+VCAMhi and TLF+VCAMlo IMs in the hypoxia-PH model (Supplementary Figure S19).
