We did a further investigation and found that NRP1 was highly expressed in the TGF-β dominant immune subtype in all of these seven cancer types (Figures 6B–H), indicating that the TGF-β dominant immune subtype might be more susceptible to SARS-CoV-2 infection than other immune subtypes among LGG, BRCA, KIRC, PCPG, LUSC, COAD, and STAD patients. This evidence concerns the gene TGFB1 and cancer.
