Our analysis revealed that ANPEP and ENPEP expression is highly associated with the immune infiltration of macrophages, monocytes, DCs and NK cells (Figure 4), suggesting that ANPEP and ENPEP can play an important role in cellular immunity by regulating the immune infiltrate during GBM-affected by SARS-CoV-2. The gene discussed is ENPEP; the disease is glioblastoma.
