In response to SARS-CoV-2 S-RBD (Figure 2B) and SARS-CoV-2 ICL (Figure 2C), we observed significantly increased frequencies of CD8+ T cells expressing IFN-γ, IL-2, TNF-α, and IL-17A in MIS-C compared to children with COVID-19 and other infectious diseases. The gene discussed is IFNG; the disease is COVID-19.
