IL2 and COVID-19: Similarly, in response to SARS-CoV-2 S+S1 (Figure 2C), SARS-CoV-2 M+N (Figure 2D) and SARS-CoV-2 WCL (Figure 2E), late convalescent COVID-19 individuals exhibited significantly elevated frequencies of mono- or dual-functional Th1/Th17 cells and in the case of SARS-CoV-2 M+N and SARS-CoV-2 WCL, multi-functional Th1 (IFN-γ/IL-2/TNF-α co-expressing) cells as well.
