The flow cytometry gating strategies for SARS-CoV-2 Spike-protein-specific PBMC expression of CD4+IL-17 and CD8+IL-17 in stimulated and unstimulated samples of each MISC_A, MISC_C, COVID-19, and control patient are presented in Supplementary Figure S1 and Supplementary Figure S2, respectively. The gene discussed is IL17A; the disease is COVID-19.
