Initial definition and assessment of human antigen-specific SARS-CoV-2 T cell responses are best made with direct ex vivo T cell assays using broad-based epitope pools, such as MPs, and assays capable of detecting T cells of unknown cytokine polarization and functional attributes. Data from both the epitope MPs and protein peptide pool experiments can be interpreted in the context of previously reported T cell response immunodominance patterns observed for other coronaviruses, particularly the SARS and MERS viruses, which have been studied in humans, HLA-transgenic mice, wild-type mice and other species. (C) Correlation of SARS-CoV-2−specific CD4 + T cells detected using the epitope prediction approach (CD4_R MP) compared against the sum total of all antigen pools of overlapping peptides (excluding spike), run with samples from the same donors in two different experiment series. ./cache/cord-294429-isivkz8b.txt ./txt/cord-294429-isivkz8b.txt
