Extended Data Fig. 1: Schematic overview of specific T cell analysis in BALF and PBMC samples from COVID-19 patients.

(a) Schematic overview illustrating the comprehensive analysis workflow of BALF and PBMC samples. The analysis includes flow cytometry, 10x single-cell RNA and TCR sequencing, and Smart-seq2 single-cell sequencing. (b) Flowcytometric gating strategy for identifying SARS-CoV-2-specific T cells in PBMC and BALF samples.
