We apply these models to public TCR data and show how they can be used to study T-cell longitudinal profiles in COVID-19 patients to characterize how the adaptive immune system reacts to the SARS-CoV-2 virus. No other epitopes present in TCRex (including the 49 non-SARS-CoV-2 models) were predicted to have a single TCR target within this data set. Once established, these models can be applied to any TCR repertoire data and thus can be used to study putative SARS-CoV-2 reactive T cells in the currently available COVID-19 data. In addition, using such models on longitudinal data reveals a potential difference in temporal dynamics between T cells predicted to react against epitopes that are unique to SARS-CoV-2 and those that are shared among other coronaviruses. ./cache/cord-271849-wxmr8eki.txt ./txt/cord-271849-wxmr8eki.txt
