Prolonged evolution of the human B cell response to SARS-CoV-2 infection
+CD27 + B cells at each sampling time point (top). Mean frequencies of SARS-CoV-2 S-specific B cells expressing the indicated isotype in mild and severe donors (bottom). Error bars denote standard deviation and black bars indicate means. (F) Proportion of SARS-CoV-2 S-specific swIg + B cells that express CD71 at each sampling time point (top). Mean frequencies of SARS-CoV-2 S-specific swIg +CD71 + B cells in mild and severe donors (bottom). Error bars denote standard deviation and black bars indicate means. The dotted line indicates the level of CD71 expression on swIg + B cells in pre-pandem...
