Imbalance of regulatory and cytotoxic SARS-CoV-2-reactive CD4+ T cells in COVID-19
The contribution of CD4 + T cells to protective or pathogenic immune responses to SARS-CoV-2 infection remains unknown. In this paper it’s presented single-cell transcriptomic analysis of >100,000 viral antigen-reactive CD4 + T cells from 40 COVID-19 patients. In hospitalized patients compared to non-hospitalized patients, were found increased proportions of cytotoxic follicular helper (T FH
