EBV Reprograms B Cells in an Autoimmune-Like Fashion in Patients with COVID-19
Epstein-Barr virus (EBV) reprograms B cells in autoimmune disease. Reprogrammed EBV+ B cells activate nearby B and CD4+ T cells, via upregulated antigen presentation and costimulatory machinery, to drive autoimmune pathology.
