Web27 apr. 2024 · By Sarah C.P. Williams. Researchers discovered a new antibody (light blue) that neutralizes the COVID-19 virus, by binding to the virus’s spike protein (grey) and locking it in a closed conformation. Inside the body of a person with COVID-19, the immune system’s B cells are engaged in a full-scale battle with the SARS-CoV-2 virus. WebPlasma B cells lose CD19 expression, but gain CD78, which is used to quantify these cells. Memory B cells can be immunophenotyped using CD20 and CD40 expression. The cells can be further categorized using CD80 and PDL-2 regardless of the type of immunoglobulin present on the cell surface (Zuccarino-Catania GV et al. Nat Immunol. 2014.).
