How Are Memory B Cells and Long-Term Immune Memory Made?
The current COVID-19 climate means that now, it isn’t just immunologists who want to know how our bodies respond to re-infections months or years after an initial immune response. A new study shows that this ability requires Bach2, a protein that regulates the expression of genes needed to instruct activated B cells under selection to become memory B cells.
