Researchers describe six subsets of memory B cells — including one subset that produces the transcription factor T-bet. Using detailed genetic analysis and manipulation, they show that continuous T-bet expression in these cells is key to preserving the protective B-cell memory response. In a mouse influenza model, they found that T-bet expression was required for the persistence of lung and lymph node memory B cells that have rapid differentiation potential to become antibody-producing plasma cells.
