Lung-resident memory B cells produced during influenza are long-living immune cells that migrate to the lungs from draining lymph nodes and lie in wait as early responders that can quickly react to future infections. (uab.edu)
Unlike antibody-producing B cells that help fight the current infection, the long-lived, non-circulating lung-BRMs migrate to the lungs from draining lymph nodes. (uab.edu)
During influenza infection, both Tfh and B cells are present at germinal centers in the lymph nodes that drain the lungs. (uab.edu)
In mechanistic details, the researchers found that intrinsic IFN-γ-STAT1 signaling in B cells in the germinal center of lung-draining lymph nodes promoted expression of the T-bet transcription factor, and T-bet was necessary for differentiation into pre-memory B cells that express the surface marker CXCR3.
