Objectives: Previous studies have demonstrated a potential role of brain endogenous microglia and meningeal macrophages in inflammation and neuronal injury in bacterial meningitis. However, the contribution of postnatally invading hematopoietic microglia to this process is still unknown. Methods: To investigate the kinetics of microglial engraftment we used genetically labelled bone marrow-derived cells (BMC) from transgenic mice driving GFP under the beta chicken actin pomotor to deliver fluorescence-labelled microglia to the diseased brain. 8 weeks after transplantation, 104CFU of S. pneumoniae were injected i…
