MASP2 and pneumococcal meningitis: To study whether MASP-2 was expressed in our pneumococcal meningitis mouse model [21], WT mice were injected into the cisterna magna with S. pneumoniae serotype 3 (ATCC 6303; n = 15) or sterile saline (n = 5) and sacrificed at 6, 24, or 48 h (n = 5 per time point).
