HGF and infectious meningitis: CSF samples from patients with septic meningitis (including both community-acquired and nosocomial) was significantly higher in HGF concentrations (p = 0.0014), HGF binding to HSPG (p < 0.0001), and HGF binding to c-Met (p < 0.0001) compared to samples from patients with aseptic (viral and subacute) meningitis.
