HGF and early-onset autosomal dominant Alzheimer disease: CSF samples from patients with septic meningitis was higher from samples from the control group (patients with normal CSF) and from patients with Alzheimer’s disease in HGF concentration (p < 0.0001, p = 0.0010, respectively), HGF binding to HSPG (p < 0.0001 and p = 0.9, respectively), and HGF binding to c-Met (both p < 0.0001).
