Next, CD14 protein expression was analyzed in plasma (Figure 4A) and CSF samples (Figure 4B) from patients with Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis and from healthy controls (dilution of 1:2000 for plasma samples and 1:500 for CSF samples). The gene discussed is CD14; the disease is early-onset autosomal dominant Alzheimer disease.
