TABLE 2.
Plasma NDE levels of total synapsin 1 protein and P-S9-synapsin 1
| Protein | FTC | FTD | AC | AD |
|---|---|---|---|---|
| Synapsin 1 protein (pg/ml) | 2295 ± 138 | 7781 ± 1379** | 2048 ± 219 | 1058 ± 99** |
| P-S9-synapsin 1 (OD450 nm/ng synapsin 1) | 0.511 ± 0.050 | 0.118 ± 0.021** | 0.545 ± 0.081 | 0.270 ± 0.049* |
Each value is the mean ± sem for levels of the 16 patients with FTD and controls (FTC) or 12 patients with AD and controls (AC) in Fig. 1. Group differences were determined by an unpaired Student’s t test. *P < 0.01; **P < 0.001.
