| Immune | 10/FXN | 31.5 | 3.1 | 5.8 | 6.1 | 0.2 | 53.2 | ||
| 2 | Intravenous | Naive | 9/mCherry | 41.3 | 5.2 | 6.3 | 1.9 | 0.1 | 45.1 |
| Immune | 9/FXN | 45.4 | 3.3 | 4.1 | 8.6 | 0.1 | 38.4 | ||

| Immune | 10/FXN | 11.4 | 2.1 | 1.8 | 7.2 | 14.5 | 63.0 | ||
| 4 | Intracisternal | Naive | 9/mCherry | 9.4 | 9.5 | 0.2 | 0.5 | 12.6 | 67.8 |
| Immune | 9/FXN | 26.6 | 3.2 | 2.1 | 6.4 | 21.5 | 40.2 | ||
| 5 | Intracisternal | Naive | 9/mCherry | 20.2 | 5.0 | 2.6 | 1.8 | 4.0 | 66.4 |
| 6 | Intracisternal | NaI control | I-124 alone | 2.4 | 1.5 | 0.4 | 0.1 | 0.1 | 95.4 |
| Intravenous | NaI control | I-124 alone | 6.3 | 4.5 | 0.6 | 0.5 | 0.1 | 87.9 |
The percentage distribution for each organ is equal to 100*aoi where the distribution fractions aoi were calculated from Equation (1).
See Table 1 for description of NHP, immune status, and description of the AAV vectors.
Body activity represents all I-124 activity that was not assigned to the five organs listed or the thyroid.
CSF, cerebral spinal fluid.
