Impact of anti-vector immunity on transgene expression.

<p>(A) Anti-vector reactivity and (B) expression of ITS01 is shown for the six animals of <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1007395#ppat.1007395.g001" target="_blank">Fig 1</a>. Animals with low (A10V030; orange) and intermediate (A10V026; purple) pre-existing anti-vector immunity are highlighted. After 6 months, two of these animals were re-injected with 1 x 10<sup>13</sup> gc AAV8-ITS01 in the right quadriceps. (C) Anti-AAV8 reactivity was boosted, however (D) no increase in serum ITS01 was observed. Anti-AAV8 measurements are in arbitrary optical density (OD<sub>450nm</sub>)/ml units.</p>
