"We appraised the evidence provided by both in vitro and in vivo work before proceeding to a critical assessment of the relevant clinical trial data. METHODS: Relevant literature was identified using a PubMed search of articles published up to October 2007. "

There lies the problem. The literature is full of inaccuracies and to a certain extent, controlled by the sponsors. Thus, you get a bunch of nothing; particularly shameless is the publication of this nothingness in journals where biased investigators in the actual research are EDITORS of the journals.

i do not make this up.....book coming soon! Guaranteed more accurate than any report about GDNF. Monkeys in the Middle....the toxicity report for GDNF can be found in a veterinarian's journal.

There was no toxicity in humans. They high dosed the monkeys.

Funny video! Of course entertainment comedians exagerrate.....in real life most people are much better at saying nothing.
