Ok.....this is a spin-off from the "Nerve Regeneration" thread I just started. I mentioned the commonality of PPARs in it.
I see now, that a researcher has found the same thing I was about to post (several abstracts), so I'll save time and just post his synopsis, which I retrieved from the NMSS website. He has been given a pretty large grant to proceed with his research. This sounds promising:
