Doctors, thank you both for being here today. It's greatly appreciated. You definitely add to our study.
As you've heard from my colleague on the issue of how we know which soldiers have actually been exposed to mefloquine, we don't have those records. They were given a drug, and those records apparently don't exist. That's a big challenge. Ultimately, we do have soldiers who are suffering. They're presenting neurological and neuropsych disorders, and the challenge is whether the problem is mefloquine toxicity or PTSD.
In a perfect world, it would be great to have a protein—for example, the Bence-Jones protein, which makes it evident that a person has multiple myeloma—but we don't have that. What prompted this question, Dr. Sellers, is your earlier comment about a transport protein that gets mefloquine out of the brain. I'm interested to hear a little more about that. Is that new research? Is that purely being theorized? I wonder if you could tell us.
