Since I found this pretty interesting and my school has subscriptions to a number of scientific journals, I looked up the full paper on PubMed (
here's a link to the abstract if anyone's interested).
Actually, after having there body attacks by so many harmful organisms, their immune system has become very strong and is able to fight off the HIV virus...so...overly strong immune systems can even stop AIDS, it just takes years of workin' the corner...which, none of us will ever be doing, right guys?
Haha, not quite. Previous exposure to other infectious agents would not give them any advantage against a completely different type of virus. Besides, all of the women in this study were chosen because they did not have any other STDs or infections (doesn't say this in the article, but it's in the full paper).
I think it has more to do with genetics than their immune system adapting to the virus. From what I could glean from the not very descriptive article the make more of a certain type of protein than what most women make in their ****** (which is extremely acidic already).
Yeah, differences in their DNA are the most probable cause. The women who were resistant to infection (by the way, the researchers defined "resistant" as being involved in sex work for 3 years and remaining uninfected) overexpressed 8 proteins and underexpressed 9 proteins.
I'm not sure where the authors of the article got the idea of a "vaccine". I don't think this could necessarily be used to create a vaccine, but it could certainly be used (after more research of course) to create a treatment through medication that affects expression of those proteins and possibly gene therapy. It would probably be expensive. Either way, this is a pretty cool breakthrough.
What exactly do you mean? It's been known for years that anybody (whether homosexual or heterosexual) is susceptible to HIV, and ultimately AIDS.
Unless you meant something different?
When HIV/AIDS first emerged, it was mostly in the homosexual population; for a while, people thought it was a "gay disease" until it started showing up in heterosexuals too.
The FDA currently prohibits gay men from donating blood. This is probably because homosexual contact is the leading cause of transmission of HIV in the US, and the gap between when someone first gets infected with HIV and when it shows up on blood tests. Homosexuals are also less likely to use protection during sex, since the main reason a lot of people use protection is to prevent pregnancy and homosexuals don't have to worry about that. Still, the rule seems pretty outdated and I'm not sure why the FDA still maintains the ban.
