Gene Found In Black Death Survivors Stops HIV 477

Posted by Zonk from the research-halted-at-politician's-request dept.
WindozeSux writes "According to research done by Dr. Stephen O'Brien, a mutated gene known as delta 32 found in Black Death survivor descendants, stops HIV in its tracks. In order to be immune both parents have to have the delta 32 gene. From the Article: 'In 1996, research showed that delta 32 prevents HIV from entering human cells and infecting the body. O'Brien thought this principle could be applied to the plague bacteria, which affects the body in a similar manner. To determine whether the Eyam plague survivors may have carried delta 32, O'Brien tested the DNA of their modern-day descendents...'"

          Not when the Vatican and religious leaders have been telling them that not only do condoms not prevent HIV infection, but are laced with HIV themselves: [guardian.co.uk]

          The Catholic Church is telling people in countries stricken by Aids not to use condoms because they have tiny holes in them through which HIV can pass - potentially exposing thousands of people to risk.

          The church is making the claims across four continents despite a widespread scientific consensus that condoms are impermeable to HIV.

          Sex and the Holy City includes a Catholic nun advising her HIV-infected choirmaster against using condoms with his wife because "the virus can pass through".

          In Lwak, near Lake Victoria, the director of an Aids testing centre says he cannot distribute condoms because of church opposition. Gordon Wambi told the programme: "Some priests have even been saying that condoms are laced with HIV/Aids."

        Ah, but something encouraged the development of multiple redundant pathways. I suspect that what happened is that a second pathway randomly developed many years ago (probably before modern humans). After that, something came along that killed everyone off who only had the single pathway. I'm speculating that it's a disease, but it could be aliens who had it out for single pathway humans - that's evolution for ya. After my imagined catastrophe, the survivors still had two pathways. This likely had an extra metabolic cost, but it was fairly miniscule.

        Human DNA has an awful lot of redundancies in it. I sometimes wonder how many protiens are expressed that just float around not doing much. Most bacteria have trim and efficient DNA. That keeps their energy expenditures low, letting them focus on important things like reproduction. Humans, on the other hand, have a surprising amount of extra stuff collected along the way. It turns out that being extremely efficient isn't a big survival trait for humans.

          You mention a very, very interesting fact, which blew me away when I learned it about our genetics. What is it with (1) all this pointless intron DNA, and (2) all this God-damned splicing? Why don't the prokaryotes do that stuff? This is, as you say, weird.

          So is it an accident? Given that there've been only about 10^5 generations of homo sapiens, whereas bacteria do that every 2-3 years, and they've been around billions of years -- is it just that we've not evolved as far as they? Will our DNA be a lot tighter in 30,000,000 AD (assuming we survive at all)?

          Or is there some reason designed in by...(audience holds breath)...no, not God for, uh, Christ's sake...but by natural selection that gives us an advantage with all this DNA swapping?

          Have I not heard the thought that it might be because a bacteria's big problem is a hostile environment and his lack of ability to manipulate it other than eating it, whereas one of our big problems (before modern medicine) was fighting off viral attackers? And, if that's the case, this screwball shuffling around of the DNA, plus "hiding" the real genes amongst acres of useless, identical-looking trash are clever techniques for making us much more elusive targets for viruses.

          Joe Virus successfully invades the pathetic human cell, sneaking past the killer white cells, snipping the wire and snaking under the membrane while the guard dogs howl....he makes it! Cleverly picks the lock on the super-secure citadel of the nucleus, gets out his dynamite, blows the doors off the chromatid fiber, and, chortling, inserts his DNA sequence into the host DNA.

          But alas for Joe, 90% of the DNA is never used, and so Joe has a 90% chance of having inserted himself into a string of rubbish that will never be transcribed. Poor bastard, waiting and waiting...

          Now to get back on topic, I've also heard that one caution people have about gene therapy (such as slipping in a gene that protects against HIV) is that if there are these ancient unexpressed viruses lying about in our DNA, what might we do if we muck around with it by slipping in some new genes? Might we accidentally "turn on" a virus dormant since the next to last Ice Age? If it's just a Neanderthal version of a head cold, big deal -- but what if it's something far worse than AIDS itself? As fatal as AIDS, say, but with a 60 day mean survival time and the ability to be spread through the air? Brrr.

            While much of your post is generally on the fringes of what we know, I can say with general certainty that the answers to these questions is "No" and "No."

            For the first question, one shouldn't leap to the conclusion that the number of generations equates to evolutionary success. The two aren't necessarily related. Remember, evolution is essentially about the filling of available biological niches. The niches that humans and bacteria fill are vastly different. In light of this, calling one type of successful species "more evolved" than vastly different, yet also successful, species really carries little meaning. Perhaps a better way of putting it is this: Evolution is not forward-looking. There is no beginning, middle, or end to the evolutionary path of a species. Any species present today (simply by virtue of the fact that it has survived) is just as "evolved" as any other.

            For the second question, I seriously doubt our genome will (naturally) become smaller over time. Unlike bacteria, finding the extra nutrient sources to accommodate the amount of unused DNA or non-useful protein products doesn't appear to be a selective pressure. I'd suspect that this is because such an inefficiency is relatively minor for a large multi-cellular omnivore such as us and wasn't an evolutionary driving force in the past nor will be in the future.

            Lastly, I'm suspicious to call the DNA whose function remains unknown "junk DNA" as others do. Who's to say that it doesn't serve a purpose simply because we lack a theory for one? To do so reeks of scientific arrogance.

            That's not quite true. Many retroviruses and retrotransposons carry their own promoter sequences with them, so they increase the chance of transcription by the cellular machinery. It gets trickier when you have something like SINES, however, which lack promoter elements. They basically cluster near LINES, which carry promoter activity, so that the SINES get transcribed

    Things like this put an interesting spin on science in general. Trying not to be off topic here, but if we are to reach anything like a utopian state (think Star Trek here) then we, as a race, have to overcome quite a few thresholds. The number of people on the planet is one, the fact that modern medicine is allowing more mutations to survive, including weak mutations (read that as mutations that weaken the population over time rather than insert survival traits like immunity to AIDS).

    The things that we are doing through science for money is going to become a wall that will stop us in the future, or can. Right now, it is unknown if our vegetable and foodstuffs are actually as valuable to the human body as they are supposed to be. I'm not talking about hamburgers, but raw vegetables. Pesticides and genetic modifications of crops is changing how they are used by the body.

    Its not improbable that scientists could insert the immunity genes via foodstuffs in the near future, rather like making us all part of a super race... or rather the benefactors of the genetic makeup of superhumans. This process, in the course of history, has always wiped much of the world clean of the weaker specimens, leaving those with the stronger mutations to live on. That in turn drags down the rest of the population as genetic weakness is passed on.

    This is a reasonable idea, just give the good genes to everyone.... but morally, that is the wrong thing to do. It will turn out that only those with an extra $150k will get the therapy... no insurance will cover it, 3rd world citizens can't buy it, and its not so different than what some of Hitler's folks were attempting to do (at least in some respects) ...

      As China and India become more prosperous, they too will join the club.

      In short, the "Population Bomb" was a dud.

        I agree that "overpopulation" will not be a problem in the future. However, the above strikes me as a little too rational and informed. I'd attribute people's choices more to selfishness than anything else: there are simply so many more choices and opportunities available today than there were in the past, so people are more reluctant to
    • I have thought about the possibility of a uptopian society for a while, and have come to the following conclusion:

      There are two ways to eliminate poverty and allow all members of a society to function cooperatively as a whole. You can either drastically alter human nature to the point where no one desires personal gain through another's loss (unless the overall gain for the society is positive, in which case it is justified). The second option is to remove all possibility for any individual to harm another

    Nobody seems to have noticed that TFA is just a summary of a TV show. And one that doesn't seem to have that much to say about Delta 32 either. Anyway, judging from Google, Delta 32 is old news.

    The CCR5 gene (which includes the CC5's with the delta 32 mutation) is on chromosome #3. You can look over the DNA code (nucleotides, codons etc.) and get more information on a number of sites:

    UCSC Genome browser [ucsc.edu] - has the whole gene, but you can zoom in on segments if you want.

    NIH [nih.gov] - this has links or links to links of everything you'd want to know.

  • So one guy is immune to HIV. We use virus carriers to alter our DNA to include that particular gene. Another guy is immune to so and so cancer. We all get that gene too, the way we get flu shots.

    So in a few decades, do we all look alike? Do we all become equally vulnerable to a new strain?

      They've even started banning shows that birds are appearing in, for fear of infecting the general population.

      Idiots.

      I feel like beating the editors with repeatedly with a cluebat. All the birds have *bird* flu. Not human flu. Humans are not birds. We do not have feathers, and cannot fly. Neither are we parrots. Which are also birds. Even dead parrots.

      If/When the virus:

      (a) jumps the species gap (which there's evidence it has done already a few times),
      and (here's the kicker...) (b) the mutation can not only survive, but transfer to other human hosts (this hasn't happened yet) then there will be an issue.

      Then it won't be bird flu any more. It'll be human flu.

      Caveat to (b) - it may lose virulence in the tranfer, and end up just like all the other flu outbreaks that the press don't like to talk about because they're not scary enough, like 1967.

      Oh, and (c) we know *just* a little bit more more about disease prevention than we did in 1918...

    is how this mutation got into the general population in the first place.

    The current operating theory [nih.gov], as I understand it, is that it originated (uhhh ... mutated?) somewhere in southern Finland [plosjournals.org], made it's way across the Baltic Sea to Sweden, and from there fanned out across Europe and West Asia during the period of Viking expansion -- from about the 8th-10th centuries.

    The mutation is found in native populations as far away as Cyprus and North Africa; but the closer you get to Scandinavia, the more prevalent it becomes. So, really, the Vikings were doing the rest of Europe a public service while they were casually burning it into the ground.
