Antibody Discovered To Boost HIV Vaccines

Posted by kdawson on Friday July 9, 2010 @05:26AM from the nowhere-to-hide dept.

An anonymous reader sends this clip from Scienceblog.com. "Scientists have discovered two potent human antibodies that can stop more than 90 percent of known global HIV strains from infecting human cells in the laboratory, and have demonstrated how one of these disease-fighting proteins accomplishes this feat. ... Research efforts to find individual antibodies that can neutralize HIV strains have been difficult because the virus continuously changes its surface proteins to evade recognition by the immune system. As a consequence of these changes, an enormous number of HIV variants exist worldwide. However, there are a few surface areas that remain nearly constant across all variants of HIV and scientists have now discovered two potent human antibodies that attach to one of these sites and can stop more than 90 percent of known global HIV strains from infecting human cells in the laboratory. ... The researchers also confirmed that VRC01 does not bind to human cells — a characteristic that might otherwise lead to its elimination during immune development, a natural mechanism the body employs to prevent autoimmune disease."

But I have to wonder if the region that doesn't normally morph will start morphing if it starts being targetted. HIV is a tough little bugger. Very borg-like.

  What that really depends on is whether multiple strains infect the same individual. If, as you suggest, each individual is infected by 1 strain, then this solution indeed would cure 90% of the population (assuming it works). However, if each individual is infected by 500 strains, this solution will cure a tiny fraction of 1% of the population.

  Eh, as long as we're talking about infection rates and cure speeds, you should also note that they aren't going to cure 90% of those with HIV (or vaccinate everyone so those 90% of HIV strains stop spreading). The vaccination rate will be slow, not instantaneous, and it will give time for the other 10% of strains to fill the void. How many lives are saved depends on how quickly the vaccination moves out, how many people get it, and how quickly the other strains spread.
  
  Incidentally, condoms work so well at preventing HIV from spreading that if everyone used them, the propagation rate of HIV would likely be dropped below a sustainable level, and AIDS would disappear. In Nevada brothels that use condoms, HIV rates are quite low.

  Viruses and germs that evolve around an antibody or antibiotic tend to be less virulent than the wild strain. Without the antibody or antibiotic, the wild strain has predominated against all other strains, including the resistant strain. The resistant strain tends to be less efficient at survival than the wild strain. If the strains of HIV that are best able to bind with human immune cells are knocked out, the ten percent left may be less able to spread than the existing strains. If you assume that the spread of a contagion has exponential (to some degree) a drop in the transmission rates may save many, many lives.
  The problem with HIV is that its effects can be mitigated if people use condoms, not be so promiscuous, and stay away from risky practices such as anal sex or dry sex. The risk of getting HIV from non-anal heterosexual intercourse is very small; studies put it at 1 in 500 if you have vaginal sex with a HIV-infected person. Using a condom makes that risk effectively 0. We need to educate everyone to avoid these practices. This would mitigate the spread of this plague.

  In the long term, certainly yes, variants of disease that are are not recognized by the immune system or resistant to existing treatments will spread again, even from a small core, perhaps one created by accidental mutations. Influenza, of course, manages to do so every year, demonstrating how efficient viruses can be at playing this game. Experience with bacteria and parasites (malaria) is also rather discouraging.
  However, how fast that occurs depends on quite a number of factors, including the ability of those mutant viruses to replicate, infect, and cause disease; and of course their geographical spread. Characteristic for many treatment-resistant mutants of HIV is that they are less virulent, because their optimal functioning as a virus has been compromised. Resistance mutations are known to all existing antiviral drugs, and it is only a matter of time before these resistant viruses will become more frequent, but meanwhile the drugs do increase the life expectancy of most patients by about thirty years. In reality, partial solutions are worth the effort. Imagine for a moment that you would have a vaccine that would largely eliminate HIV-1 subtype C, which accounts for over half the infections in the worlds poorest countries. That might be worth having, even if it is only a "short-term" solution and the virus will reconquer the lost terrain.
  Unfortunately, in this case it is not clear from the information that I can access, what the practical implications of those 10% of viruses that escape the potential treatment are. The summary mentions 90% of HIV-1 strains, but actually the abstract in Science claims 90% of isolates. I can't access the article from here, but probably the authors identified the sequence of the binding site for their antibody, and then looked how frequently this occurs in a database of known HIV sequences, probably the Los Alamos database. That number doesn't tell you much about the viruses in which is does not occur.

  Based on a few papers I found and a few quick, back-of-the-envelope calculations, it should help at least 10.3% of the infected population and at best will help 96%. The huge amount of variability comes from not knowing much about superinfection in HIV. I'd also like to know what strains VRC01 and VRC02 specifically /don't/ target; if the researchers are referring to HIV-1M, O, and N and HIV-2, then "over 90%" means 23/25 is covered, so I'm betting HIV-1N [see http://commons.wikimedia.org/wiki/File:HIV-SIV-phylogenetic-tree.svg ]---but, who knows.
  Anyway---for every 100 person-years, there will be a few HIV reinfections in HIV-positive individuals, sometimes by viruses of the same exact subtype, sometimes by viruses of differing subtypes. Sometimes the viruses are more virulent than the original infecting strain of HIV. The time elapsed since the original HIV infection does not seem to make an impact on the distribution of times of second HIV infections. (Yes, I know that sentence could use re-wording, but exactly how is eluding me atm.)
  http://jama.ama-assn.org/cgi/content/full/292/10/1177 suggests 5.0 reinfections per 100 person-years (population size 78) in SoCal, http://www.plospathogens.org/article/info%3Adoi%2F10.1371%2Fjournal.ppat.0030177 suggests 3.7% reinfections (population size 36) per 100 person-years in Kenya, and http://jvi.asm.org/cgi/content/full/79/16/10701?ijkey=30fccead91569e63031af4357a242da634620d52#SEC3 suggests 10.3 reinfections per 100 person-years (population size 20). A weighted average of these numbers, where the weights are the population sizes (not the best approach, but given the sparse amount of data found in the literature about this particular topic in general, it's better than no weighting, perhaps), comes out to 5.0 reinfections [reinfection or superinfection is very hard to define for HIV---see the methodology in the second article for more information about this] per 100 person-years. So if we look at http://en.wikipedia.org/wiki/File:HIV_time.png a timeline...
  If we assume the number of reinfections a year is simply the reinfection rate (5.0/100 to get per-year) multiplied by the HIV-positive population that year, and guess that none of the population in 1980 (where the timeline starts) was superinfected, we get 22.7 million in 2008. If the population in 1980 had all been superinfected, we get 30.0 million in 2008.
  On the other hand, if we assume that only the increment in HIV-positive population is eligible for reinfection (a lousy assumption, but with how little is known, it's as good as any---actually, I'm partly going off of the notes in the introduction of the second article about the known information about reinfection rates), and just multiple the difference from year-to-year in the HIV-positive population by the reinfection rate, we get 1.31 million. (It would not make sense to include the 1980 population here, based on the assumption made.)
  We don't really know enough to guess, but we can probably assume there would be at least an easily noticeable impact. A 10% drop in HIV population would be very obvious---that's a few million people.

  And for your next trick will you redefine chocolate as "tastes like liver" or soft as "consistency of concrete"? "Wedlock", regardless of the goal, still implies multiple people. Are you suggesting that Minnie Driver, going back to my example, would have to "enter into wedlock" with herself?
  As for the rest of your batshit insanity, this is why you don't get to make the rules. The rest of us, you know; the not-crazy people, don't think any of your reasons for killing people make any sense.
  Oh, since I'm here anyway, "deadbeat dads" are not single parents in the traditional sense. The custodial parent, the one that the "deadbeat" owes the child-support to, is the single parent. We also don't typically lock them up. If you owe child support, and suddenly find, through no fault of your own, that you can no longer afford that amount, you return to court and renegotiate it. The people who get locked up are [supposed to be] the ones who *refuse* to pay their child-support, not the ones who can't because they lost their job.

I fail to see the hype. There are plenty of great anti-HIV antibodies which are well described. These have a great cross-reactivity to many HIV strains and are directed against very conserved regions of envelope proteins. The trouble lies that no one so far has been able to find a way to produce them in a patient's body in large amounts. In addition, it is well known that Ab response is not really the way to go. Current HIV vaccines designs are moving towards inducing a innate immunity responses and also focus on T-cell not B-cell mediated immunity.

If my memory of microbiology serves me correctly, the variance in HIV has more to do with the super error-prone reverse transcription process than it does with the virus actually trying to evade destruction.

  Look. Either kill the brats that people produce and can't afford, or punish the people that produce the brats. But, certainly stop forcing other people to pay for the bastards.
  Otherwise, with HIV treatments and possible cures improving, you will have more people blase about unprotected sex and unwanted kids demanding that the rest of us support them. Their kids will grow up to do the same, and their sheer numbers in a democratic society will result in enslavement of the responsible to support the lifestyle of the irresponsible.
  Producing children you can't support should be one of the most heinous crimes there is, and punished accordingly.
  What's with the Hitler reference, anyway? In my call to punish sexual irresponsibility with death, I do not discriminate on the basis of race, religion, gender, or national origin.
  If this is somehow unfair, because it has become so expensive to actually raise children, perhaps resources have been spread too thin, and the human species needs some serious culling to return to sustainable numbers for a larger fraction of the population. This achieves that too.

  Killing those who can't restrain themselves, and can't afford their "mistakes", is an unbiased means of achieving this.
  Does this discriminate against the poor? Only to the extent of punishing them for living beyond their means through irresponsibility: there is no right to "have" what someone else does.

If you can afford it. If they come up with a cure for AIDS/HIV, whats it worth to the person who is afflicted with it? What isn't it worth. They could easily patent it, then peg the cost at $20000 US per treatment. The rich will get treated, the drug companies will make a fortune, the researcher will get more funding for further research, but I won't hold my breath on the average person who is afflicted seeing any benefits from this until the patents have expired.
