Researchers Block HIV Infection In Monkeys With Artificial Protein

Posted by Soulskill on from the winning-another-battle-in-a-long-war dept.

An anonymous reader writes: Immunologists have developed a synthetic molecule that's able to attach to HIV and prevent it from interacting with healthy cells. "HIV infects white blood cells by sequentially attaching to two receptors on their surfaces. First, HIV's own surface protein, gp120, docks on the cell's CD4 receptor. This attachment twists gp120 such that it exposes a region on the virus that can attach to the second cellular receptor, CCR5. The new construct combines a piece of CD4 with a smidgen of CCR5 and attaches both receptors to a piece of an antibody. In essence, the AIDS virus locks onto the construct, dubbed eCD4-Ig, as though it were attaching to a cell and thus is neutralized." The new compound was tested in monkeys. After successively higher injections of HIV, all four monkeys who received the compound beforehand stayed from free infection. Any potential medical treatment is still a ways off — the researchers plan more trials in monkeys before involving humans in the testing.

The biggest contribution will be that, as a result of trying to cure AIDS, we have learned immense, really truly immense, amounts about the immune system and it's incredible intricacies.

      And, guess what? Ultimately, it is the immune system that keeps your body free of cancer. Cancers happen frequently in your body, and the immune system beats them down. When it fails at that for some reason, only then does clinical disease happen. I've heard it said that most people have 6 or so small cancers in their bodies at any given time, all being properly managed by the immune system.

      Understanding the immune system, because we have been trying to cure a disease of the immune system, will eventually do more good for human health than any other single effort since the invention of antibiotics, with the possible exception of magnetic resonance imaging.

The National Institute of Allergy and Infections Diseases, the NIH that is charged with fighting AIDS, had $4.3B appropriated for FY15. Even if we assumed that the entire NIAID budget went to AIDS (and it does not), the NCI has a bigger budget. So the GP is just flat out wrong with his initial assertion: much less research effort in the form of NIH extramural support is spent on AIDS than on cancer.

      Hodgkin's Lymphoma is actually an outlier and a really useful example.

      Hodgkin's is caused by a very specific mutation. Relatively early on, they realised that if you can poison the mutated cells without killing the patient, they get better. And if you're lucky, they don't just get better, they stay better, it's a bona fide cure.

      This same idea (just kill the mutants) seems applicable to a lot of cancers, but Hodgkin's stands out because

      1. Lots of young people get it. We don't know exactly why, but men in their 20s get it a lot (compared to say, lung cancer or other types of cancer, which mostly old people get). This means your cure has a remarkable effect. Old people were going to die soon anyway, but a 25 year old man cured of Hodgkins may well live 40-50 more years. So you can be 100% sure it's working.

      2. One very specific cell that scientists already knew existed has one fairly obvious and easy to understand defect. They didn't know why yet, but the cells look all wrong under a microscope. Cured patients, and normal people who aren't sick don't have the characteristic cells. So if something kills those cells, but not the patient, it's a possible cure.

      There is a downside to all this. We've been curing Hodgkin's for longer than we've done proper scientific medicine. The people who invented a cure didn't run a double blind trial to see how well it worked. They tried it, cured some people and went "Good work, time to go home". So today we have NO CLUE how bad Hodgkin's is exactly. If you're untreated at say, Stage IIb, can you expect to die in a year? Two years? Five years? We really don't know. Some people refuse treatment, and those tend to die horrible deaths a few years later, riddled with cancer and other problems, but not enough of them exist to have any confidence in an estimate and they're crazy people who avoid doctors, so who knows if it's a bad for normal people who just can't get cancer drugs.

      Because we're sure it works it would be terribly unethical to run a trial now. You'd be condemning half the trial participants to death, just to prove a point! So we will probably never be sure.

      You're correct that this doesn't sound like a cure. On the other hand, it might be both a very effective vaccine for the uninfected, and a reliable treatment for those infected. (This depends mostly on HIV's ability to mutate these receptors into something that can reject the drug but still connect to the target cells.) Even if a vaccine isn't a cure, it can lead to eradication of the disease. The smallpox vaccine wasn't a cure either, for example, but with sufficient coverage it was quite effective.

    My understanding of HIV is that when it infects human cells, it hijacks the tRNA (iirc) so that the human cells continue producing more HIV viruses.

So this would seem like a race condition where the antibody needs to get to the HIV *before* HIV has a chance to infect a human cell. How can this happen reliably?

      Mostly through concentration: making sure there are 100x or more antibodies against HIV present than the cells HIV is targeting.
      But it's also helped by binding affinity. When a receptor and a substrate bind, it's generally reversible -- they can join or separate, and there is a measurable equilibrium between the bound and unbound states, which is a function of concentration of both receptor and substrate, and a constant that reflects how well they actually stick together. Generally, antibodies are _vastly_ better at sticking to things because they're designed to be. (Okay, the 'designed to be' is not actually true but for the purposes of this, it's an okay approximation) So if your antibody/HIV binding affinity is 100x better than the HIV/cell binding affinity, and you have 100x more antibodies than target cells, the number of viral/cell bindings is going to be much lower than the number of antibody/viral bindings.

    If you can cause the protein to be generated in the blood, why not also treat cells on the brain side of the blood-brain barrier as well to produce the protein and so protect the brain?

    If you can do that, you can halt transmission to new people, and halt progression of the disease on both sides of the blood-brain barrier, it's about as close to a cure as could be achieved without actually destroying all the quiescent viruses.

    Heck, it might actually cause less damage to the host than destroying all the quiescent viruses--the host cells are still sort of functional, but if you killed them all, their functions would fail completely.

    See for example the antiviral treatment in research, which causes infected cells to die:
    http://en.wikipedia.org/wiki/D...

    A worry with this treatment is that many nerve cells are infected with herpesvirus in some people, and simply taking these cells out may result in far more damage than desired. Better to leave infected cells intact and enforce dormancy, which protects hosts and prevents spread.
