New Drug Could Cure Nearly Any Viral Infection
HardYakka writes "A team of researchers at MIT's Lincoln Laboratory have designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection. The researchers tested their drug against 15 viruses, and found it was effective against all of them — including rhinoviruses that cause the common cold, H1N1 influenza, a stomach virus, a polio virus, dengue fever and several other types of hemorrhagic fever."

This kind of story is one of the reasons that I love Slashdot so much. What a fantastic breakthrough (if it pans out).
For a drug that cures any virus to work, it has to work in a manner that keeps the profits up for big pharma and the medical industry in general. If it doesn't do that, you can't have it.

What exactly does this do to the host organism (us) that is carrying these infected (and sub sequentially killed off) cells?
Since I don't speak micro-biologist, I'm not sure that was even addressed or answered in the article.

With the existence of auto-immune disorders as a warning sign, I can see that this will have lots and lots of trouble getting approval.
The only nasty side effect that might take place is a huge leap in the evolution of viruses. The stuff that does survive will be some extremely nasty sci-fi shit, including, I wouldn't be surprised, viruses that "hold the body hostage" by infecting critical cells and the biological equivalent of polymorphic viruses.

Given that some 8% of the human genome is from retroviruses, some of which may be expressed in some way, perhaps not all the time, -- with good or bad consequences, what side effects may we expect if this 8% causes some cells to be identified as infected? Could it result in huge cell death ?
Yeah, that sounds a lot like HIV.
But to be fair, this drug will only handle certain types of viruses (specifically long double-stranded RNA viruses). Fortunately, many of the nasty ones are of this type.
I don't want it curing me of life, i quite enjoy this disease.
What do I know, I'm just an idiot, right?
If there were even a tiny fraction of exceptions, things would get very ugly...
Here's the abstract of the paper. Note that the summary forgot to mention that the drug has been tested in normal cell lines as well. Also not mentioned is that all of this testing in live animals (not the cell lines) has been in mice and lots and lots of things go wrong when taking a drug developed in a mouse model to humans. It helps a lot that some of the normal cell lines shown to be unaffected were human.
Currently there are relatively few antiviral therapeutics, and most which do exist are highly pathogen-specific or have other disadvantages. We have developed a new broad-spectrum antiviral approach, dubbed Double-stranded RNA (dsRNA) Activated Caspase Oligomerizer (DRACO) that selectively induces apoptosis in cells containing viral dsRNA, rapidly killing infected cells without harming uninfected cells. We have created DRACOs and shown that they are nontoxic in 11 mammalian cell types and effective against 15 different viruses, including dengue flavivirus, Amapari and Tacaribe arenaviruses, Guama bunyavirus, and H1N1 influenza. We have also demonstrated that DRACOs can rescue mice challenged with H1N1 influenza. DRACOs have the potential to be effective therapeutics or prophylactics for numerous clinical and priority viruses, due to the broad-spectrum sensitivity of the dsRNA detection domain, the potent activity of the apoptosis induction domain, and the novel direct linkage between the two which viruses have never encountered.
As some posters suggested, there might be problems with herpes-style infections where the virus has infected nerve cells and gone dormant. The authors did not mention this in the paper as far as I could tell.

Slashdot: Where opinions are just opinions until you have mod points.
The rule-of-thumb is for every human cell there are 10 bacteria and 100 viruses living together in [ mostly ] symbiotic harmony. But bulkwise, due to miniscule size of these symbiots, bacteria only occupy a couple percent of weight and viruses a fraction of a percent. A tiny minority go berserk or are foreign invaders, thus cause some diseases.
The question is how does medicine distinguish the between the useful viruses and bad viruses?
Both of those already exist. HIV in particular does both.
Yes that's exactly the point. Just like its no problem for healthy normal humans if 0.001% of staph bacteria are antibiotic resistant... The problem is when you kill ALL the other staph bacteria so the population becomes 100% antibiotic resistant. Then you got a big problem, especially if that resistance cross pollinates into other bacteria.
So if you wipe almost all viruses off the face of the earth except HIV, then pretty much all viruses, are going to take on the characteristics of HIV. Including the common cold. Then we're pretty much screwed.

So this one drug finds ANY cell infected with ANY virus and kills it? That sounds dangerous as hell. Aren't viral infections partially responsible for genetic mutations vital to evolution. I don't know of any specific examples in our own genome; but isn't bee venom, for instance, derived partially from bits of genetic code from a virus. Who knows what leaps in evolution were fueled by snippets of viral DNA being incorporated with its hosts'. I think I'd like more information on this specific type of RNA that it targets. I smell a zombie apocalypse coming on.
I wonder, though, where a treatment like this leaves the human immune system.
A vaccine spurs the immune system to generate antibodies, so that when we're actually infected by the virus, the antibodies are available to combat it. Our own immune systems do all the work.
This new type of treatment, however, kills off the cells that have been infected by viruses, so the viruses aren't able to use the cell's materials to replicate. As the cells die, so do the viruses. From the sound of it, the treatment achieves this without any assistance from the immune system.
So to put it bluntly, in a world where everybody pops a few anti-flu pills every time they get a little sniffle, what does the human immune system do all day? I can see two possible outcomes:
Breakfast served all day!
Considering that there are some viruses that like nerve cells (eg: herpes), wouldn't it be a problem if said cells killed themselves? Having your CNS self destruct would ruin your day...
Kids! Have a cold? Take your Draco! Draco pills for everyone! Seriously, I'd be so happy to finally have a medicine with a cool name. Named after a Dragon. They could not have come up with a cooler acronym.
There are certain viruses that contain DNA, such as the ones that cause herpes. Although some of these replicate via a DNA-RNA-DNA path, others, I believe, replicate their DNA directly. Thus, these viruses would not be affected by the new treatment.

Why wouldn't you try it on the Virus that kills the most people and that you can make the most money off of?
Just because you are wrong and I called you out on it doesn't mean I am a Troll.
This is not correct. HIV, like the flu virus, has a single-stranded RNA genome that forms long helical, double stranded RNA structures which could be inhibited by this drug (DRACOs). See table 1 from the article, and my previous post
I don't know about cell infection rates of viruses but I worry about a drug that can kill off your own cells.
For instance: a virus(or multiple viruses) has infected 50% of you cells. Your cells continue to work normally for the most part(after all viruses use the normal cell operations to replicate). Then you take DRACO, your infected cells die within 24hrs. Again 50% infected cell is likely high(?). Do you think that you would feel an effect if 20% were infected? 10%?
As far as the detection of the viruses. They use a method of causing the cell to die when it detects long dsRNA(don't know what the ds stands for, wasn't covered in my high school science class) with strands >30 base pairs(They note that mammal cells generally don't produce dsRNA strands longer than 21~23 base pairs). So since viruses which contain only RNA get killed(along with the cell they infect). Though this leads to the possibility of viruses that have shorter RNA strands appearing(maybe?) or viruses that generate a blocking mechanism that prevents the collapse of the cell.
Call me when it's been published in NEJM, or JAMA or The Lancet. PLoS ONE is peer reviewed, kind of, but it's an "open access journal" and not exactly where you'd look for something of this magnitude. I'd imagine there are some serious problems if they couldn't get it published in one of the mainstream journals.

Disclaimer: I am a biologist, if not working in virology or molecular biology. I actually read the paper.
The findings that the group reports are very interesting - based on the Slashdot headline you wouldn't believe it, but it's actually legit science.
However, there's a big caveat. This drug is a protein, which is a very large molecule. Almost all currently marketed drugs are small molecules, which is a huge difference to the body. You will never be able to administer this drug orally, as to the body it is "food" and will be degraded in the stomach. If you inject it, cells will not take it up and it will not be effective. This is why they attached sequences to the protein that make transduction (crossing of cell membranes into cells) possible. These sequences come from somewhat "dodgy" sources. One of them is actually a part of HIV. It is completely unclear how the body will react to that. The construct might, for example, trigger an intense immune response.
That said, I am delighted to see this kind of work published. Basically, people are reaping the fruits of decades of basic research in molecular biology to design drugs that can be "programmed" to do whatever you want. If the technical limitations can be overcome (that is, once proteins can be delivered to cells very specifically and non-invasively and once the cell killing mechanism can be made super specific), great innovations in medicine will become possible.
One of them is actually a part of HIV.

I wonder if they could find/modify a basically harmless virus to "seek out" cancer cells, to act as 'markers', then use this drug to selectively destroy the cancer cells (having been infected by the cancer-seeking virus), while leaving non-cancer cells alone?
I wonder if Slashdot ever posted a headline with something like "Removing Lungs Prevents Lung Cancer" commenters would reply with "until we evolve a way to do it without lungs!"
This attacks the molecular things that are necessary for viruses to do the things that make them viruses. A virus could minimize the time that it does it in, or evolve a way to "signal" a mass production, but those are about the only ways it's even physically possible for viruses to deal with this kind of treatment. HIV already has minimized both of those about as far as we've ever seen any virus do it.
The best way a virus could prevent us form using this as an effective cure would be to cycle between periods of massive, almost indescriminate infection, and then all replicating using the dsRNA pathways at the same time, which would require some kind of chemical marker to signal the infected cells, and would require that our normal immune system would be unable to correctly deal with it. HIV does not do this, or at least, not in this way. HIV also selectively infects a body system that is difficult to live without, but rebuilds given the time, and can be compensated for by proper medical care (such as a clean room).
It's unlikely that viruses of any kind will ever improve their ability to deal with this treatment vector. It's also unlikely that all viruses will be completely shut down by this process, but all of them should be impeded fairly dramatically.

Knowledge on the evolution of viruses is nearly non existent. The selection of bacteria is well documented, but it's presumed that there was no evolution, but that drug resistant strains pre-dated the drugs, and the drugs killed the "normal" ones, allowing the resistant strains to grow unimpeded.

It's possible they wanted to get primacy fast and, knowing how good their work was, weren't concerned about the venue. Or perhaps the journal had favorable IP policy. Or maybe their methodology is crap but they "just know" it works, and this is a gambit to get primacy while they have time to nail down real results. Maybe they care a great deal about open access and know that with work like this they can get away with publishing anywhere. Or maybe it has a favorable submission deadline (primacy). Personally I'd publish on arXiv and then apply to a prestigious journal if I had results as good as they claim, but I don't know the customs of their field.
Or maybe they're crackpots. That said, LL is very well respected in scientific circles so I doubt they'd hire this guy if he weren't at least somewhat legit. The advocacy-style of writing and working in multiple fields is a bit unusual, but the very top scientists do tend to be active in more than one field (Feynman, for example).
93rd rule of Slashdot: No matter how obvious my sarcasm is, my comment will be taken seriously by someone.
I have learned to ignore anything about new medical discoveries until the drug in question is available from my local doctor, hospital or chemist.
Just because "drug x" does good things in rats or labs or even monkey/human trials doesn't mean its going to be available for normal people any time soon, if ever (think about all the instances where a promising drug came about and then never made it to market because of side effects)
So being the virus replicates in cells this med could eradicate infected cells. How does it penetrate the bone marrow is the real question. Since you can remove all the virus by preventing it from breed which is done in existing medicine it continues to exist in the bone marrow. One person has been cured by a complete bone marrow transplant but that is not simple, cheap, and it is far from painless. Would be interesting to know if this has any effect on the marrow as all.
--- Always remember. 99.36% of all statistics are inaccurate.
The current method to prevent this adaption is giving "cocktails" of several different kinds of drugs, that have different ways of killing viruses/bacteria. The idea being that a single bacteria in the presence of say, three different drugs, will have to randomly mutate a resistance to all three, on the same roll of the dice. The odds of this are a great deal lower, and help offset the short life cycle advantage. But lets face it, eventually it will happen, and when it does, if we don't find a way to eradicate it immediately, we're screwed, because now we have a bug in the wild that we have no way to kill.

Could a person survive if all cells containing a virus were killed off suddenly? Could a very small dose kill off some of the diseases while not overlaoding the person with dead cells?
I suppose the question is how quickly do the viruses kill off cells on their own. If it's essentially the same rate, then it's better to kill the cells with the drug.

Long version:
hand out antibiotics for colds that is. Plus we get another fun side effect of private medicine: people hoarding their antibiotics. Just about every poor person I know stops taking their antibiotics as soon as they feel better. Conventional wisdom says they just forgot. They didn't. They're saving them for the next time they (or their family) get sick because they can't afford the co pay to see a doctor & get a prescription (or they can't afford the time off, you can't take FMLA an infection). So as soon as they feel OK they stop taking the pills, and instead of the bacteria being wiped out they grow back stronger. Viva la private medicine!

There's also the slight side not that viruses with extremely high and fast fatality rates are actually selected against biologically because the host doesn't survive long enough to spread the infection.
A virus which behaved in this way would likely kill the host before the resulting clones of itself could be spread.
Sounds promising,but what if all of your cells are infected? or 80%? or 50%? or 20%? Could the cure be worse than the disease? “The good news is that we killed off the virus that was making you sick. The bad news is that we killed you too”.
The only nasty side effect that might take place is a huge leap in the evolution of viruses. The stuff that does survive will be some extremely nasty sci-fi shit, including, I wouldn't be surprised, viruses that "hold the body hostage" by infecting critical cells and the biological equivalent of polymorphic viruses.
Which will then zombify people.
Calling someone a "hater" only means you can not rationally rebut their argument.
Aren't these harmless viruses being used to transport treatments to target sites such as cancer? Maybe just proposed, I can't recall, but it seems like this drug could wipe out this form of treatment entirely. This could be a massive breakthrough drug, but it could also be the Mother of all Unintended Consequences. Genies out of the bottle very soon, I bet - at least for the very rich and powerful. Though it would be sublime karmic justice if they were the first to find out about the side effects.
If you have an endemic virus like, say, hepatitis, could it make your kidney explode? Even otherwise harmless viruses that are endemic to a critical system could cause fatal side effects.
Sometimes boldness is in fashion. Sometimes only the brave will be bold.
As long as the amount of cells is not too great, ....imagine if you had a viral infection on 50% of your cells....you would lose half your cells, and weight?
Have you never heard of drug trials? You have those first. If there are side effects, you eliminate if possible, mitigate where appropriate, and make a risk analysis.
