Re-Engineering the Immune System
destinyland notes a microbiology professor describing "Immunity on Demand" (or "Immunity 2.0") and wonders whether we could genetically engineer all the antibodies we need. "...there's a good chance this system, or something like it, will actually be in place within decades. Caltech scientists have already engineered stem cells into B cells that produce HIV-fighting antibodies — and an NIH researcher engineered T cells that recognize tumors which has already had promising clinical trials again skin cancer. Our best hope may be to cut out the middleman. Rather than merely hoping that the vaccine will indirectly lead to the antibody an individual needs, imagine if we could genetically engineer these antibodies and make them available as needed?"
I for one welcome our new T cell Overlords
That we can't actually see a majority of diseases under a microscope, only the antibodies our bodies produce to fight it off. Has that part been a myth or have we merely technologically advanced past that?
I find it difficult for us to engineer an antibody to fight against something we haven't actually detected yet.

What's next, mechanical sperm?
At least let's hope we won't all end up like that guy in TFA's illustration. Looks like he's missing something.

Smarting up our immune system could turn to be a dumb idea, as a good part of us comes from virus
From TFA:
"We are not sure when this will all happen, but there’s a good chance it will, and perhaps the only question is when."
Hmmmmm . . .
Derya Unutmaz is an Associate Professor of Microbiology and Pathology at N.Y.U. School of Medicine. His current research is focused on understanding the function of human immune system.
I can tell him right now what the function of the human immune system is: to keep us from getting sick.
I'll take his grant money now.

All this is, of course, a delicate proposition. In some ways, an overactive immune system is as much of a risk as an underactive one: more than a million people worldwide a year die from collateral damage, like septic shock after bacterial infection, and inflammations that may ultimately induce chronic illness such as heart disease and perhaps even cancer.
This is just one possible outcome to programming new antibodies. I'd also be concerned with how the treatments mitigate any risk to shutting down our own immune system.
Hypothetical speculation: Say the treatment works well while you're taking regular doses of new Immunity 2.0 shots, but as soon as you can't afford to pay anymore, you're off the Immunity 2.0 shots. Well, it's been a while since your real immune system has had to work, so the next mutation of a virus comes along and 'oops'.
Most questions to risk will probably be found in lab research and trials, but it's still something to think about.

On a more serious note, this looks promising. I just hope we don't rush into this. The immune system runs a delicate balance, over response is nearly as dangerous as not enough. More research needed.
And then when a new disease comes along, our immune system is not properly trained, and we'll die.
Remember that the native Americans dies from illnesses which were relatively harmless for the Europeans, because they just didn't have all those illnesses there.
The Tao of math: The numbers you can count are not the real numbers.
I have to ask, b/c I don't know, but could this lead to lazy-, or even more inept immune systems?

I believe it should be "Re-Randomchanceing the immune system". Remember, something cannot be accidentally engineered. The summary writer is clearly in the pocket of Big I.D. /sarcasm
I judt got a nre Kinesis keybiartf so please excusr ant egregiou typos.
If the exogenous antibodies end up hitting the wrong cells in some people, there could be major problems. http://en.wikipedia.org/wiki/Autoimmunity Although I would expect that there would be some sort of pre-compatibility test to avoid major complications - but you can't realistically pre-test every cell type via biopsy.
If you think that the whack-jobs are ballistic about vaccines, wait they go off the rails for something like this!

So this is, like, vaccination 2.0. Is this a ploy to make vaccination more palatable to the freaks who think vaccines cause autism?

So we can't stop our poor dumb natural immune systems from attacking our own bodies, and we're just a few short years away from telling it what to do?
This sounds like the plot to Resident Evil.
Maybe I have been reading too much sci-fi lately but arent we closer to using nanotech as an immune system than using biological sources?

Wasn't there a Star Trek: TNG episode where they did this? Remember how everyone who wasn't engineered was dying?
Na, that'll never happen.

My ism, it's full of beliefs.
As someone who is allergic to nearly everything, I've taken a keen interest in the immune system.
I read something a while ago that said allergies and even things like nervous tics could be inherited from a blood transfusion. The idea is that along with the blood cells, you get the donor's white blood cells and antibodies, which then teach your own white blood cells how to make the antibodies, so you wind up with their allergies. It also said that some nervous system things like tics could also be inherited the same way. So it would seem we already have what the article is talking about.

Have you ever had a former Playboy Bunny in bed with you? I'd bet you'd go off the rails yourself to keep that going.
I'm a Biologist, and you're somewhat mistaken. Antibodies are so infinitesimally tiny that no light microscope can possibly see them, even compared to virii which are also fairly invisible under a microscope. Antibodies are easy to detect, however, because they have a constant region on their tail end, which we know how to identify. We have compounds that bind to that constant tail end and as a result tag the antibody and what it is binding to. It's like the antibody is a flag pole, and biologists can run a colorful flag up that pole when we want to see what piece of the ground the flag pole is attached to.
... which is good if we know what the antibody gene sequence is already, but difficult to figure out on our own. Nature is much more efficient (and cost effective) at that kind of thing. Once we let nature figure out what's best, we can just figure out the gene sequence from there to mass produce the antibody.
Engineering antibodies is a simple matter, it's the basis of immunization/vaccination. Traditionally, we give chopped up bacteria and virii to a patient and their immune system detects those and creates more antibodies to put into the blood stream to stave off future infection. With this approach, instead we feed immune cells in a Petri dish an antigen, and they produce antibodies specific to that antigen. We can separate out these antibodies and purify them because they have that constant tail region that we can detect. We can then inject these into a person and these antibodies will cling to whatever thing they've been engineered to detect and attract the native immune system to it.
We can also use genetic engineering tricks to produce en masse a single specific kind of antibody. The technology has been there for research labs for decades. Either method will work fairly similarly, but in my opinion the former seems "easier", because we let the cells sort out what specific antibody to make. If we genetically engineer immune cells, we have to know exactly what gene sequence will produce an antibody targetting exactly what we want targetted
... for 20 years. They were called "Navy doctors". They had all the latest technology, were extremely skilled, and... free. Of course, taxpayer dollars were paying them, but 1) total costs per person in the military are a hell of a lot less than the mess we have going on in the world of private health insurance, and 2) for the cost of something like the Iraq war, we could have provided health coverage for the entire country for like 15 years. So it's not like we can't afford it.
People who bitch about "socialized medicine" should try it some time.
Just don't make the new immunity cells so aggressive that they escape the body and start to eat the ink off of the all books in the world.
Oh, say does that Star-Spangled Banner entwine / The myrtle of Venus with Bacchus's vine?
Just guessing, mind, but maybe because prevention has advantages over cures?

I'm going to get whooshed for replying to that, but they do, except when diseases kill us faster than we can replenish our pool of Slashdotty sarcastic contrarian commenters.
I'll take some antibodies for meatloaf, that way Aunt Mary's "specialty" causes an immune response and I can claim to be allergic.

that are caused by the antibodies?

I'll leave it to your imagination how *that* turned out.

So it's the biologists who are screwing up this beautiful language! The enemy is within the gates!
To be fair, pertussis is an environmental bacterium and is pretty common in adults -- it doesn't need anti-vaxx (aka "pro-disease") loons to "bring [i] back."
Not so measles -- that's one we could actually send off to join smallpox in the annals of extinct pathogenic viruses. Or we could, if it weren't for people like Andrew Wakefield, who saw a chance to make some money by killing children in the UK. Thus we have babies too young to be vaccinated contracting measles in their paediatricians' waiting rooms because somebody took their unvaccinated darlings to Switzerland and when they came back the little darlings came down sick. http://www.jennymccarthybodycount.com/Jenny_McCarthy_Body_Count/Home.html

Otherwise, I don't know, why it would be posted on
Antibodies are only one and not the most important component of the immune reaction against viruses. T-cells are more important and less easy to... engineer, in this sense.
From what I remember in a cell bio class the B-Cells arn't programmed to make any specific antibody at first.(They're naive) When a new molecule shows up in the body some of those cells will edit their DNA to produce a specific antibody to that antigen. The ones that don't really match well die off and the ones that have editted their DNA to produce a good match live on to produce that antibody. If I remember right that process is kind of random so it takes quite a few naive B-Cells before one of them edits their DNA to make a good match. You could skip this step by having someone do the editting of the B-Cell by "hand" so to speak.
Did you know 80 to 90% of the moderators on slashdot wouldn't recognize a troll even if one dragged them under a bridge.
No biologist worth a dollar would ever say virii. It's viruses, damn it!!
Really? REALLY? I hope you don't buy into the redrick.
Read the damn bill. At no point would your doctor work for the government.
Agent of the government, what a bunch of crap.

I read this:

...and immediately went, "Yeah, and can you imagine how much that will cost you to get, let alone develop!" Let's pray we end these wars and get a public option in the U.S., because otherwise only the rich a-holes like Rush Limbaugh will survive with Keith Richards and the cockroaches!
It's all good until the 30-day trial period ends and they start showing popups...
One of the most interesting questions is how the immune system stores its information, and how we can erase it. If we can get the immune system to forget, we can cure allergies, arthritis, and many diseases caused by the immune system attacking one's own body.
Reminds me of the folks in The Culture, need to stay awake, relieve pain, fall asleep, be happy, be sad, need energy, be calm, get high, get really high, fight disease, etc, simply gland it - a neural implant ("lace") can release whatever chemical you want/need... wonderful stuff.
This nightmare is like GM crops, but ten times worse. It's one thing to put agriculture entirely in the hands of US corporations, but giving them control over our immune systems could be described as foolish. I think it would be simpler to cut out the middleman by committing suicide immediately.
From TFA:
Now, say again please, all after your oh-so-tired anti-government rants?
People with enhanced immune systems will run around cheerfully breathing pathogens on people who can't survive them. For once there is a strong and direct correlation between intelligence and chance of survival.
