Treating leukemia...with HIV

Flipping through my new journals and trying to shake off a monster exam, I came across this amazing little article. The short version is that the New England Journal of Medicine has reported three patients successfully treated for Chronic Lymphoid Leukemia by injecting modified T-cells to knock down the B cells which were getting out of hand. (For simplicity: T-cells are immune cells which can "order" other cells to attack or force our own cells to commit suicide if they look "wrong" somehow. B cells - which are also immune cells - are the problem in CLL.) Two patients show complete remission, and a third showed considerable improvement.

Now, what specializes in modifying T-cells? HIV.

These doctors successfully modified HIV to create a vehicle for modifying T-cells. These modified T cells have not shown any toxic effects to patients in the past. Now, the experience of receiving this therapy looks pretty miserable, with whole body inflammation and reparable kidney injury. However, keep in mind 2 of the 3 patients had complete remission of leukemia.

The treatment is still in very early clinical trials. The authors speculate by altering the target for the T cells, this may become a new and powerful anti-cancer intervention. May. Phase 1 clinical trials are a long way off from common practice.

Warning: a decent background in the relevant topics might be necessary here.

And since everyone's managing to butcher this one while we're at it: here's MIT's official announcement on DRACO. http://www.ll.mit.edu/news/DRACO.html If you were asking about DNA viruses (my first question), MIT reports it works on adenoviridae, which are ds-DNA viruses. So yes - so far. It has not been tested on humans and clinical trials take a long time, so keep the champagne corked, but on ice.

OT: It does look like a very interesting way of treating leukemia and *touch wood* the results are looking quite promising.

Do you realize that THIS IS THE PREMISE for " I am Legend"?
DO YOU?
We will all die very soon.

You might die. I'm going to stalk Will Smith and leave hatemail at his safehouse, complaining about the way he ruined a classic novel.

If it works, I say it's cool beans. Sure it seems off-putting, but where would we be today if the person who came up with vaccination didn't say "Hey, maybe if we inject the patients with a little bit of the disease we're trying to prevent, they won't get sick!"

Yes, the ending of the book was much better.
On the other hand, ending a movie on such a bitter note is practically suicidal.

Haha, yeah that film was terrible, I haven't read the novel, but I saw the Vincent Price version, and thought it was way better.
OT: Wow, fingers crossed the trials go well.

Can't say I've ever seen the movie or read the book. If it's as bad an adaptation as "I, Robot" was however, then I can certainly understand your anger.

On-topic:
Very...unorthodox approach, I'll give them that.

I'm sure there will have to be future studies and tests to verify its usefulness, however.

I doubt it. If humanity hasn't managed to wipe it self out yet, we should be fine.

Stuff like that only happens in bad movies anyway.

Very nice, what will these crazy guys think of next? I just wish it was written more like a physics paper, you literally need to read about 10 lines to know everything in those.

In the discussion, they mention by switching the T-cell's targets, it could knock out other targets. It's in the usual conservative, calm tone of a science journal, so it sounds much more staid than it likely is.

"An important feature of this approach is that chimeric antigen receptor T cells can recognize tumor targets in an HLA-unrestricted manner, so that ?off-the-shelf? chimeric antigen receptors can be constructed for tumors with a wide variety of histologic features."

It sounds so dull, then the impact of what they said hits.

Click "Summary." The life sciences write abstracts, too.

Ahhhh so this is where the newest xkdc comic came from.

This is very interesting.

I hope it doesn't kill us all, heh.

It ain't for lack of trying I'll tell you that.
That's the point. If history was all puppies and rainbows up until this point, I'd be a little more concerned.
