How Llamas Could Help Us Fight the Flu (pbs.org)
An anonymous reader quotes a report from PBS: Researchers now think they're on the path to a new kind of flu protection -- one that might last longer and work against all types of influenza viruses. The source of their new defense: llamas. These furry South American mammals produce special antibodies -- molecules that mark foreign invaders in our bodies for destruction -- that can identify a huge range of elusive influenza viruses. A new study used these antibodies to target multiple strains of influenza at once, a technique that could lead to more effective flu prevention. These antibodies can survive without refrigeration for longer, which could reduce the cost and complexity of flu treatment.
The researchers behind Thursday's study fused four different single-domain antibodies into one larger molecule, held together with a human protein as a scaffold. When they injected this hybrid into mice, the antibodies kept the animals safe from a wide variety of influenza type A and type B viruses -- the two most common assailants in America's annual flu epidemic. This hybrid seemed to successfully target each of the five flu strains they tested. When the researchers injected mice with their hybrid antibody, it protected the mice from lethal doses of the flu. But the paper also explored another route of delivery: gene therapy. The researchers used a benign virus -- dubbed AAV -- to embed the genetic blueprint of the llama antibodies directly into mouse cells. This procedure allowed the mice to produce the antibodies on their own.

Found the Drama Llama!
now the llama is whipping flu's ass!
This is just a prank by the guys who made SimCity 2000. Go build a stadium if you don't believe me.
It would also be helpful if:
- You transported food by llama to the sick
- You transported medicine by llama to the needy
- You transported people to the hospital by llama when they can't walk
- You transported the llama to the dinner table when it falls off a cliff

When we talk about 'smart transportation,' it is more than moving cargo from A to B. - Soren Skou
I know this sounds exotic and exciting, but the llama angle on this story is basic biotechnology. Llamas (and several other species) make simpler and smaller antibodies than typical mammals. This makes them much easier to work with, sequence, etc. When making a custom antibody, it's not unusual to choose a llama as your "antibody development tool."
There are llama farms near biotech hubs that do nothing but repeatedly inject llamas with small doses of some protein or molecule and sell the blood (packed with antibodies) back to the pharma and biotech companies.
The actual neat part of this story is the (slow, but steady) development of a universal influenza vaccine.
... now we gonna get Llama Flu
Ain't science fun?
Llamas have become popular as emotional support animals. I'm still getting used to seeing them in the grocery stores, though.
One of the unique benefits associated with creating the vaccine in llamas is they can spit it directly into people's faces instead of requiring pesky injections!
Sharing germs to keep their little nanobodies up to date.
"The researchers used a benign virus -- dubbed AAV -- to embed the genetic blueprint of the llama antibodies..."
I saw this movie. It was called, "I Am Legend."
One of the research llamas is named Dalai.
It must have been something you assimilated. . . .
Iâ(TM)m a lama again! Wait...
Yes, yawn, camelid antibodies. To me the big deal here is they are doing Gene therapy to get the host to make them. Now that's kinda edgy dangerous territory.
Some drink at the fountain of knowledge. Others just gargle.
Antibodies, antibodies, antibodies, antibodies!
Sorry...
Corruption is convincing someone that the selfless ideal is the same as their selfish ideal.
But your neck will grow really long (not to mention hairy), and you’ll have a constant, irresistible urge to spit all the time.

You can keep this shit. No way.
Enjoy your smallpox.
Seriously, the llamas are not "helping" us do shit. What, did some science guys say, hey llama, can you help us out here and the llama was like.. no problem man.
It is "how we can use llamas to help us fight the flu".
Pedantic, I know.
Just don't let a møøse bite your sister!
Not even able to quote the sources in the original (superior, of course!) language... what a shame.
If the Llamas ate all our hands, we couldn't get infected via unwashed hands! Brilliant!
Crivens! I kicked meself in me own heid!
..don't seem so PC now, do they?

Bracing for a three el flame war.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
Napoleon Dynamite for this discovery. Turns out feeding Tina all that ham was actually a scientific study...
Enjoy your Tuskegee syphilis.
Llamas are LARGER than frogs.....
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
New Marvel Superhero. Geneticlly spliced with Llama DNA by a Mad Scientist in Peru......
Created to fight disease and drama on the internet!
Given that my first name is "Carl," I approve of this discovery.
I do wear hats, but not a green one.
