These antibodies then mobilise the body's immune defences to attack and destroy the cells.
The company believes that these antibodies might one day be useful for treating cocaine overdoses.
Because the proteins surrounding elephant ova are similar to those from pigs, these antibodies attack the elephant ova, too.
She said harnessing these antibodies "could be a big deal" and there was "even talk about mass-producing antibodies and infusing people with them".
And for the first few weeks, these antibodies are successful, eliminating all but a few viruses that remain hidden away from the body's surveillance systems.
The challenge will be to push the body to pump out these antibodies rather than the more specific ones aimed at the ever-changing portions of HIV.
In addition, these antibodies can bind to and destroy healthy cells as well as HIV-infected ones, making them a potentially useful but unpredictable partner in fighting the virus.
"Now we have a picture of how these antibodies developed, so what we are doing is figuring out how to use them to make a vaccine, " says Haynes.
To test the effectiveness of these antibodies, the two researchers injected cells that belonged to one genetic population of mice into the leg muscles of mice from a different genetic population.
It turns out that most infected people do produce these antibodies, but HIV distracts the immune system into crowding them out with all the subsequent iterations they convince the body to make against the mutating virus.
But most attempts to convince the body to churn out these antibodies haven't been successful, primarily because the antibodies take on an unusual shape that marks them for destruction by the very immune system that generated them.
In theory that should make it easier to produce a vaccine which could stimulate the body to start producing these key antibodies.
If a molecule of the type the sensor is designed to detect sticks to one of these anchored antibodies, it can also stick to an antibody on one of the free-floating outer channels.
Researchers believe these new antibodies promote the production of a mysterious class of immune system cells called regulatory T cells that act as peacekeepers to ensure the rest of the immune system's soldiers remain under control.
In early-stage clinical trials, these drugs, as well as injectible antibodies developed by Abgenix (nyse: ABGX - news - people ) and ImClone (nyse: IMCL - news - people ), seemed to cause tumor growth to slow or shrink.
Offering the jab to pregnant women between 28-38 weeks gestation will boost maternal antibodies against whooping cough and allow these to be passed to the unborn baby, giving them protection in the crucial first weeks of life.
HGS, gets human antibodies out of the mice and, if these prove useful in a test tube, makes human monoclonals directly from XenoMouse for further testing as potential drugs.
However, the injected cells remained healthy in animals that were treated with the antibodies, and three months after drug treatment had ended these transplanted cells were even found to be replicating in some of the animals.
Researchers found that the first round of broadly neutralizing antibodies generally appeared about 14 weeks after infection, and these were better able to bind to portions of HIV that the virus doesn't change as quickly or as frequently.
Sanofi has increased the proportion of its pipeline that are biologics proteins like antibodies and insulin from 17% to 48%, and these have lower failure rates than traditional pills.
FORBES: Sanofi CEO: It's Not A Plavix Hangover, We're Investing In Launching New Drugs
These viral stalwarts then mutate to escape detection and start to flourish, expanding until new antibodies are generated to dispatch them.
Such broadly neutralizing antibodies are the holy grail of AIDS vaccine researchers, who hope to corral these agents in an immunization that can protect against infection.
Research into these biologic antibody-based approaches is at an earlier stage than the testing of antagonist drugs, but antibodies eventually might be able to block CGRP action regularly so that migraines don't ever begin.
