#Studies of cow antibodies help scientists understand how our own bodies workunderstanding how antibodies work is important for designing new vaccines to fight infectious diseases
of researchers from The Scripps Research Institute in La jolla Calif. In San francisco Ekiert will explain how the immune systems of cows are used to understand the diversity of antibodies
Second the unique structure of these cow antibodies may be suited particularly well for recognizing certain kinds of antigens
and may be useful for antibody based therapies or diagnostics explained Ekiert. It turns out that cows make a very unusual kind of antibody different from anything scientists have seen ever before
and their antibodies are diversified by a surprising mechanism. Antibody diversity is particularly important because our ability to recognize
and neutralize a wide range of pathogens directly depends on the diversity of our antibody repertoire--the more different kinds of antibodies we have in our bodies the more different kinds of targets we can block said Ekiert.
Previous work described an unusual subset of antibodies in cows that had exceptionally long loops
but no one knew what they looked like or how they were being generated. A collaborative effort including Ekiert from Ian Wilson's lab at Scripps Research as well as Feng Wang from Peter Schultz's lab
and Vaughn Smider used x-ray crystallography to determine the ball and chain structure of the bovine antibodies
while deep sequencing helped researchers study the function and generation of these antibodies. The next steps in realizing the potential of this research are to determine just how these antibodies recognize their target antigen molecules and bind to them.
In addition to the obvious benefit of helping us understand the human immune system the research may benefit the large-scale raising of cattle an important segment of the U s. economy as new vaccines can be developed to protect farm animals from common cattle diseases.
Ekiert concludes Once we understand these mechanisms it is possible that bovine antibodies might be able to recognize some antigens that more conventional antibodies cannot
and would help to bind inhibit and activate targets that have thus far been intractable for antibody-based therapies.

Further the results showed that adorning APEC with anti-ECP antibodies--a process known as opsonization--could significantly inhibit bacterial adherence.
because if it can be confirmed that epsilon toxin is indeed a trigger of MS development of a neutralizing antibody
According to this the usage of hypoallergenic molecules (with lower ability of binding antibodies) but with the ability to stimulate the immune system would be a useful tool for immunotherapy.
As an alternative this allergy research has defined the regions of this allergenic protein that is involved in the antibody binding and the stimulation of the immune system cells.
These variants are the result of modifying epitopes (regions of binding antibodies) of this protein
presented lower capacity for binding antibodies. Also it maintained its ability to stimulate immune system cells (lymphocytes) of the patients allergic to peach during the in vitro trials.
will test the safety of the plant-produced antibody designed to stop transmission of HIV when applied directly to the vaginal cavity.
The active ingredient is called an antibody P2g12 â oe it recognizes proteins on the surface of HIV to block infection.
More specifically, it's a monoclonal antibody made from immune cells for one specific role. It was discovered by private Austrian biotech Polymun.
and highly purified antibodies are extracted. The process yields 5 grams of purified antibody from 250 kg of tobacco.
Advocates of this emerging field â oe called molecular farming â oe say that protein drugs could be made more efficiently and cheaply inside GM CROPS,
The biotech medicine is the first plant-produced antibody to be greenlit for clinical testing by Britain's Medicines and Healthcare products Agency.
