The success with kidney transplant patients is given particularly noteworthy the number of very ill people who come to the medical center with a high probability of rejecting a donor organ because of high amounts of antibodies in their blood.
Antibodies are protein molecules that are an important part of the body's immune defense system but can cause rejection of a transplanted organ.
Stanley C. Jordan MD director of Kidney Transplantation and Transplant Immunology is a prominent pioneer in designing treatment approaches that have significantly reduce the amount of antibodies thereby reducing the risk of organ rejection.
Cary Mitchell professor of horticulture said the technique could be particularly useful for growing transgenic crops to produce high-value medicinal products such as antibodies for the budding plant-derived industrial and pharmaceutical compounds industry.
which seeks to identify the defect in T-cell activation--an immune response used to fight foreign antigens--during microgravity exposure.
The therapeutics known as monoclonal antibodies (MABS) and their derivatives were shown to neutralize and protect mice against a lethal dose challenge of West Nile virus--even as late as 4 days after the initial infection.
However this antibody was not to be able to accumulate at high levels in the brain.
One approach to tackle this challenge is to program into the therapeutic antibodies the capability of binding to receptors that can help the MABS to cross into the brain.
The tetravalent MABS design will offer the researchers greater flexibility toward selection of disease tissue and antigen targets.
This drug reduces activity of the body's Ige molecules the antibodies involved in allergic responses
bactericides plant defense response and plant nutrients he said. We are trying to alleviate the disease symptoms on tubers
His efforts to control the pathogen using foliar applications of a bactericide has had good results for two years
Bactericides for potatoes are labeled only for seed treatments although foliar applications in the field are allowed on some tree fruits crops.
If we can include bactericides in a program that can minimize insecticide use then this could be integrated part of an disease management approach he said.
#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.
This finding suggests that ECP could be considered as a potential antigen for vaccines for both human and poultry infections.
because if it can be confirmed that epsilon toxin is indeed a trigger of MS development of a neutralizing antibody
and designed to boost the immune system's natural ability to protect the body against foreign invaders called antigens.
Dendritic cells are the immune system's most powerful antigen-presenting cells--those responsible for helping the immune system recognize invaders.
By being loaded with specific protein fragments of CD133 the dendritic cells become trained to recognize the antigen as a target
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

In the laboratory they cultured the proteins with dendritic cells the immune system's most powerful antigen-presenting cells

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.
