Antibody News and Research

RSS

An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

Scientists discover a catalytic antibody that degrades a known appetite stimulant

The antibody works against the gastric hormone ghrelin (pronounced "grell-in"), which has been linked to weight gain and fat storage through its metabolic actions. These findings point towards a potentially novel treatment for obesity that would interfere directly with the some of the biological mechanisms determining weight.

New technique sees into tissue at greater depth, resolution

By coupling a kicked-up version of microscopy with gold nanoparticles, investigators at Duke University have been able to peer so deeply into living tissue that they can see molecules interacting.

Respiratory syncytial virus may hide in the lungs, lead to asthma

Conventional wisdom has been that respiratory syncytial virus (RSV) - a common virus that causes infection in the lungs - comes and goes in children without any long lasting impact.

Rapid HIV testing in the emergency department boosts diagnoses, screening

One in every 50 people screened for a suspected sexually transmitted infection (STI) in the Emergency Department at Henry Ford Hospital was found to be infected with HIV using a rapid blood sample screening test.

High dose flu vaccine boosts immune response in elderly

Giving people age 65 and older a dose four times larger than the standard flu vaccine boosts the amount of antibodies in their blood to levels considered protective against the flu, more so than the standard flu vaccine does. The findings from a study of nearly 4,000 people were presented Oct. 26 at a national meeting on infectious diseases.

Sensitive ultrasound to spot early-stage cancer

European researchers have developed highly sensitive ultrasound equipment that can detect tiny quantities of reflective microbubbles engineered to stick to specific tumour cells. The technique should pick up tumours early and improve patients' chances of survival.

Scientists discover how a well-known protein repairs broken DNA ends

During the life cycle of our cells, a minefield of environmental and biological assaults can lead to double-stranded DNA breaks, the most lethal and dangerous form of DNA damage. Now, in research published online this week in Nature, Rockefeller University scientists reveal that when these breaks occur, a protein called 53BP1 helps repair them by mobilizing their dangly DNA ends - findings that uncover a previously unknown aspect of how double-stranded breaks can get fixed.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

Leukaemia drug may reverse multiple sclerosis brain damage

Scientists in Britain say a drug which was developed to treat leukaemia may also be a powerful new weapon against multiple sclerosis (MS).

Peregrine Pharmaceuticals reports on phase II trial of Bavituximab plus Docetaxel in advanced breast cancer

Peregrine Pharmaceuticals, Inc. has announced that updated preliminary data from the first stage of its Phase II trial evaluating bavituximab in combination with docetaxel showed that 10 of 14 (71%) evaluable breast cancer patients achieved an objective tumor response according to RECIST criteria.

Researchers identify novel type of antibody that potently inhibits HIV infection

A small antibody fragment that is highly effective in neutralizing the human immunodeficiency virus (HIV) by preventing the virus from entering cells has been identified by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

Hand, foot and mouth disease in China kills 3 children and sickens over 100 others

In the latest health scare in China three children have died from hand, foot and mouth disease and another 110 are sick - this is China's second outbreak of the virus this year in young children.

Biothera initiates second phase of metastatic colorectal cancer trial

Biothera has announced today it began dosing patients in the second arm of its metastatic colorectal cancer (mCRC) trial in August.

Shark antibodies show potential as lifesaver from cancer

Australian scientists have discovered a potentially potent weapon in the fight against cancer in antibodies taken from shark blood.

Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

Statins may prevent miscarriages in antiphospholipid syndrome

Hospital for Special Surgery researchers have found that statins may be able to prevent miscarriages in women who are suffering from pregnancy complications caused by antiphospholipid syndrome (APS), according to a study in mice.

Body's built-in weapon against HIV explained

Humans have a built-in weapon against HIV, but until recently no one knew how to unlock its potential.

Reason for body's response to borrelia discovered

Inside a cell it is so crowded that a certain protein from borrelia winds up being crunched. From having been like an oblong rugby football, it gets bent and then collapses into a lump. At this point a previously hidden part appears, known to trigger the formation of antibodies. This explains how Borrelia can be diagnosed, a process that was previously unknown.

New rapid test for rare leukemia

A new twist on a well-known cell sorting technique may allow physicians to diagnose rare leukemias in hours instead of weeks, according to a study by researchers at the Stanford University School of Medicine and UC-San Francisco.

Outlook for Crohn's disease improves due to new therapies

A study led by Mayo Clinic has found that infliximab (Remicade) administered alone (monotherapy) or in combination with azathioprine is a more effective treatment for patients with moderate to severe Crohn's disease than azathioprine alone.
