A team of biophysicists introduces a new method in atomic force microscopy that maps not only topographic features but also the specifics of biochemistry on biological molecules. The technique, which attaches antibodies to microscope tips, allows for precise location of proteins and has extensive applications in biotechnology.
A potential vaccine against cocaine addiction has been developed by attaching a cocaine derivative to a larger protein, inducing the immune system to create specific antibodies that attack the molecule. The research team hopes to begin human clinical trials by the end of the year.
A small radio-controlled aircraft equipped with a sensor developed at the Naval Research Laboratory (NRL) can monitor air for signs of biological weapons. The sensor uses fluorescent antibodies and optical fibers to detect biowar bacteria in water samples, allowing it to accumulate on probes over time.
Researchers discovered a gene segment that can 'jump' into foreign DNA, enabling vertebrates to create millions of different antibodies. This ability is crucial for the adaptive immune system, which relies on two lines of defense to detect and destroy invaders.
A new study from Johns Hopkins Medical Institutions found that 2.5% of healthcare workers already experience allergic reactions to rubber gloves, while 10% are sensitized but asymptomatic. The study aims to identify and prevent these potentially life-threatening allergies.
Researchers found that ewes' antibodies are passed to lambs through colostrum, making vaccination unnecessary until past the age of 6 weeks. This schedule change can save time and energy for farmers, with significant benefits for national agriculture.
Researchers at University of Maryland School of Medicine discovered that mature B cells can reactivate genetic machinery to produce novel antibodies in response to antigens. This antigen-driven process enables the immune system to adapt and respond more effectively to threats, potentially leading to faster recovery for cancer patients.
A new nasal flu vaccine has delivered good antibody responses and proven safe in children, offering a potential solution to stop the spread of the disease. The vaccine's effectiveness is now being analyzed in a larger study, which may lead to FDA approval starting in 1999.
Researchers at the University of Maryland School Medicine discovered that mature B cells can re-activate V(D)J recombination, allowing them to produce different antibodies and adapt to new antigens. This finding may help scientists better understand and control the immune system's response to infections.
Scientists have developed a new vaccine that uses an anti-idiotype antibody to stimulate the immune system and prevent Chlamydia trachomatis infections, which affect 700 million people worldwide. The vaccine was effective in animal experiments and may be available for humans with further development.
