Researchers have created a new vaccine that can prevent life-threatening infections caused by Staphylococcus aureus bacteria, which are resistant to common antibiotics. The vaccine targets the bacteria's capsular polysaccharides and has shown significant efficacy in reducing bacteremia in hemodialysis patients.
Researchers from Brown University and Seattle Biomedical Research Institute found high antibody levels against liver stage antigens (LSAs) correlate with malaria resistance. The study suggests LSAs may stimulate an immune response that protects against infection, paving the way for new malaria vaccine strategies.
Researchers found a virus similar to HEV in rats in Los Angeles, which may contribute to the high rates of HEV antibodies in some inner city areas. The study suggests that infected rats could be a source of exposure for humans and highlights the need for further testing.
Researchers found that bovine thrombin causes an immune response similar to lupus in mice and can lead to post-operative complications. Bovine thrombin is a potent enzyme used in surgical procedures, but its use should be restricted to life-saving surgeries due to the risk of autoimmune responses.
Researchers found a link between higher levels of antibodies neutralizing toxins and better kidney function in patients after heart surgery. The study suggests potential interventions to protect kidneys from endotoxins released by bacteria during surgery.
Researchers found that antibodies can convert oxygen into hydrogen peroxide, a previously unknown mechanism that could enhance their killing power and contribute to autoimmune diseases like lupus. This discovery opens up exciting possibilities for new antibody-mediated therapies for bacterial, viral, and cancer treatments.
Researchers at UC Berkeley have developed a sensitive assay for detecting proteins associated with prostate cancer, which could lead to fast screening and molecular profiling for various diseases. The technique uses micromachined cantilevers that can detect levels of protein markers 20 times lower than the clinically relevant threshold.
Researchers create antibody Fab D18, which blocks prion propagation and clears infectious prions from cell cultures. This breakthrough provides a potential therapeutic target for a human drug to cure established infection.
Vancouver is facing a high risk of an hepatitis A outbreak due to past infections among street youth, injection drug users, and men who have sex with men. The Canadian Medical Association Journal report highlights the need for vaccination programs to protect these groups.
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.
