Mouse brain cells rapidly recover after Alzheimer's plaques are cleared

...hool of Medicine in St. Louisinjected mice with an antibody for a key component of brain plaques,the amyloid beta (Abeta) peptide. In areas of the brain whereantibodies cleared plaques, many of the swellings previously observedon nerve cell branches rapidly disappeared. "Theseswellings represent structural d...

...ablished safety and the ability to elicit a strong antibody response in humans. "Since all the media used here are chemically stable and commercially available, the process can be easily scaled up for commercial manufacture," says Wang. "New FluBlok vaccines can be developed quickly and safely to address lat...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

...lop ways to induce that first line of polyspecific antibody defense during vaccination, if these antibodies are not harmful to those being vaccinated," Haynes said. "We now have a window into how to study HIV vaccines from the host side of the problem," he said. Collaborators on the study include Judith Fle...

Two are better than one

...t's more than three times as effective as a single antibody in inhibiting HER2 signaling. "Understanding how HER receptor degradation works could enhance weak therapeutic efficacy, as well as provide ways to sensitize patients to overcome inherent or acquired resistance to cancer treatment," says Yarden. Pr...

NIAID begins clinical trial of West Nile virus vaccine

...he DNA vaccine's exploitation of both cellular and antibody immunity offers a potentially potent defense against West Nile virus," says Barney Graham, M.D., Ph.D., chief of the VRC's Clinical Trials Core Laboratory. Adds Dr. Graham, "In our experience in clinical trials, DNA vaccines generally cause few side ...

Wake Forest scientists find new combination vaccine effective against plague

... protein termed flagellin is added to the vaccine, antibody levels against the plague bacteria are 500,000 times higher. "Flagellin can function as an effective adjuvant, making a vaccine that protects against the most dangerous form of the plague ?pneumonic plague," reported Mizel, professor and chairman of...

From 9 % in the two large cities of Gabon, antibody prevalence goes up to 25 % in the untouched villages of the epidemic area, reaching 32 % in the villages where human cases have been attributed to an infected-animal source. These domestic animals could therefore become infected and excrete virus ove...

Active Vaccine Prevents Mice From Developing Prion Disease

...mmune response to the gut and mainly stimulates an antibody response, says Dr. Wisniewski. "By giving our vaccine orally, we're stimulating an immune response mainly in the digestive tract," he explains. "Thus, harmful prions in contaminated food will be destroyed in the gut and will not reach other organs in...

New vaccine means bye-bye to bacteria in the lung

...or. Immunization of mice with this vaccine induced antibody production and protected the mice from exposure to a deadly dose of the bacteria. Importantly, the mice could be repeatedly given the vaccine and the immune response against P. aeruginosa was boosted. Usually, adenovirus vectors do not allow for repe...
