Aluminum salts, or alum, have been injected into billions of people as an adjuvant to make vaccines more effective. No one knows, however, how they boost the immune response. In the March 19, 2013, issue of the Proceedings of the National Academy of Sciences researchers at National Jewish Health continue unraveling the mystery of adjuvants with a report that host DNA coats the alum adjuvant and induces two crucial cells to interact twice as long during the initial stimulation of the adaptive...

Sexually-transmitted diseases (STDs) enter the body through the mucosal epithelial cells and the ability to direct pathogen-clearing T-cells to points of infection may be the critical element in developing successful vaccines against these infections. In a study published in the Journal of Clinical Investigation, researchers led by John Schiller at the National Cancer Institute investigated the immune response to intravaginal immunization in mice infected with a form of the HPV virus carrying...

Lead scientist Professor Simon Cutting, from the School of Biological Sciences at Royal Holloway, has developed the jabs through the use of probiotic spores. He carried out fundamental studies into the biology of the bacterium Bacillus subtilis which attracted the attention of microbiologists due to its ability to form spores that can last millions of years before germinating under the appropriate environmental conditions. Professor Cutting says: "The mechanisms by which this process...

Infectious diseases–both old and new–continue to exact a devastating toll, causing some 13 million fatalities per year around the world. Vaccines remain the best line of defense against deadly pathogens and now Kathryn Sykes and Stephen Johnston, researchers at Arizona State University´s Biodesign Institute, along with co-author Michael McGuire from the University of Texas Southwestern Medical Center are using clever functional screening methods to attempt to speed new...

Perfluorinated compounds (PFCs), a synthetic class of chemicals which are found in a variety of everyday items, have been found in the human body decades after exposure and are believed to lead to earlier menopause and reduced fertility among women. Some of the products that PFCs are found in include non-stick frying pans, waterproof clothing and fast food wrappers. A new study is bringing to light clues that high exposure to PFCs in the womb or in childhood could also limit the protection...

Elevated exposures in children to perfluorinated compounds, which are widely used in manufacturing and food packaging, were associated with lower antibody responses to routine childhood immunizations, according to a study in the January 25 issue of JAMA. "Fluorine-substituted organic compounds have thousands of important industrial and manufacturing applications and occur widely in surfactants and repellants in food packaging and textile impregnation. The perfluorinated compounds (PFCs)...
