Scientists find that lipocalin 2 protein disables macrophages in bacterial pneumonia

Macrophages, also known as scavenger cells, play an important role in defending against bacteria and pathogens by activating inflammatory processes. In cases of lung inflammation (pneumonia) caused by pneumococcal bacteria, this important immune response function is hampered and blocked by the protein lipocalin 2.

Structural properties have changed across bacterial families without putting limits on antibiotic resistance

Antibiotic-resistant bacteria have been emerging at an alarming rate. In some of the scariest of these pathogens, the mechanism responsible for the bacteria's ability to defeat antibiotics is a complex protein molecule embedded in the bacterial cell wall -- the enzyme β-lactamase.

Researchers visualize live cell-to-cell communication pathways in bacteria

Most bacteria are able to communicate with each other by secreting signaling molecules. Once the concentration of signals has reached a critical density (-the Quorum), the bacteria are able to coordinate their behavior

Scientists take important step toward pharmacologic development of treatment for fatal brain disorders

A team of researchers from Case Western Reserve University School of Medicine have identified a mechanism that can prevent the normal prion protein from changing its molecular shape into the abnormal form responsible for neurodegenerative diseases. This finding, published in the July 18 issue of Cell Reports, offers new hope in the battle against a foe that until now has always proved fatal.

Human filariasis research: an interview with Professor Mark Taylor, Liverpool School of Tropical Medicine

Filariasis refers to a group of diseases caused by parasitic worms, which are transmitted by blood feeding insects. Two species infect the lymphatic and blood systems causing lymphatic filariasis, which in some people can lead to gross swelling of the limbs and 'elephantiasis'.

Social media and DNA fingerprinting played important role in alerting strep outbreak

Facebook posts helped alert public health officials to a strep throat outbreak among a high school dance team in 2012, and DNA fingerprinting led investigators to pasta prepared by a previously ill parent as the likely source.

New class of WBCs in human lung and gut tissues play a critical role against fungal infections

Scientists at A*STAR's Singapore Immunology Network (SIgN) have discovered a new class of white blood cells in human lung and gut tissues that play a critical role as the first line of defence against harmful fungal and bacterial infections.

Modified forms of bisphenol A found to alter hormone signaling in new, disturbing ways

For years, scientists have been worried about bisphenol A. The chemical is known as an "endocrine disruptor," a substance that interferes with the body's hormone signaling system, and it's found in everything from plastic drink bottles to the linings of food and drink cans to the thermal paper used for cash register receipts - not to mention the urine of 92.6 percent of Americans over the age of six.

Health benefits of short-chain fructooliogosaccharides

A new presentation today at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Expo in Chicago- focused on the health benefits of short-chain fructooliogosaccharides (scFOS), which are low-calorie, non-digestible carbohydrates that can improve food taste and texture while aiding immunity, bone health and the growth and balance of important bacteria in the digestive track.

Study shows environmental conditions have stronger influence on human microbiome

Environmental conditions have a much stronger influence on the mix of microbes living in various parts of your body than does competition between species. Instead of excluding each other, microbes that fiercely compete for similar resources are more likely to cohabit the same individual.
