Skin dendritic cells promote distinct and opposing antigen-specific responses

A new study reveals that just as different soldiers in the field have different jobs, subsets of a type of immune cell that polices the barriers of the body can promote unique and opposite immune responses against the same type of infection.

Microglia prune connections between neurons

Gardeners know that some trees require regular pruning: some of their branches have to be cut so that others can grow stronger. The same is true of the developing brain: cells called microglia prune the connections between neurons, shaping how the brain is wired, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, discovered.

Neogen develops new pathogen DNA detection method for E. coli strains

Neogen Corporation has announced the development of a breakthrough pathogen detection and identification technology that provides next day, DNA-specific test results for seven pathogenic E. coli strains. The technology could be adapted to target almost any bacterium of concern in almost any food sample type.

Microencapsulated cell transplant can help treat chronic illnesses more effectively

Chronic illnesses such as Alzheimer's or Parkinson's could be treated more effectively in the future, by means of the transplant of microencapsulated cells. The researcher from the University of the Basque Country (UPV/EHU) Dr Ainhoa Murua has presented a number of proposals for optimising this technique.

Scientists find distinct links between smoking during pregnancy and long-term harm for the child

Scientists now understand more about why being exposed to nicotine while you were a fetus will increase your risk of developing cardiovascular disease as an adult. "We have found distinct links between cigarette smoking or even using nicotine patches or gum and the long-term harm for the child," says Dr. DaLiao Xiao, a scientist who works at the Loma Linda University School of Medicine in California.

Cell biologists identify infection mechanism of adenoviruses

Mucosal epithelia do not have any receptors on the outer membrane for the absorption of viruses like hepatitis C, herpes, the adenovirus or polio, and are thus well-protected against pathogenic germs. However, certain viruses, such as the human immunodeficiency virus HIV, still manage to enter the body via the mucous membrane.

Researchers develop mouse model of rare human birth defect

A team of researchers from the University of Utah and Brigham Young University has developed a mouse model of focal dermal hypoplasia, a rare human birth defect that causes serious skin abnormalities and other medical problems. This animal model not only provides insight into studying the cause of focal dermal hypoplasia (FDH), but also offers a novel way to study a signaling pathway that is crucial for embryonic development.
