Scientists solve structure of a critical innate immune system protein

Scientists at The Scripps Research Institute have solved the structure of a crucial human immune system molecule called TLR3, an acronym for Toll-like receptor three. In an upcoming issue of the journal Science, the protein is described as a large horseshoe-shaped coil composed of 23 leucine-rich repeats (LRRs).

Technique called phylogenetic footprinting reveals new gene regulation system

By comparing 140 sequenced bacterial genomes, researchers have uncovered a system for regulating genes essential to bacterial replication - and they did it solely by computer keystrokes and mouse clicks.

Adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply

In a ground-breaking study, scientists at Children's Hospital of Pittsburgh have discovered that adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply, a previously unknown characteristic indicating that post-natal stem cells may play an important therapeutic role.

OHSU scientists say low FOXP3 means fewer disease-fighting cells, but new drug may help multiple sclerosis

Oregon Health & Science University researchers have measured genetic changes reflecting a drop in the body's ability to suppress inflammatory cells that attack nerve fibers and promote progression of multiple sclerosis.

Found! - mutant viruses that laid NSW low with gastro

New mutant viruses responsible for gastroenteritis outbreaks in New South Wales in recent times have been identified by research published in Emerging Infectious Diseases, a journal of the US Centers for Disease Control.

New research raises the possibility that the risk of developing arsenic-related disease is not the same for everybody

Children with a particular variation in the CYT19 gene metabolize arsenic differently than adults with the same genetic variant, according to a new research report. The findings have important implications for the safety of drinking water worldwide and the use of arsenic as a cancer drug.

Unknown factors make Scots people more prone to heart disease

The findings, which are published in the current edition of the Journal of Epidemiology and Community Health, conclude that although successful campaigns to get Scots to live a healthier lifestyle will reduce rates of heart disease in Scotland, they will not do much to narrow the gap in heart disease rates between Scotland and England.

Foxp2 gene plays an essential role in the development of social communication

The association between Foxp2 and language was first identified in a family in which half the members had severe speech and grammar impairments. Studies showed that all the affected family members had a mutation in the Foxp2 gene.

Genetic predisposition to lung cancer exists

First-degree relatives of black individuals with early-onset lung cancer have twice the risk of lung cancer than first-degree relatives of white individuals with early-onset lung cancer, according to a study in the June 22/29 issue of JAMA.

No increase in anxiety or depression when children of people with Alzheimer's get genetic testing

Adult children of people with Alzheimer’s disease were satisfied and unharmed by the experience of genetic risk assessment, even when results suggested they might be at risk, according to a new study presented at the first Alzheimer’s Association’s International Conference on the Prevention of Dementia.

Early embryos with abnormal chromosomes are capable of returning to normal when grown in culture in the laboratory

While such embryos are not capable of developing into normal foetuses if implanted in a woman's womb, the discovery has important implications for stem cell production, especially in countries where the creation of embryos for stem cell research is discouraged or even banned.

Women who have a special genetic profile can conceive spontaneously after the age of 45 years

Dr. Neri Laufer, from the Hadassah University Hospital, Jerusalem, Israel, told the conference that his team's work to identify a specific gene expression profile linked to later fertility would help understanding of the ageing process, as well as enabling the development of better treatments for infertility in older patients.
