The largest genetic study of atopic dermatitis ever performed permitted a team of international researchers to identify ten previously unknown genetic variations that contribute to the development of the condition. The researchers also found evidence of genetic overlap between atopic dermatitis and other illnesses, including inflammatory bowel disease. The results was published in Nature Genetics online on October 19.
Atopic dermatitis, a type of eczema, afflicts approximately one out of every five children and one out of every twelve adults. Though knowledge of the genome is crucial to assessing the likelihood that an individual will develop atopic dermatitis, most genes responsible for the condition have not yet been discovered.
A study of 377,000 sheds light on the role played by the genome in eczema

The team of international researchers that conducted the largest genetic study of atopic dermatitis to this point pooled data obtained from 377,000 subjects in 40 different projects around the world.
31 currently known
“We identified ten new genetic variations, making a total of 31 that are currently known to be associated with atopic dermatitis,” says Bo Jacobsson, a professor at Sahlgrenska Academy who was a member of the team. “Of particular interest is that each of the new ones has a role to play in regulation of the immune system.”
The researchers found evidence of genetic overlap between atopic dermatitis and other illnesses, including inflammatory bowel disease.
“While the new variations contribute in only a small way to the risk of developing atopic dermatitis, knowing about them will raise our awareness about the mechanisms of the various diseases,” Professor Jacobsson says. “Our ultimate hope is that additional treatment methods will emerge as a result.”
Although the importance of genetic factors in the pathogenesis of atopic dermatitis had already been established, the sheer size of this study allowed researchers to fine tune their understanding and obtain more information about the ways that autoimmune mechanisms run amok as the disease develops.
A total of 21,399 cases of European, African, Japanese and Latino ancestry were first compared in 22 different studies with 95,464 controls. The findings were then replicated in 18 studies of 32,059 cases and 228,628 controls.
“Multi-ancestry genome-wide association study of 21,000 cases and 95,000 controls identifies new risk loci for atopic dermatitis” was published in Nature Genetics online on October 19.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
