Scientists discover new mechanism regulating the immune response

01.07.2013
Scientists at an Academy of Finland Centre of Excellence have discovered a new mechanism regulating the immune response that can leave a person susceptible to autoimmune diseases.

A fresh study by Turku Centre for Biotechnology and Aalto University in Finland is the first to report a new mechanism that regulates specification of lymphocytes, the white blood cells pivotal to immune response.

By combining state-of-the art techniques, next-generation deep sequencing and computational data mining, the researchers discovered new epigenetic factors regulating lymphocyte function. Regulatory regions of the genes studied displayed variations (single nucleotide polymorphisms or SNPs) that have been associated with predisposition to autoimmune diseases such as type1 diabetes, rheumatoid arthritis and inflammatory bowel disease. These discoveries provide new insight into and basis for the study of emergent mechanisms of immune-mediated diseases.

Immune-mediated diseases such as type 1 diabetes, rheumatoid arthritis, asthma and allergies result from abnormal immune response. T lymphocytes that orchestrate the immune response can differentiate into functionally distinct lineages to combat infection and disease. The correct response to cytokines and a controlled balance of T lymphocyte populations are critical for the immune system and for the avoidance of autoimmune disorders.

The study was published in Immunity, a distinguished international scientific journal.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
