to circumvent innate immunity was demonstrated (Cirl et al. 2008, Nature Medicine 14, 399-406). This involves a bacterial TIR domain-containing protein (Tcp) that is secreted by bacterial pathogens and inhibits Toll-like receptor (TLR) signalling. <p> Toll-like receptors have a central role in innate immunity. They recognise molecules from microbial pathogens and trigger an immune response through a signalling domain called TIR. Bacterial Tcps contain a TIR domain that mimics the TIR domain of Toll-like receptors. TLR signalling is interrupted when MyD88, a downstream component of TLR signalling, binds to the TIR domain of a bacterial Tcp instead of to the TIR domain of a Toll-like receptor. This way, secreted Tcps impair the release of cytokines and, subsequently, prevent an inflammatory response. <p> Our data show that bacterial Tcps or the TIR domains contained in Tcps can be used to modulate cytokine responses of innate immune cells as is desirable in the treatment of autoimmune diseases. Also, we provide a new anti-infective strategy that prevents secretion of Tcps.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
