Researchers at Cedars-Sinai’s Maxine Dunitz Neurosurgical Institute have described an immune-disruptive process driven by an enzyme that is overexpressed in the cells of many types of tumors, including malignant brain tumors called gliomas.
Blocking the enzyme’s expression in laboratory tests interrupted the series of cell-level events and led to the development of cells capable of launching an immune response. This finding supports the suggestion that medications attacking the enzyme may boost the immune system’s ability to recognize and target gliomas.
Results of the study on cyclooxygenase-2 (COX-2) appear in the October 1 issue of the Journal of Immunology. While COX-2 inhibition has been considered an attractive anti-cancer strategy, results of earlier studies on a variety of tumors have been inconsistent, puzzling and sometimes seemingly contradictory. Furthermore, because COX-2 is a complex enzyme that is affected by a variety of conditions and biochemical substances, many of its mechanisms and effects are not clearly understood.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
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...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
