In an article appearing in a special issue of the Journal of Neuro-oncology, researchers at Cedars-Sinai Medical Centers Maxine Dunitz Neurosurgical Institute describe a complex cell-level process that allows malignant brain tumors to protect themselves by damaging the thymus, rapidly degrading the immune system. In a second article, Institute scientists identify a molecular mechanism that causes cell death of cancer-fighting lymphocytes as they infiltrate a brain tumor.
"We are dissecting and better understanding the mechanisms that enable tumors to evade destruction by the immune system. This gives us new tools in our fight against brain cancer, to essentially correct these deficits and further enhance the ability of the immune system, not only to detect but also to destroy brain tumors," said Keith L. Black, M.D., director of the Institute, Cedars-Sinais Division of Neurosurgery and the Comprehensive Brain Tumor Program.
In an animal study, researchers found that intracranial gliomas – aggressive brain tumors – damage the thymus, the gland responsible for the development and potency of the immune systems T cells. As the thymus shrinks and its normal structure becomes distorted, many of the thymocytes – the "immature" cells destined to become functional T cells potentially capable of destroying a variety of antigens – undergo a process that weakens and kills them.

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...
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...
