The benefit of some cancer vaccines may be boosted by treating patients with an antibody that blocks a key protein on immune system T cells, according to a small, preliminary study led by researchers at Dana-Farber Cancer Institute and Brigham and Womens Hospital.
The study, to be published online on April 1 in the Early Edition of the Proceedings of the National Academy of Sciences (www.pnas.org), tested the effect of a single injection of the antibody MDX-CTLA4 in nine patients who had previously been treated with cancer vaccines for either metastatic melanoma or metastatic ovarian cancer. The result, in every patient who had received a particular kind of vaccine, was widespread death of cancer cells and an increase in the number of immune system cells within the tumors – evidence of a potent immune system attack.
"This study makes a strong case that combined immunotherapy – consisting of a vaccine and antibodies – can elicit a potent immune response to some types of tumors in patients," says the studys senior author, Glenn Dranoff, MD, of Dana-Farber.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
