Immune responses to prevent or delay the spread of melanoma, a deadly form of skin cancer, are more likely to prolong survival in patients if their immune cells carry a special kind of marker on the surface, according to a team of researchers at the University of Virginia Health System. The finding is published in the November 1 issue of the journal Cancer Research, found on the web at http://cancerres.aacrjournals.org/
The researchers correlated the presence or absence of the protein with survival in 52 U.Va. patients with advanced metastatic melanoma who were enrolled in experimental clinical trials over the last decade. They found that survival increased by fifty percent in patients whose T lymphocytes (the immune cells that kill tumors) carried a particular protein, or chemokine receptor, called CXCR3.
Increased survival was seen in patients with Stage III metastatic melanoma, but no increased survival was noticed in patients with Stage IV, stressing the importance of early detection and treatment for melanoma. "As immunologists continue to target the spread of cancer, this research gives scientists new clues to help develop vaccines that both ’turn-on’ cancer-killing immune cells, as well as instruct the cells on how to find tumors. Together, that will improve the efficacy of vaccines against cancer in the future," said the study’s principal investigator David W. Mullins, PhD, assistant professor of microbiology and a researcher in the Human Immune Therapy Center (HITC) at the U.Va. Health System.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
