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.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
