Published in the current edition of Viral Immunology, these findings may point the way toward developing new and more effective vaccines against diseases like influenza or HIV and enhance new developments in immunology.
The study suggests that scientists can boost the body’s resistance and fend off successive viral infections by taking components of the virus and indirectly activating specific populations of killer T cells – the body’s virus-killing cells. The virus components are introduced through a process known as “cross priming” whereby virus molecules are engulfed by immune cells to activate killer T cells.
“With this mechanism in mind, we can develop better tools to make more successful and effective vaccines,” says Sam Basta, Queen’s professor of Microbiology and Immunology, and the principal investigator of the study. The other members of the research team are master’s students Attiya Alatery and Erin Dunbar.
The researchers hope to build on their findings by next studying which immune cells do a better job of protecting the body while using this mechanism.“The answer to this question is like having the Holy Grail of immunotherapy and vaccine design within our grasp,” says Dr. Basta.
The study was funded by Natural Sciences and Engineering Research Council of Canada and the Franklin Bracken Fellowship program.

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
