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.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
