Using EMBL Hamburg s world-class beamline P12 at DESY s PETRA III synchrotron, a team of Slovenian researchers, in collaboration with EMBL s Svergun group, directed powerful X-ray beams at artificial proteins called coiled-coil origami. The proteins were designed to fold into a particular shape based on short modules that interact in pairs. By determining their molecular structure at the EMBL beamline, the researchers confirmed that the

Slovenian-developed vaccine to be designed as spray

Slovenian-developed vaccine to be designed as spray 4. February, 2021 Ljubljana – After developing a vaccine against Covid-19 last year, Slovenian researchers will focus on developing a technology to spray the vaccine into the nose or mouth, the head of the research team, Roman Jerala, has revealed for the STA. Jerala’s team developed the vaccine based on plasmid DNA, which contains the code for the virus proteins and triggers the production of virus proteins in human cells. These respond by creating anti-bodies and the protective T-cells. Trials have shown the vaccine producing a good immune response in mice and the antibodies neutralised the virus’s binding to an extent similar to other vaccines or the antibodies in patients who have recovered from Covid-19.
