Web19 de abr. de 2002 · Viral Recruitment of Ribosomes. The unique features of the eukaryotic ribosome, located primarily on its outer solvent-exposed surfaces, are prime targets for interaction with regulatory factors. These surfaces can also be exploited by viruses for ribosome recruitment during host cell infection. WebOur ribosomes know what to do, but we still have a lot to learn A handful of companies are developing mRNA vaccines in the fight against COVID-19. At the time of writing this article, two vaccines have made it through preclinical trials and early-phase safety trials, and are now undergoing large-scale efficacy studies in tens of thousands of people.
