Yeast is a microscopic, single-celled organism that can be seen in the figure below. This tiny and basic thing is everywhere, mostly in the air but also in our own soil and even at arm's length - water. Yeast is super powerful in science and medicine because scientists use it to make important things such as vaccines, which help keep us healthy. They do this in part through the fascinating creation of something known as VLPs.
VLP: virus-like particles The ones that the U.S. has cleared are little constructions of what appear to be viruses but don't actually make you sick. So, they lack all the components that make us ill or infectious. VLPs are a way for scientists to train our immune system on how to fend off actual viruses. That is where the use of a virus looking concoction comes - to help our immune system practice how they would recognize and attack, without really being infected (hence can infect its host chain)!
One yeast, very good at producing quality VLPs. They have a unique property to generate set of proteins in fast rate which can assemble together for VLPs. By altering yeast cells, scientists can make them express VLPs that appear virtually indistinguishable from the outside of live viruses. This is a very useful attribute because we can teach our immune system how to destroy the viruses, therefore making them extremely effective. That way when our body encounters a real virus, it can draw on that information to fight the invader.
The yeast cells receives new, exogenous genes encoding the viral proteins necessary for forming VLPs. These genes are kind of like a recipe for the yeast. The cells receive these commands and produce the proteins, which are then secreted into the medium. The proteins begin to auto-assemble and VLPs are forming. Scientists then harvest the VLPs produced by the yeast, purify them and incorporate them into vaccines to help protect people against diseases.
While can make VLPs, yeast fermentationcan also help produce the other critical proteins and enzymes we need in our bodies. To name just one, insulin - an essential treatment for those afflicted with diabetes - is now produced through yeast fermentation. If anything, it is just a demonstration of what yeast can be used for in such wide ranging projects and the potential uses it has to offer many industries.
One of the hardest parts about making VLPs, Clover said, is ensuring that they remain both high-quality and produced at exactly the same amounts each time. This requires each batch of VLPs to be consistent so they are efficacious in vaccines. Indeed, yeast fermentation technology has come a long way in the last several years. Modifications of the process by scientists to boost production VLPs are many. Special facilities that have the right growing conditions for yeast to flourish and produce large quantities of VLPs are erected.
VLPs are continually being produced by yeast fermentation with further refinements in the pipeline as scientists work to improve on perfection. They study optimal yeast conditions, test various types of yeasts, and then tweak the genes that code for viral proteins. With these advancements, VLPs will be produced in a more efficient and cost-effective manner. This allows more people around the world to benefit from these vaccines and treatments.
