Cowpea Chlorotic Mottle Virus
CCMV is the abbreviation of Cowpea Chlorotic Mottle Virus, and is a well studied black eyed pea infecting virus. It is a virus in the family Bromoviridae, and it is one of the most studied plant viruses. As from the discovery of the virus in 1967, it was an interesting virus due to the easy cultivation and harvesting procedures involved. Interest in this virus is especially in the ability to disassemble the virus, remove the content and refold the empty particle simply by altering the pH. This makes this virus one of the first and best studied Virus Like Particle.
VLP
The idea of disassembly and reassembly of CCMV into VLPs did not stop by the formation of empty particles. Little inorganic crystals and proteins were also able to be captured into the shell. The production of these VLPs can also be integrated into a synthetic biology approach. Expression of only the coat protein in ‘’Escherichia coli’’ or yeast could also provide the coat proteins that are able to assemble and reassemble when playing with the pH. This way however opened the interest of a whole new kind of applications for these VLPs, naming medical applications. This is because this synthetic approach removes the pathogenic factor, the virus, from the production process. This assists in the acceptance of this kind of particles in the application of treating (plant)-diseases.
Part 1: Modifying the CCMV VLP for site specific drug delivery
Introduction
CCMV will be one of the VLPs that we will be working on. We will focus on this VLP to prove the concept of using it as a Drug Delivery System.
Aim: Producing CCMV VLPs with epitopes on the outside or packaging coils in the inside, with the possibility to combine both to deliver a bio Nano carrier, with ligands on the outside and “medicine” packed on the inside.
