The 1st December each year marks World AIDS day. It is fitting, then, that this week has seen a colossal fundraising by Kymab, one of the life sciences companies at the forefront of research into the illness.
What do they do?
Kymab is discovering and developing human antibodies to treat diseases including HIV and malaria. The antibodies are produced from a single line of identical cells (‘monoclonal’) and are created inside laboratory-dwelling mice. These mice have been genetically engineered to contain the entire repertoire of human genes which affect antibody production (that is, genes which are responsible for some of the antibody variation between individuals).
This engineering process takes place without the removal of any mouse DNA, and without allowing the mouses’ own antibody-varying genes to interfere. Instead, 100 trillion human antibodies are created inside the animals, from which the most useful can be selected and extracted at will. The mice themselves are fertile, and behaviourally identical to their non-engineered peers.
