Retroviruses – brain secret agents.

In Brain Disorders, Brain Science, DNA, Genetics by Brainy Days Ahead

Over millions of years retroviruses have been incorporated into our human DNA, where they today make up almost 10 per cent of the total genome. A research group at Lund University in Sweden has determined that several thousands of the retroviruses that have established themselves in our genome may serve as “docking platforms” for a protein called TRIM28. This protein has the ability to “switch off” not only viruses but also the standard genes adjacent to them in the DNA helix . This makes them a possible tool for evolution, and also a possible underlying cause of neurological diseases.
