Elena and Rinako present: MicroRNA-155 controls affinity-based selection by protecting c-MYC+ B cells from apoptosis
This is a video summary presenting new findings published in The Journal of Clinical Investigation about the role of microRNA-155 in the affinity-based selection of B cells. Two of the paper’s authors, Rinako Nakagawa and Elena Vigorito, provide a personally guided tour of their results. The results of this study may extend our understanding of the pathogenesis of lymphomas and open up new therapeutic targets.

The inner galaxy of your genes
A video by researchers at the Babraham Institute allows a glimpse into the physical interactions occurring in the genome. Reflecting the beauty of a distant galaxy, the video shows a three-dimensional view of the contact points between the 22,000 genes in the mouse genome.
The video clip shows memory T cells (green) actively patrolling the skin surface (blue) in case of re-infection with a similar pathogen. Find more videos like this on our Weapons of Microscopic Destruction website, plus games and more information on how the immune system works.

A new method for visualising chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with.
