The infectious diseases malaria and tuberculosis are responsible for 2.1 million deaths every year. Leiden researchers are currently testing a new tuberculosis vaccine.

The genomic DNA of every organism is organized and compacted in order to fit inside the cell. This is achieved by the joint action of numerous architectural proteins that aid in folding the genome. Genome folding is tightly interconnected with transcription, with genes in certain regions being silenced,…
