In this episode of the Epigenetics Podcast, we caught up with Erna Magnúsdóttir from the University of Iceland to talk about her work on the role of Blimp-1 in immune-cell differentiation.

The Magnúsdóttir Lab is interested in how the mammalian genome is interpreted in a context dependent manner, leading to different cellular states, by using mouse primordial germ cells as well as mouse and human B-cells as model systems. More specifically, the team is interested in the Transcription Factor Blimp-1 and its effect on immune cell differentiation. Next to its function in immune cells, Blimp-1 also plays a role in Waldenström’s macroglobulinemia. The lab hopes to reveal the intricacies in disease progression and alteration in cellular states to increasingly aggressive tumor behavior.
