episode 80: Characterization of Epigenetic States in the Oligodendrocyte Lineage (Gonçalo Castelo-Branco)

In this episode of the Epigenetics Podcast, we caught up with Goncalo Castelo-Branco from the Karolinska Institute to talk about his work on the characterization of epigenetic states in the Oligodendrocyte Lineage.

The group of Gonçalo Castelo-Branco focuses on characterizing epigenetic states of oligodendrocytes with the aim to understand their contribution to diseases like multiple sclerosis. To do this the group used single-cell RNA-Seq to identify sub-populations of oligodendrocytes. Furthermore, the team pioneered in improving CUT&Tag and applied it to the single-cell space as well as developed spatial CUT&Tag. More recently they used nanobodies in an optimised version of the single cell CUT&Tag that allows simultaneous probing of three epigenomic modalities at single-cell resolution, using nanobody-Tn5 fusion proteins. The three modalities encompass chromatin accessibility as measured via ATAC-Seq and two histone post-transcriptional modifications.
