Co-option of certain transposable elements as regulatory elements in specific cerebellar cell states, e.g. HERVL in rhombic lip–derived neuroblasts. Led by awesome Tetsuya @tyamadat.bsky.social, together with @ioansarr.bsky.social and @kaessmannlab.bsky.social

Our manuscript on the co-option of TEs as cerebellar CREs is now officially published in @natcomms.nature.com! Huge thanks to @kaessmannlab.bsky.social @marisepp.bsky.social, and @ioansarr.bsky.social for the fantastic collaboration throughout this project! www.nature.com/articles/s41...

According to @edvardmoser.bsky.social, director of the Kavli Institute for Systems Neuroscience, the four recipients of the Kavli Prize in Neuroscience challenged what had long been regarded as a central dogma in neuroscience. By Alissa de Chassey www.thetransmitter.org/awards/four-...

Protein synthesis pioneers garner Kavli neuroscience prize

Their research revealed how neurons synthesize proteins in previously unrecognized places.

Thrilled and honored to receive the Ernst Schering Prize 2026!🎉 Also deeply grateful to have been elected to the German Academy of Sciences. Both are recognitions of our whole group – I’m immensely thankful to all team members, past and present!❤️ tinyurl.com/hjrejv3p tinyurl.com/muw7j6mr

Huge congrats from our whole lab to Sir David Attenborough on his 100th birthday!!! 🎉🥳❤️ I had the honor of meeting him - and being interviewed by him - in 2013 for his BBC documentary "Rise of Animals: Triumph of the Vertebrates", which featured part of our work.

Very proud of this and so cool that enhancer-level models can predict the effect of genetic variation. There is so much personal variation in terms of gene regulation in the human brain, it is fantastic to uncover this thanks to technology (whole-genome sequencing and single-cell multiomics) and AI

Exciting study by @lenakutscher.bsky.social and @doctorpauln77.bsky.social on male bias in medulloblastoma: “testosterone and the XY genotype cooperate to increase the abundance of specific cerebellar progenitor populations” Elegant use of Four Core Genotypes mice + recapitulation in organoids

New preprint alert! I'm excited to share our latest preprint where we investigate the underlying developmental causes of the male bias in the pediatric brain tumor Group 3/4 medulloblastoma. www.biorxiv.org/content/10.6...

graphical abstract for "Developmental determinants of male bias in medulloblastoma" preprint. We propose that boys are more likely to develop Group 3/4 medulloblastoma more vulnerable cells-of-origin are available for transformation. Specifically, GC_UBC progenitors in the developing cerebellum are more abundant in male murine embryos, as a result of testosterone exposure and the XY genotype.

Inhibitory neurons are among the most transcriptomically diverse class of neurons in the CNS, with some brain regions having 60+ distinct cell types. Do humans share the same repertoire as rodents? Birds? Fish? 1/13
