Have a look at two of the latest outputs from CRN Team Jakobsson, examples of true team effort and collaboration 🧠 💫 We are grateful to @asapresearch.parkinsonsroadmap.org for making this research possible! @jakobssonlab.bsky.social @kirkebylab.bsky.social @mollygale.bsky.social #RogerBarkerLab

Always a joy to join #EMBOMobileGenome -A week full of cool nature’s quirks and science along the friendliest crowd 🧬 Happy to have shared our work on ERVs in human brain evolution (talk by @jakobssonlab.bsky.social) and Parkinson’s disease (poster by yours truly) 🧠 #ASAP @jakobssonasap.bsky.social

Updated version of our preprint on how SETDB1-mediated H3K9me3 controls the expression of L1 elements in human neural progenitor cells. The new analysis in this revised version supports a role for active DNA demethylation of L1s in the absence of H3K9me3. www.biorxiv.org/content/10.1...

Todays labmeeting became a tribute to Jane Goodall. Such an outstanding role model. 🙊

New preprint from my lab! We describe how transposable elements are activated in Parkinson’s disease, which is linked to an interferon response. We believe this study significantly advances our understanding of transposons and their role in human brains. www.biorxiv.org/content/10.1...

Activation of transposable elements is linked to a region- and cell-type-specific interferon response in Parkinson's disease https://www.biorxiv.org/content/10.1101/2025.09.03.673956v1

New preprint of @trono-lab.bsky.social and my PhD work! By modulating SWI/SNF remodeling at ancient transposable elements - LINE/L2s and SINE/MIRs, a "noncanonical" KZFP called ZNF436 protects cardiomyocytes from losing their identity. 🫀heartbeat on 🔁 repeat www.biorxiv.org/content/10.1... #TEsky

Good times in Lund 🇸🇪 with @jakobssonlab.bsky.social. Beautiful campus, great food, and awesome science! Thanks Johan!

We had a fantastic guest speaker at our lab meeting this week who talked about the beautiful life of transposons and how they contributed to the evolution of the vertebrate brain. Thanks for the visit @cedricfeschotte.bsky.social !!

I am thrilled to share our preprint where we take advantage of the unique opportunities offered by human blastoids to uncover a human-specific mechanism potentially playing a role in preimplantation 🧵. www.biorxiv.org/content/10.1...

💥🥳 At long last, our latest paper is out! Gag proteins of endogenous retroviruses are required for zebrafish development www.pnas.org/doi/10.1073/... Led heroically by Sylvia Chang & @jonowells.bsky.social A study which has changed the way I think of #transposons! No less! 🧵 1/n

New online! Reactivation of retrotransposable elements is associated with environmental stress and ageing

Do you have transposon-related research cooking, with some cool results you are exciting to share? Start thinking about registering to #EMBOMobileGenome workshop! Nov 4-7 2025 in Heidelberg. One of the historical TE meetings, with a diverse and welcoming community. www.embl.org/about/info/c... 1/3

Interesting study on cell-type-specific aging using single-nuclei transcriptomics in the human neocortex. Not clear to me based on this graph that pace of aging is striking different across cell types. doi.org/10.1101/2025... see also https://doi.org:10.1038/s41593-024-01742-z
