Super happy to announce the latest work from my lab together with Hemali Phatnani @nygenome.org & NYGC ALS Consortium! We've combined ALS patient profiling (100s!), ML classifiers and matched bulk/single-cell data to dive into ALS Molecular Subtypes #NIHfundedResearch www.cell.com/cell-reports...

Today… 🇸🇪

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

New preprint from our lab! Great collaboration with the labs of Karolina Pircs and Csaba Kerepesi from Budapest. We built molecular aging clocks for the human brain using single-nuclei RNA-seq data. doi.org/10.1101/2025...

Read this preprint today from @jakobssonlab.bsky.social lab that profiles and CRISPRi perturbs L1 transcription in hiPSCs and cerebral organoids. It is extremely well done. The L1 CRISPRi phenotype in the organoids is subtle and variable but interesting. 1/n www.biorxiv.org/content/10.1... #TEsky

A mechanism for maintaining and spreading H3K9me3 in heterochromatin from the Fejes Toth and Aravin labs that depends on the local H3K9me3 density: HP1 dimers recruit SetDB1 to chromatin by simultaneously binding H3K9me3 on histone H3 and auto-methylated SetDB1. www.biorxiv.org/content/10.1...

🧠🔬 Great meeting last Friday in Copenhagen between the Kirkeby and Jakobsson labs — exciting experiments coming up to investigate transposons in PD in vitro models! @asapresearch.bsky.social @kirkebylab.bsky.social @jakobssonlab.bsky.social

New preprint from our lab. Led by the outstanding @anitaada.bsky.social and @raquelgarza.bsky.social. Funded by @asapresearch.bsky.social and @vetenskapsradet.bsky.social. LINE-1 retrotransposons regulate the exit of human pluripotency and early brain development www.biorxiv.org/content/10.1...

If there's something we don't understand I assume transposons are responsible unless proven otherwise

Profiling and targeting young L1s is no easy matter 🧐 check out our new preprint to see how we delve into transcriptional and epigenomic profiling of L1s, and investigate their involvement in pluripotency and early brain development 🧠

We profiled the effects of our CRISPRi system targeting young L1 elements in human pluripotency & brain development. These elements deeply impact our transcriptome, but also have very distinct effects on their nearby genome. Check it out!! 🧬👾 #TEsky #CRISPR #L1 #development #epigenetics

Tomorrow is my last day as Director of the Lund Stem Cell Center. It has been a fantastic four years and I am so happy to pass over the torch to my close colleague Malin Parmar, who will lead the center together with Göran Karlsson in the coming years.

How does the ORF1p perform its multiple functions to facilitate LINE1 retrotransposition? And what enables its ability to also facilitate replication of other retrotransposons? Find out in our newly published paper in Nucleic Acids Research doi.org/10.1093/nar/...
