Noise isn’t always bad! Sometimes it helps us see the unseen. 🚀 Our new preprint shows how stochastic resonance boosts single-cell proteomics signals. 👉 biorxiv.org/content/10.1101/…

For decades, scientists believed that stable isotopes in our tissues reflected our diet with a small correction. Our new preprint shows it’s more complex: isotopes actively shape biology and converge in surprising ways.

New paper published. Hopefully our results will lead to developing novel biomarkers and therapeutic interventions against traumatic brain injury in the long run.
Our paper on identification of biomarkers and therapeutic targets in traumatic brain injury (TBI) is now published. Here, we use PISA to dissect the early molecular events and proteome solubility changes following a dynamic injury to neurons.

Check out our new work on PISA-REX for analysis of proteomes in the three dimensions of redox state, solubility and expression for target identification.
Finally after a year of data analysis, fine-tuning and writing, one of my most important papers is online. It is about a tool for 3D analysis of proteomes in target deconvolution (1).

This toy example may change how you look at tSNE & UMAP.
They find clusters in the most uniform data possible.

Our new collaborative study shows that NCF1-dependent production of ROS protects against lupus by regulating plasmacytoid dendritic cell (pDC) development and functions. ROS deficiency enhances pDC generation through the AKT/mTOR pathway.

DOPA is just as good (or even better!) than Vitamin C - when it comes to protecting tissues from free radicals. 🛡️🔥 Proud of this largely experimental (!) work of our lab. 🎉🎉🎉 Thanks to amazing collaborators @RedoxDKFZ @RZLabKI @prisnerlab and others!

New work from our lab at @karolinskainst uncovers massive solubility changes of neuronal proteins upon simulation of traumatic brain injury. #TBI #neuroscience #proteomics #TeamMassSpec
Excited to share our work, where we combine a novel apparatus with state-of-the-art solubility proteomics and simulate traumatic brain injury, to uncover mechanisms of neuron damage, for ultimate identification of diagnostic and therapeutic biomarkers.

In our new preprint, we identify the O-glycosylated substrates of GALNT1 using versatile proteomics tools. Arguably one of the most challenging PTMs to study. We close in on a motif too.

Do you know isoaspartate acts as a molecular clock in aging? We collaborated with Prof. @CharlotteTeuni1 and Dr. Guo to test the link between isoaspartate and Alzheimer's disease etiology on A&D journal doi.org/10.1002/alz.12735 @alzdemjournals @alzassociation @ISTAART
