Pericytes orchestrate a tumor-restraining microenvironment in glioblastoma - Nature Communications Improved understanding of the tumor ecosystem in glioblastoma is critical for developing new treatment strategies for the disease. Here, the authors identify pericytes as an active paracrine signaling...

Spatial and temporal dynamics of cancer-associated fibroblast niches in breast cancer - Breast Cancer Research Breast Cancer Research - Cancer-associated fibroblasts (CAFs) are the main constituents of the tumor microenvironment. Several studies have delineated CAF heterogeneity in different types of...

New paper out from the @kpietraslab.bsky.social lab.
I am happy to share that my first-author paper is now published. We map the spatial and temporal dynamics of cancer-associated fibroblasts in breast cancer using integrated spatial proteomics and transcriptomics.

Phenotypic Screening Identifies Flunarizine as an Inhibitor of Radiotherapy-Induced Astrocyte Reactivity with Therapeutic Potential in Glioblastoma Radiotherapy is part of the standard-of-care for glioblastoma, yet tumors invariably recur as incurable lesions post-treatment. Recent studies suggest that radiation-induced astrocyte reactivity foste...

📣 Preprint alert! Happy to share our latest work, in which we identify Flunarizine as an inhibitor of astrocyte reactivity with therapeutic potential in glioblastoma (GBM). Details in 🧵:

I'm delighted to host @ggargiul.bsky.social for a talk in the LUCC seminar series today. Medicon Village Auditorium @ 1.30 - you don't want to miss out if you're in Lund! Welcome!

A huge congratulations on yet another momentous achievement!

Kristian Pietras – Årets cancerforskare 2025 Kristian Pietras forskar om hur celler i blodkärl och bindväv påverkar cancerns möjlighet att växa eller dö. Nu tilldelas han utmärkelsen Årets cancerforskare.

We are proud to share that our PI has been named Cancer Researcher of the Year by @Cancerfonden! This well-deserved recognition highlights not only his outstanding contributions to cancer research but also his creativity in tackling scientific challenges and his inspiring leadership within our team.

And here's @rebeccarosberg.bsky.social (with others) accepting her poster prize to conclude a wonderful symposium in Paris 🤩🔥🧠🇫🇷

At the Brain Tumor Microenvironment Symposium @institutducerveau.bsky.social, Sebastian Braun presented our comprehensive study of pericytes in GBM 🤩. Pericytes act as guardians of the peri-vascular niche to prevent malignant cell invasion, read more at www.biorxiv.org/content/10.1...

We're excited to be at the Institute du Cerveau in Paris for the brain tumor microenvironment symposium 🧠 Here's Pauline Jeannot with the first presentation of the day from the lab 🔥

...and here's Karolina Smolag @karolinasmolag.bsky.social delivering the second Pietras lab talk of the day 🤩 We also have a couple of posters so please check them out if you're with us in Paris!

We have been waiting impatiently but can finally share our latest efforts in understanding the biology of the TGF-beta type I receptor ALK1 (gene name ACVRL1), see graphical abstract in post and the full article here: www.jci.org/articles/vie...
