Come to Biomalpar xxii!!! We have an outstanding line up of speakers!!!
It is a true honor to be an organizer of Biomalpar. It was the first conference I ever attended during my 2nd PhD year so it feels special.
And don't miss the beautiful poster image from Hannah Fleckenstein!

This will be done in collaboration with Chris Moxon at @uofglasgow.bsky.social and in Blantyre, Malawi. We will also have the support of @epetsalaki.bsky.social at @ebi.embl.org for advanced computational analysis.
Thanks for the support of @caixaresearch.bsky.social to continue our efforts to use tissue engineering to study cerebral malaria. We will develop stem-cell derived immunocompetent BBB models with microglia to study malaria, in a side by side comparison with spatial transcriptomics in patients.
I’ve been in Toronto at the #astmh meeting these past few days and last night some very good news was presented here: A new malaria drug has proven efficacious in a large trial and could soon be approved.🧪
My story in @science.org (and 🧵on why it's important to come):

We certainly did both 😊 Great talk!
Thank you very much for highlighting our work. This is one of our first big stories coming from out the lab, so we are very excited!
📣Announcing the 4th edition of the EMBL‑IBEC Conference on “Engineering Multicellular Systems”, taking place 11–13 March 2026 in Barcelona. Exploring organoids, mechanobiology, embryo models, organ-on-chip systems, multiomics and more. Abstracts open now!

Huge thanks to @mariabernabeu.bsky.social and to everyone else who contributed and made this project possible 🎉
Thanks again @alinabatzi.bsky.social for a titanic work, and all the lab. @jamesasharpe.bsky.social lab and Lars Steinmetz lab for computational help. Miguel and Mireia at UPF for insights in immune-endothelial responses, and my ❤️ friend @moncunill.bsky.social, for getting us into deep immuno!
Our study shows the power of using bioengineered models in combination with deep single cell profiling to study complex immune responses.
For the first time, we can introduce different infection relevant drivers into human models to identify their individual role in tissue damage.
Alina finally integrated the scRNAseq immune dataset with our recently published dataset of the 3D-BBB model being exposed to P. falciparum. We identified shared and dominant disrupted pathways (JAK-STAT!) in all cells. As well as parasite/immune-specific disruptive pathways on endothelial cells.
Barrier disruption was mostly mediated by locally acting granzyme B and IFNy secreted by gd T cells and NK cells. We could prevent barrier disruption by preventing immune cell binding with anti-ICAM-1 antibodies.
More important, P. falciparum-stimulated immune cells cause BBB disruption, making the barrier leakier through decrease junctional VE-cadherin, increase contractility and apoptosis
Monocytes, gd T cells and NK cells cells secrete TNFa and IFNg, causing a strong inflammation and activation of all BBB cells, accounting for 20% of changes in the transcriptome.
In a project spearheaded by the relentless @alinabatzi.bsky.social, we used an immunocompetent 3D-Blood brain barrier (BBB) model and found that Plasmodium falciparum stimulated immune cells accumulate much more to the BBB (mostly T-cells), driven by changes on LFA high-affinity conformation
Pre-print alert 🚨
We answer a longstanding question in the field. Do immune cells cause cerebral malaria?
The answer is YES!!!! And independently of P. falciparum accumulation in the brain.

Just hot out of the press! Rory developed a 3D microvessel model that recapitulates physiological pericyte coverage. We found that Plasmodium falciparum egress products disrupt the barrier and halt ang-1 secretion. The activator AKB-9778 could rescue barrier disruption! Congratulations, Rory!
I think I didn't 🙈 but @rorykmlong.bsky.social left everything ready, so there was a very minimum chance for me to screw up! ☺️
Then and now... 2022. Helping @rorykmlong.bsky.social and François on midnight experiments. 2025 Helping Rory to finish experiments for François' paper revision. Bonus points: The surprise of new lab members when they found me in the TC room after being > 1 year at my desk.
Back from #ParaFrap! What a fantastic meeting. I feel very privileged to be part of this community! Specially in my heart the new generation of kickass PIs/GL ❤️ (mostly women dominated💪🏻)
This article highlights the importance of agressive antypiretic treatment in malaria infections and has potential consequences for other infections and brain injuries!!!!
We could reverse this highly negative effect by protecting the endothelial glycocalyx with Batimastat, an MMP1 inhibitor.
This effect was conserved in lung 3D microvessels, as well as an increase in neutrophil binding.
Just a short 30 min exposure to 40C, common in malaria patients, significantly increased parasite binding to 3D microvessels at multiple flow conditions. We found this occurred in several parasite lines with tropism in the brain, without apparent changes in their endothelial receptors EPCR and ICAM
Have you ever wondered what happens with your microvessels after exposure to high temperature in fever? In this preprint former postdoc (ans soon to be PI) Viola Introini found that high temperatures cleaves glycocalyx , having severe consequences in malaria www.biorxiv.org/cgi/content/...
We are searching for an enthusiastic scientist to join our team and establish annual killifish as a model system for early developmental biology and biophysics! @embl.org @embldbunit.bsky.social

Please re-post 🙏
It has been amazing that you were my (co-)first PhD student. Amazing journey. You should be proud of everything you achieved
A big thanks to everyone, who contributed to the project.To the full Bernabeu group, as this was a team project! As well as our @embl.org collaborators @jamesasharpe.bsky.social group, @yschwab.bsky.social's team and Lars Steinmetz group!
More important, we could reverse the increase in vascular barrier permeability induced by malaria products with Ruxolitinib, a JAK-STAT inhibitor! This is super exciting with the drug now being tested in CHMI studies. www.medrxiv.org/content/10.1...
We also found that falciparum egress products activate interferon and antigen presenting pathways in all the cells that compose the BBB, endothelial, astrocytes and pericytes. Including JAK-STAT as one of the key signaling inflammatory hubs
