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): www.science.org/content/arti...

‘A sigh of relief’: New malaria drug succeeds in large clinical trial
As existing drugs falter because of resistance, the world gets a backup—but hard choices loom on how to use it

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.

Maria Bernabeu @mariabernabeu.bsky.social · 21/10/2025
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.

Maria Bernabeu @mariabernabeu.bsky.social · 21/10/2025
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.
100
Maria Bernabeu @mariabernabeu.bsky.social · 21/10/2025
More important, P. falciparum-stimulated immune cells cause BBB disruption, making the barrier leakier through decrease junctional VE-cadherin, increase contractility and apoptosis
100
Maria Bernabeu @mariabernabeu.bsky.social · 21/10/2025
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.

Maria Bernabeu @mariabernabeu.bsky.social · 21/10/2025
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

Maria Bernabeu @mariabernabeu.bsky.social · 21/10/2025

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!

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.
100
Maria Bernabeu @mariabernabeu.bsky.social · 09/09/2025
This effect was conserved in lung 3D microvessels, as well as an increase in neutrophil binding.

Maria Bernabeu @mariabernabeu.bsky.social · 09/09/2025
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

Maria Bernabeu @mariabernabeu.bsky.social · 09/09/2025
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/...

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...

Maria Bernabeu @mariabernabeu.bsky.social · 07/08/2025
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

Maria Bernabeu @mariabernabeu.bsky.social · 07/08/2025
The release of malaria products during egress leads to BBB disruption, including downregulation of tight and adherens junctional proteins as well as key vascular development pathways. This effect is localized at sites where parasites egress.

Plasmodium falciparum shows increased binding to ETS-endothelial cells. Exposure to parasite products caused a disruption on the endothelial barrier and we reveal a sustained and global downregulation of junctional, cytoskeletal and focal adhesion genes
