Red blood cells don't always make their own heme - under stress, they scavange it from neighbors. Our new paper in @ScienceMagazine reveals a cell-nonautonomous heme acquisition pathway essential for erythroid hemoglobinization. #heme #erythropoiesis #anemia www.science.org/doi/10.1126/...

The great Ruslan Medzhitov strikes again!

Join us for the 2026 GRC Immunochemistry and Immunobiology "Immune Circuitry and Molecular Pathways in Tissue Homeostasis, Infection, and Disease" in beautiful Barcelona. June 28 - July 3, 2026. Great lineup of speakers! www.grc.org/immunochemis...

Incredible science at the CAML-GIMM PhD Meeting 2026! So proud of the outstanding presentations from our GIMM students across both campuses. 🧬 The meeting showcased "home made" cutting-edge research! Congratulations to Sonia Trikha, Madalena Pereira and Miguel Mesquita! @gimmfoundation.bsky.social

#DirtyIsBetter! @rmedzhitov.bsky.social, Erickson &co show @nature.com that pet shop mice are protected from #allergy thanks to cross reactive type I (or tolerogenic) immune memory that prevents type II allergen-driven responses! doi.org/10.1038/s415...

#WeekendRead! #SameSameButDifferent! #FirstLove! Its discovery changed our understanding of the functioning of innate immunity and of the immune response in general, but actually not all TLR4s are equal, check this out @jimmunol.bsky.social 👇👇👇 academic.oup.com/jimmunol/art...

This is not an anomaly. It is a method. Correction becomes harassment Public discourse becomes “stalking” Expertise becomes abuse Evidence is replaced by narrative Sex and victimhood are instrumentalised Reputation damage is the objective

New research led by @karinaxavierlab.bsky.social at 🇵🇹 @gimmfoundation.bsky.social demonstrates that a harmless strain of 🦠 #Klebsiella – discovered by chance in 🧫 laboratory experiments – can eliminate #infections and reduce gut inflammation in mouse models of inflammatory bowel disease. #IBD

Homeostatic control of energy metabolism by monocyte-derived macrophages @elmiguelche.bsky.social and colleagues show that macrophages sense dysregulated iron metabolism in parenchymal cells and respond by sustaining mitochondrial function in affected cells www.embopress.org/doi/full/10....

🧵 Thrilled to share our new work in @embojournal! Over a century after Metchnikoff recognized macrophages as central to organismal homeostasis, we reveal how they act as metabolic guardians through an unexpected mechanism. www.embopress.org/doi/full/10.... (1/9)

of the influenza vaccine is low (against infection). What is forgotten is the protection from non-communicable diseases. What if you could reduce your risk to heart disease by 40%? What is you could reduce you risk to dementia by at least 10%? That is what vaccines do! 3/10

A recent study based on observations in humans and experiments in mice proposes that induction of bilirubin production in response to Plasmodium spp. infection is an evolutionary conserved mechanism against malaria. 🧪 www.science.org/doi/10.1126/...
