Forskare vid Leibniz-Forschungsinstitut für Molekulare Pharmakologie i Berlin har kartlagt strukturen av ett jättevirusets proteinkomplex med en integrerande metod som kombinerar korslänkningsmassspektrometri, kvantitativ proteomik och kryo-EM. Studierna allokerar 88 virala proteiner till olika subkompartment i virionen och föreslår topologier för 25 inre membranproteiner. Arbetet identifierar åtta kapsidbehöriga komponenter, inklusive proteiner som förankrar kapsidskal till membranen – kritiska punkter under virusmodningen. Resultaten öppnar vägen för att förstå biologisk arkitektur i svårkaraktäriserade system utan homologa referenser. För leverantörer av analysverktyg inom strukturell biologi och proteomik är detta en validering av integrerande arbetssätt. För virusvaccin- och antivirala läkemedelsutvecklare signalerar det nya angreppsytor på virala strukturer som tidigare varit dolda. Studien utgörs av tysk-japansk-svensk forskningsmiljö med stöd från EU, DFG och Vetenskapsrådet.

The finding overturns decades of assumptions about how these vesicles work and could unlock more efficient therapeutic designs for treating everything from heart disease to COVID-19.EN

Researchers have identified why lung cancer becomes more aggressive with age—a cellular stress response called ATF4 reprograms tumors to spread rather than grow locally. The finding opens a new drug target and explains why age is such a powerful predictor of cancer outcomes, potentially transforming how oncologists treat older patients.EN

A major Swedish study tracking nearly 15,000 people found that antibiotics can disrupt the gut microbiome for up to 8 years after use. The finding matters to pharma companies, healthcare systems, and insurers because it suggests the hidden costs of antibiotic prescriptions extend far longer than previously known, potentially affecting disease risk and treatment outcomes long after patients finish their pills.EN

Researchers mapping Baltic herring DNA found that fish populations rapidly evolve distinct traits based on local conditions—spawning time, temperature, and salinity—despite interbreeding. The discovery has implications for fisheries management and understanding how wild populations survive environmental shifts.EN

Scientists discovered that the brain's own scar tissue plays a surprising dual role in spinal cord recovery: it first limits neuronal plasticity but later stabilizes new nerve connections. This challenges the prevailing strategy of removing scar tissue after injury, suggesting that timing-based therapies—not blanket scar removal—could improve outcomes for paralysis and neurological injury.EN

Researchers have mapped how bacteria hide antibiotic-resistant variants within susceptible populations—a phenomenon that causes treatment failures. The finding reveals how resistance genes copy themselves under drug pressure and partially revert when antibiotics stop, opening new avenues for diagnostic tools and therapies that could outsmart bacterial evasion tactics.EN

Researchers have discovered that TNF, long blamed for suppressing bone marrow function, actually plays a nuanced role—sometimes helpful, sometimes harmful—depending on context. The finding could reshape development of therapies for blood disorders, cancer, and immune diseases worth billions in annual healthcare spending.EN

Spatial metabolomics erbjuder högupplöst kartläggning av små molekyler direkt i vävnad och kan revolutionera diagnostiken inom lungmedicin genom att avslöja metabolisk variation mellan olika vävnadsregioner. Metoden bygger på masspektrometri-baserade tekniker som MALDI och DESI för att generera pixelupplöst metabolitöversikter. I lungforskning har spatial metabolomics redan identifierat region-specifika metaboliska signaturer kopplade till surfaktantomvandling, lipidmediatorlokalisering, fibros och tumörassocierad fosfolipidrubbning. Denna förmåga att koppla lokal biokemi till fysiologi och sjukdomsmekanismer öppnar nya vägar för sjukdomsförståelse. Karolinska Institutet leder utvecklingen tillsammans med Respirationsmedicin vid Karolinska sjukhuset. Utmaningar kvarstår: begränsad känslighet, svåridentifierade metaboliter och inkompatibilitet med standardiserad vävnadskonservering. Integration med spatial transkriptomik och proteomik kommer att möjliggöra flerlagers molekylär kartläggning och påskynda utvecklingen av nya biomarkörer för lungsjukdomar.

Researchers have created nanobodies—small proteins derived from camel antibodies—that can selectively turn bacterial stress responses on or off by locking enzymes in specific shapes. The discovery opens a path to new antibiotics that work through an entirely different mechanism, potentially circumventing resistance while also suggesting how to suppress bacterial virulence in infections.EN

Researchers have identified the precise cellular pathway by which Shiga toxin—produced by a common food-borne pathogen—forces cells to release ATP, triggering inflammation and organ damage.

Genetisk forskning från Gotland under yngre stenåldern visar att såväl jordbrukare som fiskare var exponerade för pestbakterier — en upptäckt som kan omvärdera hur forskare modellerar patogeners spridning i förhistoriska samhällen. Uppsala universitet analyserade DNA från sex jordbrukare från traktbärkulturen och 19 fiskare från gropkeramikkulturen som levde parallellt omkring 3300–2800 f.Kr. Resultaten visar att olika stammar av Yersinia pestis cirkulerade bland båda grupperna trots skilda livsmedel och möjligen begränsad genetisk blandning. Magdalena Fraser och hennes team detekterade på grund av höga genomsekvenser att genflöde mellan grupperna var minimallt före deras koexistens. Upptäckten ställer nya krav på hur infektionsmodeller konstrueras för småsamhällen och möjliggör framtida studier av sjukdoms- och populationsdynamik i tidiga lantbrukssamhällen.

A 46-year analysis of Sweden's malignant hyperthermia registry uncovered that reactions predominantly strike young people and are often triggered by subtle muscle symptoms during anesthesia.
