Linköpings universitet har utvecklat en bioelektronisk "neural pixel" som kombinerar kemisk stimulering och elektrisk avläsning på samma mikroskopiska plats. Enheten använder organiska elektroniska ledande polymerelektroder för att registrera epileptiforme urladdningar i musens hippocampus samtidigt som den levererar GABA (gammaaminosmörsyra), en inhibitorisk neurotransmittor, direkt genom samma elektroder via en organisk elektronisk jonpump. GABA-tillförsel stoppade epileptiforna aktiviteter som uppmättes in situ. Tekniken öppnar vägar för implanterbar terapi med automatiserad återkoppling, där lokalt registrerade signaler styr lokal frisättning av specifika läkemedel. För aktörer inom medicinteknologi och neurologisk farmakologi blir detta relevant — möjligheten att sätta båda funktioner på en enhet i cellskala minskar invasivitet och ökar behandlingens effektivitet. Utvecklingsvägen från experimentell modell till klinisk tillämpning kräver ytterligare validering, men konceptet signalerar en ny arkitektur för neuromodulationsterapier.

**Kostnad-effektiv fMRI-avbildning möjlig med standard-utrustning** Forskare vid Linköpings universitet presenterar en metodutveckling som ökar känsligheten i hjärnaktivitetsmätningar utan att kräva dyr ny hårdvara. Genom att integrera "shifted echo"-teknik i vanlig magnetresonanstomografi kan man minska upptagningsintervallet (TR) till under 1 sekund samtidigt som datavolymen hålls hanterbar. Studien jämförde fyra olika inställningar på 11 försöksdeltagare. Den optimala metoden — där data genomsnittades två och två — visade 25–30 procent förbättrad signalkvalitet jämfört med referenssekvensen. Detta uppnåddes utan att öka datamängden nämnvärt. Resultatet är affärsmässigt relevant för kliniker och forskningscentra som saknar infrastruktur för experimentell avbildningsteknik. Metoden gör avancerad funktionell hjärnmappning tillgänglig på befintlig utrustning och minskar behovet av specialiserad support, vilket påverkar investeringsbeslut för stora medicinska institutioner.

PROTAC-läkemedel designades för att rikta in sig på och bryta ned sjukdomsrelaterade proteiner, men utvecklingen strandas ofta på linkergeometri. COMPASS är en beräkningsmodell som screnar linkersekvenser innan syntes, vilket sparar resurser och försnabbar utvecklingen. Modellen klassificerar vilka linker-kombinationer som kan bilda funktionella ternära komplex mellan E3-ligaser och målproteiner. Forskarna testade COMPASS mot 20 kristallografiska strukturer med submånometer-noggrannhet och validerade retrospektivt mot 112 redan syntetiserade PROTAC-molekyler från åtta E3/POI-system. Modellen uppnådde 93 procent korrekt klassificering av degraderande PROTAC:er. Institutioner i Rennes, Eindhoven, Göteborg och Rennes samarbetade i studien, finansierad bland annat av Vetenskapsrådet och Svenska Cancerfonden. För bolag som utvecklar PROTAC:er minskar detta utrustningens och försöksomkostnaderna väsentligt och förkortar vägen till kandidatval.

Researchers tested 242 proteins against 790 metabolites and found that while 20% showed statistical associations, fewer than 0.1% actually caused metabolic changes. The finding reshapes how drug developers should prioritize protein targets and could save millions in failed clinical trials by cutting unproductive research paths early.EN

A new treatment for hereditary transthyretin amyloidosis—a rare genetic disorder that damages nerves—works comparably well in both sexes, according to analysis of a late-stage trial.

Forskargrupp kring Karolinska Institutet identifierar en ny familj antimikrobiella peptider med spegelsymmetrisk struktur i svampar och insekter. Peptiderna består av cirka 85 aminosyror och bildar en kompakt tvådelad arkitektur som skiljer dem från tidigare kända antimikrobiella peptider. Generna förekommer i flera svampar och några leddjurarter, vilket indikerar ett konserverat försvar mot patogener. Strukturen kan möjliggöra enklare syntes och stabilare farmakologiska egenskaper än konventionella peptider. Arbetet genomfördes vid Karolinska Institutets Division för Molekylär Neurobiologi tillsammans med forskarlag från Österrike och Kina. För aktörer inom antimikrobiell läkemedelsutveckling är fyndet relevant: nya peptidkällor kan accelerera upptäckten av kandidatmolekyler mot antibiotikaresistenta bakterier. Resultatens translationspotential beror på peptidernas biologiska aktivitet och produktionsförutsättningar, vilka kräver vidare funktionell validering.
