Proteomiska analyser av hjärtmuskelprover från patienter med AL-amyloidos avslöjar molekylära dysfunktioner bortom själva amyloidplaquerna — en upptäckt som kan förbättra diagnostik och patofysiologisk förståelse för kardial amyloidos. Forskare vid Göteborgs universitet och det italienska forskningsmaterialinstitutet analyserade proteinprofiler från endomyokardial vävnad för att kartlägga hur immunoglobulin-lätta kedjor (AL) och transthyretin (ATTR) påverkar omgivande vävnad. Tidigare proteomstudier fokuserade på själva amyloidstrukturen; denna undersökning adopterade ett holistiskt perspektiv på proteinnätverk i patientbiopsier. Resultaten kan möjliggöra mer exakt riskbedömning och personaliserad behandlingsstrategi, vilket är kritiskt då AL- och ATTR-amyloidos ofta diagnosticeras sent. För tillverkare av diagnostisk utrustning och läkemedelsutvecklare representerar detta en väg till biomarkörer som fångar sjukdomsprogression bortom bilddiagnostik.

Ferrioxalat-fotokatalys möjliggör direkt koppling av ketoner och alkener utan organiska katalysatorer eller externa reagenser — en utveckling som kan minska produktionskostnaderna i finkem och läkemedelssynthes.
