Uppsala Universitet har utvecklat en inducerbar CRISPR-Cas9-ram för genredigering av gram-positiva bakterier som tidigare varit svåra att modifiera genetiskt. Metoden utnyttjar bakteriernas eget Cas9-system istället för externa plasmider, vilket minskar komplexiteten vid funktionell genomanalys av icke-modellbakterier. Många industriellt och ekologiskt viktiga bakterarter saknar etablerade genetiska verktyg, vilket begränsar förvärvandet av kunskaper om deras funktionella egenskaper. Forskargruppen löste denna flaskhals genom att aktivera endogena CRISPR-system, vilket öppnar för snabbare karakterisering av värdassocierade och miljöbundna gram-positiva species. För FoU-ledare inom bioproduktion, såsom fermentationsbaserad tillverkning och probiotikautveckling, tillhandahåller tekniken ett verktyg för att raskt testa genotyp-fenotyp-relationer utan att konstruera nya vektorsystem. Denna metod förkortar utvecklingstiden och minskar kostnaderna för att validera kandidatceller innan klinisk eller industriell skalning.

CD163-receptorn på makrofagers yta minskar när 7-oxysterolar triggrar celldöd — en upptäckt som kan förklara varför vissa makrofager blir skörare i aterosklerosbetad. Forskare vid Linköpings universitet exponerade THP-1-makrofager för en blandning av 7β-hydroxikolesterol och 7-ketokholesterol (2mix), två oxysterolar som ansamlas i ateromatösa lesioner. Resultatet visar dosberoendet: ju högre 2mix-exponering, desto lägre CD163-nivå på cellöverflöden. Samtidigt steg reaktiv syresspecies (ROS) och apoptosmarkörerna markant. CD163-uttrycket korrelerade omvänt med både celldöd och oxidativ stress. Studien föreslår att CD163 skyddar makrofager mot oxysterol-inducerad apoptosis. För läkemedelsföretag som utvecklar atheroskleros-terapier betyder detta att CD163-modulering kan påverka plackstabilitet. Resultat från Linköpings kliniska avdelning för obstetrik och gynekologi och institutionen för biomedicinsk och klinisk vetenskap öppnar nya målstrukturer för inflammationshämmande strategier.
