In Vivo Imaging of Retinal Microglia in a Mouse Model of Glaucoma

Microglia-activatie en microgliose zijn de belangrijkste reacties op chronische neurodegeneratie. Hier presenteren we werkwijzen voor in vivo visualisatietechnieken retinale CX3CR1-GFP + cellen door microgliale confocale Ophthalmoscopie, en drempel en morfometrische analyses worden geïdentificeerd en gekwantificeerd hun activering. We monitoren microglia veranderingen tijdens de vroege stadia van leeftijdsgebonden glaucoom.

Dit protocol beschrijft een chronische craniale venster implantatie techniek die kan worden gebruikt voor longitudinale beeldvorming van neuro-glio-vasculaire structuren, interacties, en functie in zowel gezonde als zieke omstandigheden. Het dient als een aanvullend alternatief voor de transcraniële beeldvormingsbenadering die, hoewel vaak de voorkeur, een aantal kritische beperkingen bezit.
