🧫 Experiment Protocol
Exploratoryretinitis pigmentosaPde6brd10 mouse organotypic retinal explants with microglial depletionproposed
This experiment investigated the role of microglia in IGF-I-mediated neuroprotection by depleting microglial cells using clodronate-containing liposomes in organotypic retinal explants from rd10 mice. The study compared photoreceptor cell death in explants treated with IGF-I in the presence and absence of microglia. Results showed that microglial depletion diminished the neuroprotective effect of IGF-I, indicating that microglia are required for IGF-I's protective function. Interestingly, microglial depletion alone also moderately reduced photoreceptor cell death in untreated rd10 retinas, suggesting a complex dual role for microglia in retinal degeneration.
