Support cells protect the retina from low blood flow damage through a calcium signal and cell cleanup process

Astrocyte-derived exosomes (ADEs) may provide protection to retinal microvascular endothelial cells during retinal ischemia-reperfusion injury.

• Retinal ischemia-reperfusion injury is associated with microvascular damage and inflammation, negatively impacting vision.
• Astrocyte-derived exosomes are suggested to offer neuroprotective effects.
• The specific role of ADEs in protecting retinal microvasculature remains uncertain.
• This study focuses on the effects of ADEs on retinal microvascular endothelial cells in the context of retinal ischemia-reperfusion injury.
