Description preview
Contact PD/PI: CAI, JIYANG
The primary goals of this project are to investigate the transfer of extracellular microRNAs (miRNA) between
retinal pigment epithelium (RPE) and microglia as a means of intercellular communication and to evaluate the
use of engineered RPE-derived extracellular vesicles (EVs) as an interventional strategy to mitigate…
