Summary

Story summary

Researchers at Shenyang Pharmaceutical University developed pig semen-derived exosomes in eye drops to reach retinal tissue.
The therapy targets diseases such as Alzheimer's, with retinoblastoma as an initial target.
The study, published in Science Advances on March 27, shows these exosomes deliver drugs through barriers.
Zhao Chunxia of the University of Adelaide noted the technique could improve delivery across the blood-brain barrier.
