A team of Chinese scientists has developed a novel treatment for Alzheimer's using eye drops made from pig semen-derived exosomes, which may help breach the brain's defenses against the disease.

An innovative therapy using pig semen-derived exosomes, engineered into eye drops capable of penetrating deep into retinal tissue, may hold the key to breaching the brain’s defences against diseases like Alzheimer’s. This breakthrough, led by Professor Zhang Yu at China’s Shenyang Pharmaceutical University, originally targeted a rare childhood eye cancer retinoblastoma that often resists conventional treatments due to its delicate location near the brain.
