Gene editing therapies, like CRISPR, can correct mutations related to diseases, like retinal degeneration. Gene therapy might be successful if delivered before microglia activation and photoreceptor cell death in eye.

Oleic acid may benefit multiple sclerosis (MS), as MS patients tend to have lower levels of oleic acid; this suppresses T cell activity, leading to autoimmunity in the central nervous system.
