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.

The "designer cytokine" hyper-interleukin-6 reverses paralysis from spinal cord injuries in mice. Nerve cells were induced to produce hIL-6, delivering the blueprint into movement-controlling motoneurons.

Certain metabolites (small molecules that are byproducts of metabolism) may predict major depressive disorder (MDD). With 90% accuracy, researchers found a metabolic signature that predicts MDD relapse.
