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.

Macrophages of the immune system - cells that seek out and kill pathogens - are controlled by circadian rhythm, the 24-hour day-night cycle, which could have implications for disease treatment and vaccine efficacy.
