New therapeutic approach for Parkinson’s and other neurodegenerative diseases

Xiang-Dong Fu, PhD, has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it. But a single discovery has launched Fu into a completely new field: neuroscience.

Protein design can solve the puzzle of Parkinson's disease

Dopamine is a neurotransmitter involved in everything from higher cognitive functions to motor control, motivation, arousal, reinforcement, and sexual gratification, the receptors it acts on have been a longstanding target for treating disorders like Parkinson's disease, which is caused by the degeneration of dopamine-using neurons that control movement.

Anesthetic drug Ketamine uses serotonin receptors to relieve depression

Ketamine is a drug used to induce general anesthesia. It has also been found to act rapidly to relieve depression that has failed to respond to two other rounds of medication. A new study published in the journal Translational Psychiatry in May 2020 reports the mechanism of action of the drug, which was hitherto unknown. This could help find new ways to treat this debilitating and sometimes fatal condition.
