Parkinson's disease breakthrough seen in mouse model

Researchers from the University of California San Diego School of Medicine have found a way to create new neurons in a mouse model of Parkinson's disease. The severely debilitating and progressive neurodegenerative disease, as of now, has no cure, and this breakthrough could help hundreds of thousands of patients with the condition feel experts.

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.
