Scientists have recreated the growth of Lewy bodies in human neurons and followed their formation to gain important insight into why and how they form. Critically, they find that immune challenge is important for this process, identifying a previously unknown link between the immune system and neurological disease.
A research team has revealed that a molecule in the brain -- ophthalmic acid -- unexpectedly acts like a neurotransmitter similar to dopamine in regulating motor function, offering a new therapeutic target for Parkinson's and other movement diseases.
Parkinson's disease, a debilitating nervous system disorder, is treated with medications that sometimes cause impaired decision-making and poor impulse control. Now, researchers have identified a structure in the brain called the external globus pallidus which may be responsible for this side effect, paving the way for new treatments.
