Brain Protein in Mice Offers Insights Into Brain Development and ADHD
Researchers identified a brain protein, NSF, that is important for maintaining dopamine-related cells and normal development, providing new insights into ADHD and potential therapeutic strategies.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by excessive activity and impulsivity, often beginning in childhood. The mechanisms behind ADHD are not fully understood, though changes in the brain's dopamine system have been linked to the disorder. Researchers at the University of Fukui have discovered that a protein called N-ethylmaleimide-sensitive factor (NSF) linked to dopamine receptors may contribute to ADHD-like behaviors in mice.
The study, led by assistant professor Min-Jue Xie, focused on genetically modified mice with a conditional knockout of NSF in D2 receptor-expressing cells. These mice exhibited lower dopamine levels, impaired striatal development, and ADHD-like behaviors, such as hyperactivity and impulsivity. The team also found that combining methylphenidate, a commonly used ADHD medication, with quinpirole, a drug that activates D2R, alleviated the mice's hyperactivity and impulsivity, suggesting a potential complementary treatment strategy.
While this research is still in its early stages and does not immediately lead to new treatments, it offers valuable insights into the role of NSF in dopamine-related brain cells and may help inform future therapeutic approaches for ADHD.
