What this research studies

The team will design new molecules intended to prevent the formation of individual synapses between neurons. They will screen these designs in lab tests and cell cultures to find candidates that work. Promising tools will be tested in living Drosophila (fruit fly) brains to block particular connections and observe resulting changes in neural activity and behavior. The work aims to replicate synaptic changes linked to autism and ADHD so scientists can better understand how altered wiring produces symptoms.

Who could benefit from this research

Good fit: People with autism spectrum disorder or ADHD, and their caregivers, may be most interested in following this work because it targets brain wiring changes linked to those conditions.

Not a fit: Patients seeking immediate new treatments should know this is basic laboratory research in fruit flies and is unlikely to offer direct or near-term personal benefit.

Why it matters

Potential benefit: If successful, this could help scientists pinpoint how specific synaptic changes cause symptoms of autism and ADHD and guide the development of more targeted therapies.

How similar studies have performed: Basic research in model organisms has advanced understanding of brain wiring before, but deliberately re-engineering single synapses in living brains is a novel and largely untested approach.
