Key takeaways

  • •A new therapy targets a specific protein called SLC6A20 to improve brain cell communication.
  • •The treatment successfully restored NMDA receptor function, which is often low in certain types of autism.
  • •A single dose remained effective for at least 8 weeks in animal models without causing harmful side effects.

Plain-language summary

Scientists are testing a new way to help the brain communicate better in people with genetic forms of autism. In this study, they used 'antisense therapy'—a way to turn certain genes on or off—to target a transporter protein in the brain.

This helped fix a specific type of signal (NMDA receptors) that doesn't work correctly in children with SHANK2 or SHANK3 gene changes. The results were seen in both mice and human brain cells grown in a lab.

How it works

Science explained

This new approach uses 'antisense therapy' to adjust how certain genes work. Specifically, it targets a transporter protein called SLC6A20 in the brain. By doing this, the therapy helps to fix problems with NMDA receptors, which are crucial for brain cell communication and often don't function correctly in certain types of autism.

Why parents may care

This research identifies a specific target for future medicines that could potentially help with learning and social challenges in children who have SHANK-related autism.

What this means for daily life

This research suggests a potential path for future medicines that could specifically help address learning and social challenges in children with autism linked to SHANK gene changes. By improving brain signaling, the goal is to enhance the child's daily functioning.

What is still unknown

We do not know if this therapy will be safe or work the same way in living human children, as it has only been tested in animals and lab-grown cells.

Frequently asked questions about Autism

Researchers used an 'antisense therapy' to target a specific transporter protein in the brain. This method aims to adjust gene activity to improve brain cell communication, specifically by fixing issues with NMDA receptors that are often found in certain genetic forms of autism.

Terminology glossary

Antisense therapy
A method used to turn specific genes on or off, helping to control the production of certain proteins.
NMDA receptors
Specific types of signal receivers on brain cells that are important for learning and memory, which can be underactive in some forms of autism.
SHANK2/SHANK3 genes
Genes that, when changed or mutated, can be linked to certain forms of autism and affect how brain cells communicate.
SLC6A20
A specific transporter protein found in the brain that this new therapy targets to improve cell-to-cell communication.
Gene-targeted therapy
A type of medical treatment that specifically focuses on correcting issues caused by particular genes in the body.
Transporter protein
A protein that helps move specific substances, like signaling molecules, across the membranes of cells.

Questions to ask your doctor or therapist

  • ?Is my child's autism linked to a SHANK2 or SHANK3 gene mutation?
  • ?What are NMDA receptors and why are they important for learning?
  • ?How far away are human trials for antisense therapies in autism?
