Using Desert Hedgehog signals to protect and repair salivary glands after radiation

Salivary gland response to Desert hedgehog signaling as an antidote to damage from therapeutic radiation

NIH-funded research Stanford University · NIH-11261536

What this research studies

From a patient's perspective, researchers are studying how support cells around saliva-making glands help those glands recover after radiation. They use mouse models and genetic tracing to follow which cells respond, and single-cell gene readings to see which signals turn on during repair. The team focuses on a specific signal, Desert Hedgehog, that may tell the gland to heal or preserve function. The lab work aims to point toward treatments that could be tested in people in the future.

Who could benefit from this research

Good fit: Adults who received radiation to the head or neck and have chronic dry mouth from salivary gland damage would be the main group likely to benefit or be eligible for future trials.

Not a fit: People whose dry mouth is caused by medications, aging alone, or conditions unrelated to radiation-induced salivary gland damage may not benefit from this specific approach.

Why it matters

Potential benefit: If successful, this work could lead to therapies that prevent or reverse radiation-caused dry mouth, improving swallowing, taste, dental health, and quality of life.

How similar studies have performed: Some preclinical studies have shown Hedgehog pathway signals can aid tissue repair, but using Desert Hedgehog specifically for radiation-damaged salivary glands is relatively new and remains experimental.
