Protecting salivary glands from irradiation damage
Each year, more than 500,000 patients worldwide are treated for head and neck cancer External link. The current standard of care involves exposure to radiation that can damage salivary glands, leading to permanent dry mouth (xerostomia) that negatively affects oral health and overall quality of life.
IRP scientists led by Matthew Hoffman, B.D.S., Ph.D., showed that treating irradiated mouse fetal salivary gland tissues with the neurotrophic protein neurturin to restore parasympathetic function improves salivary gland regeneration.
The findings provide a new target and research direction for how salivary glands (and other sensitive organs) may be protected or regenerated in people undergoing extensive treatment for cancers.
