This project aims to see if getting rid of aged 'senescent' cells can help salivary glands work better for people with Sjögren's.

What this research studies
Researchers have found aged, or 'senescent,' cells in the salivary glands of people with Sjögren's and in mouse models of the disease. They will examine how these senescent cells affect salivary gland stem cells and overall saliva production by analyzing human gland tissue and using mouse experiments. The team will test drugs called senolytics in mouse models to see whether removing senescent cells reduces gland damage and improves saliva flow. Results are intended to point toward treatments that could later be tested in people.
Who could benefit from this research
Good fit: People diagnosed with Sjögren's syndrome who have dry mouth and reduced saliva production would be the likely candidates for related future trials.
Not a fit: People without Sjögren's or those whose salivary glands are already permanently scarred are less likely to benefit from this approach.
Why it matters
Potential benefit: If successful, this work could lead to treatments that restore saliva production and relieve dry mouth symptoms in Sjögren's patients.
How similar studies have performed: Early animal work showed senolytic drugs reduced senescent cells and improved saliva in a mouse model, but applying this approach in humans is still new.
