TYK2 and immune signals that damage salivary glands in Sjögren’s

Tyk2 and Associated Cytokines in Salivary Gland Autoimmunity

NIH-funded research University of Iowa · NIH-11299524

This project looks at how the protein TYK2 and certain immune signals cause salivary gland inflammation that leads to dry mouth and eye problems in people with Sjögren’s.

What this research studies

Researchers will use a mouse model that develops Sjögren’s-like salivary gland inflammation to study how turning off the TYK2 gene changes immune cells in the glands. They will use gene-editing and adoptive-transfer experiments to identify which innate immune cell types and which cytokines (including IL-12 and IL-23) require TYK2 signaling to start disease. The team will compare mouse findings with human genetic links to TYK2 to help translate the results to people. The goal is to uncover early immune triggers that could become targets for earlier diagnosis or therapies that prevent gland damage.

Who could benefit from this research

Good fit: People with Sjögren’s disease or those with early symptoms of dry mouth or dry eye—especially if they carry TYK2-related genetic variants—would be most relevant to follow this work or join related future studies.

Not a fit: People without autoimmune dry mouth or those needing immediate symptom relief are unlikely to benefit directly from this basic laboratory research in the short term.

Why it matters

Potential benefit: If successful, this could point to new targets for early diagnosis or treatments that prevent salivary gland damage and reduce dry mouth and eye complications.

How similar studies have performed: TYK2-targeting therapies have shown benefit in other autoimmune diseases, but applying TYK2-focused approaches specifically to Sjögren’s is relatively new and mainly based on preclinical data.
