CD8+tissue-resident memory T cells are expanded in primary Sjögren’s disease and can be therapeutically targeted by CD103 blockade

Tissue-resident memory cells (Trm) are a subset of T cells residing persistently and long-term within specific tissues that contribute to persistent inflammation and tissue damage. We characterised the phenotype and function of Trm and the role of CD103 in primary Sjogren's syndrome (pSS).
