ABSTRACT
Sjögrens syndrome is an autoimmune exocrinopathy, mainly affecting the lacrimal and salivary glands, and resulting in ocular and oral dryness (keratoconjunctivitis sicca and xerostomia). The aetiology and pathogenesis are largely unknown, and only palliative treatment is currently available. Data obtained from experimental animal and human studies using biological agents or gene therapeutics can offer insight into the disease process of Sjögrens syndrome. This article reviews the current literature on these approaches and assesses the lessons learnt about the pathogenesis of Sjögrens syndrome.
