What is Sjogren Syndrome

Sjogren Syndrome is a chronic, systemic autoimmune disorder characterized by the immune-mediated destruction of exocrine glands, primarily the salivary and lacrimal glands. The disease arises from a combination of genetic predisposition, environmental triggers, and dysregulated immune responses, leading to the activation of autoreactive T and B lymphocytes. This process results in the production of autoantibodies, such as anti-SSA/Ro and anti-SSB/La, and cytokine-driven tissue injury, ultimately causing glandular dysfunction. Sjogren Syndrome may occur as a primary condition or in association with other autoimmune diseases, such as rheumatoid arthritis or systemic lupus erythematosus. Clinically, Sjogren Syndrome most commonly presents with persistent dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca), but can also involve systemic features like fatigue, arthralgia, and an increased risk of non-Hodgkin lymphoma. Diagnosis is based on a combination of symptoms, objective tests for glandular function (e.g., Schirmer’s test, salivary flow measurement), serological markers (anti-SSA/Ro, anti-SSB/La), and confirmatory minor salivary gland biopsy. Treatment focuses on symptomatic relief and includes muscarinic agonists such as cevimeline and pilocarpine to stimulate glandular secretion, as well as sialogogues like anethole trithione. Management also addresses complications and monitors for systemic involvement.

Targets for Sjogren Syndrome

Targets in Clinical or Later Phases of Development

Target Name Gene Symbol
Muscarinic Acetylcholine Receptor (mAChR) (nonspecified subtype)
CD80 molecule CD80
CD40 ligand CD40LG
CD86 molecule CD86
Fc gamma receptor and transporter FCGRT
TNF superfamily member 13 TNFSF13
TNF superfamily member 13b TNFSF13B
tyrosine kinase 2 TYK2
TNF receptor superfamily member 13C TNFRSF13C
phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta PIK3CD

Key therapeutic targets in Sjogren syndrome (SS) are central to the dysregulated immune pathways underlying the disease. B cell activation and survival are driven by molecules such as Bruton Tyrosine Kinase (BTK), Spleen Associated Tyrosine Kinase (SYK), and Phosphatidylinositol-4,5-bisphosphate 3-kinase delta (PIK3CD), which amplify B cell receptor signaling, promote autoantibody production, and sustain lymphocytic infiltration of exocrine glands. Additional targets like TNFSF13B (BAFF), TNFSF13 (APRIL), and their receptor TNFRSF13C (BAFF-R) are crucial for B cell survival and are upregulated in SS. T cell co-stimulatory molecules, including CD40, CD40LG, CD80, and CD86, facilitate aberrant T-B cell interactions and germinal center formation. Cytokine signaling components such as TYK2 and JAK2 further perpetuate inflammation via the JAK/STAT pathway. Innate immune receptors like TLR7 and TLR8 initiate type I interferon responses, while FCGRT modulates IgG handling and immune complex persistence. These molecular targets offer multiple avenues for therapeutic intervention. BTK, SYK, and PI3Kδ inhibitors, as well as BAFF antagonists, are in various stages of clinical development or approved for related autoimmune conditions, with promising preclinical and translational data in SS. Blockade of T cell co-stimulatory pathways using agents like abatacept (CTLA4-Ig) and anti-CD40LG antibodies is under investigation to disrupt pathological immune cell crosstalk. JAK inhibitors, including baricitinib, target cytokine-driven inflammation and are being evaluated in clinical trials. Modulation of innate immune sensors (e.g., TLR7 antagonists) and FcRn-mediated IgG recycling represents additional emerging strategies. Collectively, these targets not only deepen understanding of SS pathogenesis but also inform the rational design of novel, mechanism-based therapies.
