Sjogren's Syndrome as a disorder of anti-receptor autoimmunity

Funded Activity Summary

A new approach to understanding Sjogren's syndrome Sjogren's syndrome (SS) is a frequent cause of illness predominantly in women, leading to frequent attendances to medical, dental and allied health practitioners. Historically considered a rarity, SS, in both its primary and secondary forms, is arguably the commonest manifestation of human systemic autoimmunity. Increasingly recognised by clinicians as the unifying diagnosis underlying a plethora of chronic disabling symptoms in women from the fourth decade and beyond, therapeutic options remain limited due to our primitive understanding of its cause. Emerging evidence suggests that rather than a consequence of physical destruction of salivary and tear glands by cells of the immune system, severe dryness of the mouth and eyes in SS might be caused by antibodies which block the transmission of signals from tiny nerves to receptors in these glands. We also have evidence that other symptoms experienced by patients with SS, including abnormal sweating, irritable bladder and bowel, and Raynaud's phenomenon, may also be the consequence of blockage of nerve supply. Furthermore, we have detected these blocking antibodies in patients with both primary SS and rheumatoid arthritis accompanied by secondary SS, pointing for the first time to a common underlying cause for SS in these two settings. We propose a new approach to understanding Sjogren's syndrome, as a disease of anti-receptor autoimmunity, akin to Graves disease of the thyroid gland. This opens up exciting possibilities for the development of new techniques for the diagnosis and treatment of SS.
