Anti-Argonaute Antibodies for the Diagnosis of Sensory Neuronopathies

Argonaute (AGO) proteins have been described as the target of antibodies in several autoimmune diseases including Sjögren Syndrome (SS). Sensory neuronopathies (SNN) are disorders affecting neurons in the dorsal root ganglia that may depend on an inflammatory process. However, identifying these cases needs the availability of specific biomarkers. The aim of this study is to test the prevalence of anti-AGO antibodies in a population of patients with Sensory neuronopathies (SNN) with and without associated autoimmune disease in comparison with other peripheral neuropathies to determine how anti-AGO antibodies may help the identification of potentially dysimmune Sensory neuronopathies (SNN).
