    While indirect evidence supports enhanced Toll -like receptor 7 (TLR7) signaling as a mechanism in human systemic autoimmune disease, evidence that TLR7 gene variants contribute to lupus is lackin.

    TLR7 is a sensor of viral RNA that binds to guanosin.

    This study identifies that TLR7 gain-of-function mutations can cause B cell-driven autoimmunity, including SLE , because of increased affinity for guanosine, resulting in a lower threshold for TLR7 activatio.
