    TLR7 and TLR9 are crucial mediators of autoimmunity in systemic lupus erythematosus (SLE) and Sjögren’s syndrome (SjD).

  • 2

    Both SLE and SjD exhibit heightened TLR7 and TLR9 signaling, contributing to chronic inflammation and immune dysfunction.

  • 3

    SLE is characterized by diverse organ involvement and is predominantly diagnosed in women, particularly those of African descent.

  • 4

    Genetic studies link TLR7 and TLR9 polymorphisms to increased susceptibility to SLE, highlighting their roles in disease pathogenesis.

  • 5

    Current therapies targeting TLR pathways are being explored for their potential effectiveness in treating SLE and SjD.
