Abstract: | Activation of Toll-like receptor 7 (TLR7) can induce lupus in mice, whereas activation of TLR9 can prevent it, even though both receptors interact with myeloid differentiation primary response gene 88 (MyD88) for downstream signaling. How TLR9 triggers anti-inflammatory responses in autoimmunity is unclear. Leibler et al. recently reported that TLR9 initiates anti-inflammatory signaling and inhibits lupus pathogenesis in a MyD88-independent but ligand-dependent manner. |
