Dickkopf-1 (DKK-1) is mostly known as a mature inhibitor of classic Wnt signaling pathways, which plays a critically role in regulating bone formation and bone metastasis. In recent years, the roles of DKK-1 played in bone resorption, bone formation, immune homeostasis and inflammation have been investigated. The role of DKK-1 in the pathogenesis and treatment of autoimmune diseases (ADs), including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), etc, has attracted widespread attention. Various studies have found that DKK-1 may be used as a biomarker for the occurrence and development of ADs, and as a potential target for the treatment of ADs. In this review, we have briefly summed up the intricate immunological functions and regulatory mechanisms of DKK-1 in ADs, aiming to further learning more about the role of DKK-1 involved in the pathogenesis of ADs and provide an outlook for the potential future researches.

Delivering protein drugs to the central nervous system (CNS) is challenging due to the blood-brain and blood-spinal cord barrier. Here we show that neutrophils, which naturally migrate through these barriers to inflamed CNS sites and release neutrophil extracellular traps (NETs), can be leveraged for therapeutic delivery. Tannic acid nanoparticles tethered with anti-Ly6G antibody and interferon-β (aLy6G-IFNβ@TLP) are constructed for targeted neutrophil delivery.

Dysregulated IL-10 producing regulatory B cells (Bregs) are associated with the progression of systemic lupus erythematosus. An immunomodulatory role of heat shock proteins (HSPs) is implicated in autoimmune diseases. However, the molecular basis underlying the role of Hspa13 in regulating Bregs function and lupus pathogenesis remains unclear.
