Loss of TRIM21 drives UVB‐induced systemic inflammation by regulating DNA‐sensing pathways

Arthritis &Rheumatology, Accepted Article.
Background Patients with systemic lupus erythematosus (SLE) experience photosensitivity, with exposure to ultraviolet light B (UVB) driving lupus flares and triggering symptoms like joint pain, fatigue, and cutaneous lesions. Although the mechanism(s) linking UVB exposure to systemic effects are unclear, type I interferons (IFNs) are known to play a ...
