Fig. 2From: Single-cell RNA sequencing of submandibular gland reveals collagen type XV-positive fibroblasts as a disease-characterizing cell population of IgG4-related diseaseSerum collagen type XV levels are decreased after immune-suppressive therapy in patients with IgG4-RD. (A) The serum collagen type XV levels in healthy individuals (N = 5) and patients with IgG4-RD (N = 5 for inactive and N = 10 for active disease) are displayed. (B) The changes in serum collagen type XV levels before and after immune suppressive treatment in IgG4-RD patients are presentedBack to article page
