Objective : systemic sclerosis (SSc) is an autoimmune immune disease, pathology mainly composed of three components: fibrosis, vascular disease, and autoimmune abnormalities
.
This study is to explore the effect of B cell depletion on SSc fibrosis and its mechanism
ObjectiveObjective : systemic sclerosis (SSc) is an autoimmune immune disease, pathology mainly composed of three components: fibrosis, vascular disease, and autoimmune abnormalities
Methods : Bleomycin-induced SSc (BLM-SSc) mice were treated with anti- CD20 antibody , and histopathological evaluation of skin and lung fibrosis was performed .
T cells and macrophages were co-cultured with B cells, and the influence of B cells on their differentiation was evaluated by flow cytometry .
MethodMethod : with an anti- CD20 antibody therapy bleomycin-induced SSc (BLM-SSc) in mice, and skin fibrosis and pulmonary histopathological evaluation
B cell depletion inhibited fibrosis in BLM-SSc mice
Conclusion These findings indicate that B cell depletion inhibits tissue fibrosis by inhibiting the differentiation of pro-fibrotic macrophages in BLM-SSc mice, providing a new theoretical basis for the treatment of B cell depletion in SSc .
