Necrostatin-1s (NST-1s) inhibits development of rheumatoid arthritis (RA) in the collagen-induced arthritis (CIA) mouse model. a Reduction in arthritis score and arthritis incidence in CIA mice treated with NST-1s. CIA mice were injected intraperitoneally (i.p.) with NST-1s (300 µg/kg) once daily for 14 weeks after CIA induction. b Representative results of the effects of NST-1s on RA development in CIA mice. Tissue specimens obtained from the hind paw joints of each group of mice at the end point of the experiment were analyzed by staining with hematoxylin and eosin (H&E) and Safranin O. *p < 0.05; **p < 0.01; ***p < 0.001
