Rheumatoid arthritis (RA) is a chronic autoimmune disease that affects millions of individuals worldwide. This debilitating condition primarily targets the joints, causing pain, swelling, morning stiffness, and irreversible damage if left uncontrolled.
Adjuvant-induced HSC-NCG-M
Human hematopoietic stem cells (HSCs) were infused into NCG-M (strain No.T036669) mice, the immune-deficient mice, to reconstitute human immune cell population, followed by administration of CFA to induce arthritis.
Arthritis score
CFA administration caused paw swelling and increased the arthritis score.
Immune cell population in synovial fluid
Expansion of T cells and myeloid cells in CFA induced immune reconstitution arthritis model.
Pathohistological study
Articular inflammation, bone erosion and proteoglycans damage were observed in arthritis model.
Drug efficacy studies
Adalimumab significantly alleviated the claw swelling, while tocilizumab exhibited no obvious efficacy.
