Background：To study specifically the immuno-responses and symptoms of arthritis on certain joints, meanwhile minimize the autoimmune responses and its systemic damages, we have established a single-joint arthritis model in NHP.

Model: single-joint arthritis model in NHP

Standard study duration: 4 weeks

Clinical endpoint: joint lavage fluid, Arthritis Score, X-Ray, Pathology

Features: specific localized tests for immune-response, controlled incidence, relapse disease, joint lavage fluid, higher animal welfare and lower overall costs.
