Lifelong Evolution of Autoreactive Plasma Cell Numbers, Affinity, and Anatomic Location in Arthritic K/BxN Mice

Arthritis &Rheumatology, EarlyView.
Objective The spontaneous K/BxN mouse model of rheumatoid arthritis has been used extensively to study chronic inflammation, contribution of immune cells, and the primordial role of autoreactive antibodies in disease initiation and severity. Only the ubiquitous enzyme glucose‐6‐phosphate isomerase (GPI) is the target of IgG autoantibodies secreted by ...
