Spontaneous K/BxN arthritis. Nik–/– mice and control littermates were bred to express both the KRN T cell receptor and H-2g7 allele, a combination that leads to severe spontaneous arthritis in wild-type mice, apparent by 5 weeks. (A) Total paw thickness (sum of results for all 4 paws) in Nik+/? and Nik–/– mice at 5 and 11 weeks of age. *P < 0.0002 compared with Nik+/?. (B) Arthritic forepaw from Nik+/+ mouse. (C) Nonarthritic forepaw from Nik–/– mouse. (D) Arthritic hind paw from Nik+/+ mouse. (E) Nonarthritic hind paw from Nik–/– mouse. Magnification, ×40.
