[38]). Specific HC10 staining was also seen in the colon (see Fig. 6 in Ref. [38]). HD6 stained small and large bowel tissues of B27 TG1 rats with M.tb-induced arthritis and spondylitis (see Fig. 7 in Ref. [38]). Thus NC-B27 are expressed in gut tissue in B27 TG1 rats. Here, MRAP is linked to arthritic joint disease.
