Fig. 4.

Recognition profiles of serum immunoglobulin A (IgA) antibodies against calreticulin (CRT) decapeptides (each overlapping by eight amino acids) in refractory coeliac disease (RCD, n = 12), coeliac disease (CD, n = 14) and healthy controls (n = 14). These profiles are cumulative data (% of sera reactive with individual CRT peptides) relative to each group size and values shown on the right. The synthetic peptides 1–88, 89–143 and 144–201 correspond to N-, P- and C-domains of the CRT molecule.
