Figure 6. Alignment of T cell receptor β sequences from expanded salivary gland clones and closely related unique cells.

Cluster designations match those in Figure 4. Subject designations indicate expanded clones and match designations in Table 3 and Figure 3. Sequences that are part of clonal expansions (Exp) are indicated by “+,” and unique sequences are indicated as “–.” Underlined residues are derived from the NDN-region. Nonunderlined residues are derived from germline sequence. Gray shading indicates similar or identical residues derived from germline sequence. Blue shading indicates similar or identical residues derived from the NDN-region. Ro and La antibody status of each subject is listed as positive (+) or negative (–).
