Figure 1

Semiquantitative analysis of dendritic cell subsets in minor salivary glands (MSG) of patients with Sjögren’s syndrome (SjS), focal lymphocytic sialoadenitis (FLS), and keratoconjunctivitis sicca (KCS), as well as in those of control subjects (CTRL). In MSG of patients with SjS and FLS, a distinction was made between positively staining cells located in the parenchyma (P) and those in the lymphocytic infiltrate (I). The number of MSG studied is shown in parentheses for each condition. The following grading system was used: 0, no positive cells; 1, 1–5 positive cells per 0.625 mm2; 2, 6–30 positive cells per 0.625 mm2; 3, 30–100 positive cells per 0.625 mm2. See Table 2 for the specificity of the monoclonal antibodies.
