FIG. 3.

B and T-cell segregation in LM lymphoid aggregates. (A–C) The lymphoid aggregate shown in Figures 2C and 2D, stained for the B-cell marker CD20 (A), the T-cell marker CD3 (B), and the mature myeloid dendritic cell marker CD83 (C), demonstrating segregation of T and mature myeloid dendritic cells to the periphery of a B-cell zone. (D–F) CD20, CD3, and CD83 staining, respectively, of a large, organized lymphoid aggregate in a persistent microcystic LM of the tongue, showing similar segregation of B-cells (D), T-cells (E), and mature myeloid dendritic cells (F).
