Abstract:
The peanut-agglutinin binding of lymph node follicles was studied in frozen and paraffin sections of human tonsils. In a substantial fraction (10-25%) of follicles focal zones of high PNA receptor expression were encountered which were more readily recognizable in paraffin sections and corresponded to the centrocytous, "light" zone of the follicle. Results suggest that divergent lectin binding of follicles reflects their different functional states.
