摘要: Using morphologic and ultrastructural criteria, the present study in rat was undertaken to distinguish lymphoepithelial nodules from lymphoid aggregates lymph nodes, demonstrate uptake transport of ferritin latex particles, instilled trachea, by lymphoepithelium. Unlike nodes or aggregates, can be distinguished following characteristics lymphoepithelium: it is flattened devoid goblet cells; contains intracellular “intercellular” vacuoles; occasional macrophage-like cells infiltrates surrounding lymphocytes clusters observed. At any time, no particle found inside under lymphoepithelium, but until 1 hour after local instillation, particles were localized close cilia, at luminal surface epithelium, within vesicles some cells, intercellular space. Moreover, consistently on both sides ...
