Fig. 1From: Interaction of biomedical nanoparticles with the pulmonary immune systemInteractions of DCs and T cells in the airway mucosa visualized by laser scanning microscopy. Micrograph shows a scanned area from a cross section through a trachea (rat). T cells (CD3, blue) are visible closely interacting with DCs (MHC class II, green) inside the airway epithelium (EP) and the lamina propria (LP)Back to article page
