Figure 6.

Clara cells express components of the regulated exocytic machinery. Airways from unchallenged mice were labeled immunohistochemically for expression of Rab3 isoforms (red) and for CCSP (green). Top. Rab3A (red) localizes to the basolateral surfaces of the cells located in a neuroendocrine body (NEB). Middle. Rab3B in the bronchial airways localizes to CCSP expressing Clara cells (yellow in merged image) and is also found cells that do not contain CCSP (red in merged image). Bottom. In the bronchial airways, Rab3D is expressed only by Clara cells (yellow in merged image). Scale bar represents 50 μm (top row) and 100 μm (middle and bottom rows). Data are representative of experiments performed in 3 animals.
