NanoATV within marginal zone macrophages of the spleen.

<p>Confocal microscopy images of cryosectioned spleen collected 12 h after intraperitoneal injection of nanoATV. Immunofluorescence images are as follows: <b>(A)</b> Cell nuclei stained with DAPI (blue); <b>(B)</b> Macrophages stained with CD169 and Alexa Fluor 488 (green); <b>(C)</b> NanoATV labeled with CF633 (pink); <b>(D)</b> Overlay of CD169-labeled macrophages and CF633-labeled nanoATV. Images were acquired with a LSM 710 confocal microscopy at 10x. (scale bars = 100 μm).</p>
