Ion of pIgR and nuclei in lungs of mock-treated and infected mice. Total magnification 630X. Data S1 Three-dimensional visualization of S. pneumoniae and pIgR inside the subarachnoid space of infected mice detected by confocal microscopy. Acknowledgments A part of the operate was performed in the UMCG Microscopy and Imaging Center. We thank Henk Moorlag from the UMCG Endothelial Cell Facility for delivering HUVEC and for cryostat cutting of tissue sections. We also thank Dr. Henrik Gradstedt for giving the antipneumococcal antiserum and Prof. dr. Jan Maarten van Dijl for the comments on the manuscript.
