The authors would like to correct Figs 3, 5 and 6. In Fig 3, an error was introduced during the preparation of the figure for publication. Images from the brain of a mouse presented in Fig 4A were inserted into Fig 3A. The corrected version of Fig 3, containing pictures of a correct and representative JH-/- mouse that had been exposed to prion infectivity containing aerosols, can be seen here. The authors also wish to clarify that the original blots for Figs 5E and 6D contained redundant lanes which they had removed from the images while preparing the figures. The authors now provide corrected versions of Figs 5E and 6D with appropriate marks showing the removal of the redundant lane. The uncropped original blots for Figs 5E and 6D are shown as supporting information in S1 File (for Fig 5E) and S2 File (for Fig 6D). The corrected versions of Figs 3, 5 and 6 and the original uncropped blots for Figs 5E and 6D can be viewed below. The authors confirm that these changes do not alter their findings.
