Figure 1From: A systems-based approach to analyse the host response in murine lung macrophages challenged with respiratory syncytial virusLung macrophages are efficiently infected with RSV. (A) (i) PMΦ cells and (ii) AMΦ cells were mock-infected or RSV-infected, and at 24 hrs post-infection (hpi) stained with anti-RSV and examined using fluorescence microscopy (objective x 10) (highlighted by white arrows). (B) Mock (M) and RSV-infected (I) PMΦ cell lysates were examined by immunoblotting using anti-N, anti-P, anti-M2-1, anti-F or anti-G. Anti-actin is shown as the loading control. Analysis of mock and RSV-infected HEp2 cells (using same cell numbers) with anti-F and anti-G is shown. Protein bands of the expected sizes for the respective virus proteins are indicated. The 50 kDa F1 subunit, and the O- and N-linked (G(o/n)) and N-linked (G (n)) glycosylated G proteins are indicated. PMΦ cells were infected with RSV and at 24 hpi the cells were fixed, labelled using (C) anti-F or (D) anti-G and examined using florescence scanning confocal microscopy (FSCM) (i) at a focal plane that shows the cell surface staining (inset, highlighted by *) or (ii) in cross-section showing the surface staining (highlighted by white arrow). (E) The AMΦ cells were stained using anti-F and examined at a focal plane that shows the cell surface (inset, highlighted by *). (F) RSV-infected HEp2 cells at 24 hpi stained using anti-F (inset) and examined using FSCM, the virus filaments (VF) on the cell surface are highlighted. (G) (i) Mock and (ii) RSV-infected cells were stained with anti-RSV and anti-HSP90. The presence of virus-induced inclusion bodies and HSP90 staining of these structures is highlighted (white arrows). (H) RSV-infected AMΦ cells were stained using anti-RSV, and the presence of stained inclusion bodies highlighted (white arrow). (I) At 24 hpi RSV-infected PMΦ cells were stained with anti-RSV and anti-LAMP-1. The inclusion bodies (IB) and the LAMP-1 punctate staining pattern (white arrows) are highlighted.Back to article page
