Rotavirus triple-layered particles. Rotavirus virions are triple-layered particles with icosahedral symmetry. The spike protein and the glycoprotein VP7 compose the external layer. Meanwhile, a unique component, VP6, is part of the middle layer. The VP2 icosahedral internal layer or virus core encapsidates the eleven dsRNA genome segments. All twelve vertices of inner core contain VP1-VP3 complexes. The image represents high-definition transmission electron microscopy of rotavirus triple-layered particles purified from cell culture. After glutaraldehyde fixation, the particles were stained phosphotungstate. Acquired images were colored using Adobe Photoshop.

Rhinovirus C15 (RV-C15) infection of well-differentiated human bronchial epithelial cells cultured in air-liquid interface (hBEC-ALI) fixed at 12h post-infection (p.i.). A total of 50 μL of inoculum (PBS, left; or 1012 copies of RNA of RV-C15, right) was added onto the top of hBEC and incubated at 34C. The inoculum was removed 4 h p.i., and the cells were fixed at 12h p.i. with 4% paraformaldehyde. The indirect immunofluorescence assay was done using antibody against acetylated alpha-tubulin to detect motile cilia (#ab24610, Abcam; green-colored) and against dsRNA to detect the replicative intermediary forms of RV-C15 (#10010200, Scicons; red-colored); while the nuclei were stained with Hoechst 33342 (#H3570, Molecular Probes; blue-colored). The images were acquired using confocal microscopy (LSM710, Carl Zeiss Microscopy) at 630x magnification (scale bar = 10 μM). Courtesy of Talita Gagliardi, University of Maryland, College Park.
