MOVIE?S1? 3D model of a reovirus inclusion visualized by electron tomography (related to Fig.?3). The 3D model was constructed using e-tomo and a combination of masking, isosurface, and manual tracing with Amira segmentation tools. Black spots represent gold particles used as fiducials. The computational slices of the tomogram are first swept upwards (first third of the movie) and then backwards (second third), revealing the 3D isosurface representation. The last third of the movie rotates the 3D representation. ER, light yellow; viral particles, light blue; nuclear membrane, dark blue; mitochondria, red; membrane fragments, brown; Rabbit polyclonal to NF-kappaB p65.NFKB1 (MIM 164011) or NFKB2 (MIM 164012) is bound to REL (MIM 164910), RELA, or RELB (MIM 604758) to form the NFKB complex.The p50 (NFKB1)/p65 (RELA) heterodimer is the most abundant form of NFKB. vesicles, orange.

Live-cell imaging of reovirus contamination demonstrates altered ER morphology in U-2 OS cells. U-2 OS cells designed to stably express mCherry-KDEL were transfected with an N-terminally tagged GFP construct expressing residues 1 to 230 of the NS protein. Cells were adsorbed with reovirus T1L ZM 306416 hydrochloride at an MOI of 10,000?PFU/cell and imaged every 30?min from 9 to 18?h postinfection.
