HAdV-F41 Interferes with Cell Surface Expression of MIC B We examined if HAdV-F41 impairs the cell surface expression of MIC A and MIC We examined if flow cytometry and IF. We first expression from the A and MIC B B in HCT116 cells by HAdV-F41 impairs the cell surfacecharacterized MICbasal expression in HCT116 cells by flow uninfected and IF. We initial characterized the basal show that for levels of MIC ligands in cytometry HCT116 cells more than four days. NPY Y2 receptor Agonist Biological Activity Results expression levels of A and MIC in uninfected HCT116 greater intracellularly than around the that for each MIC MIC ligandsB, expression levels are cells over 4 days. Results showcell surface both MIC A and MIC B, expression additional abundant general than than on the cell 3a,b), and (Figure 3a). Additionally, MIC B islevels are greater intracellularlyMIC A (Figure surface (Figure negligibly expressed B is far more abundant all round than MIC it’s important and MIC A is3a). Moreover, MIC on HCT116 cells (Figure 3a). Lastly, A (Figure 3a,b), to note MIC A is negligibly expressed on that, in uninfected HCT116 cells, HCT116cell surface expression levels decreased slightly MIC B cells (Figure 3a). Finally, it is important to note that, in uninfected HCT116 cells, MIC B cell surface expression levels decreased slightly from day two to day four (Figure 3a). This may be on account of the proteolytic shedding of MIC B from from day two to day four (Figure 3a). This may be as a result of the proteolytic shedding of MIC B the cell surface, a course of action that occurs for the duration of typical cell development as well as the expression of MIC in the cell surface, a p38 MAPK Agonist Species approach that happens through standard cell growth as well as the expression proteins [39]. of MIC proteins [39].Figure three.

Cells were harvested at day and MIC B onon the surface andin the intracellular environment of uninfected HCT116 cells. Cells have been harvested at day two and 4 in culture. Isotype Abs suggested by the manufacturer were applied as damaging controls. Sample had been analyzed two and four in culture. Isotype Abs advised by the manufacturer had been applied as negative controls. Sample had been analyzed on a Gallios (Beckman Coulter, Brea, CA, USA) flow.
