Mouse anti Bovine CD8 antibody, clone CC63 used for the identification of CD8 expressing cells in the bovine nasopharynx by immunofluorescence.
**Image caption:**
Nasopharyngeal primary infection sites of vaccinated cattle are infiltrated by CD8+/CD3- (presumptive NK) cells at 24 hpi.
Multichannel immunofluorescent technique. A). FMDV VP1 (red) protein within cytokeratin+ cells (green) in epithelial crypt of the nasopharyngeal mucosa of non-vaccinated steer at 24 hpi (animal number 3). CD8+ (aqua)/ CD3+ (purple) double-positive CTLs are present in the subepithelial compartment amongst larger populations of CD8-/CD3+ T-lymphocytes. 20x magnification, scale bar 50μm. B) 40x magnification of region identified in (A), demonstrating consistent co-localization of CD8 (aqua) with CD3 (purple). Scale bars 25μm. B) Select channels of image shown in (B). CD3+ cells (purple) include single-positive (T-lymphocytes) or CD8+/CD3+ double-positive (CTLs). CD8 (aqua) is exclusively detected in combination with CD3 (purple). Scale bars 25 μm. D) FMDV VP1 (red) protein co-localize with cytokeratin (green) in a focal surface erosion within follicle-associated epithelium of nasopharyngeal mucosa of vaccinated steer at 24 hpi (animal number 11). A distinct population of cells defined as presumptive NK-cells based on a CD8+ (aqua)/CD3- (purple) phenotype is present in submucosal and epithelial compartments surrounding the focus of infection. A smaller population of CTLs (CD8+/CD3+) is present amongst abundant non-CTL T-lymphocytes (CD8-/CD3+). 20x magnification, scale bar 50μm. E) Higher magnification of region identified in showing CD8+/CD3- cells (aqua) representing presumptive NK cells in close proximity of FMDV infected focus. 40x magnification, scale bars 25 μm F) Individual channels of image shown in (E) demonstrating inconsistent co-localization of CD8 (aqua) and CD3 (purple).
