recombinant expression of functional and nonfunctional forms of bovine granzyme B in COS-7 cells. Establishment of an enzymatic assay to detect and quantify the expression of functional granzyme B protein. Using this assay, the levels of killing of different Theileria parva-specific CD8+ T-cell clones are found to be significantly correlated with the levels of granzyme B protein but not the levels of mRNA transcript expression | Bos taurus |

additional information | establishment of an enzymatic assay to detect and quantify the expression of functional granzyme B protein. Using this assay, the levels of killing of different Theileria parva-specific CD8+ T-cell clones are found to be significantly correlated with the levels of granzyme B protein but not the levels of mRNA transcript expression. Using inhibitors specific for perforin and granzyme B confirms that CD8+ T-cell killing of parasitized cells is dependent on granule exocytosis and, specifically, granzyme B | Bos taurus |
physiological function | cytotoxic CD8+ T-cells are important mediators of immunity against the bovine intracellular protozoan parasite Theileria parva. Granzyme B is an essential mediator in CD8 T-cell killing of Theileria parva-infected cells. CD8+ T-cell killing of parasitized cells is dependent on granule exocytosis and, specifically, granzyme B. The granzyme B-mediated death of parasitized cells is independent of caspases. Granzyme B activates the proapoptotic molecule Bid. The cytotoxic activity of T-cells is not dependent on caspases but is associated with activation of Bid | Bos taurus |
