Outline of Final Research Achievements

Although there are many malignant infectious diseases in livestock involving immune abnormalities (impairments), the mechanisms underlying these diseases remain unknown. In this research, we analyzed the mechanism of immune abnormalities in the malignant infectious diseases associated with economic loss in livestock industry, such as bovine anaplasmosis, East Coast fever, Surra, bovine tuberculosis, Johne’s disease, bovine leukemia, Equine infectious anemia. Our analyses have shown that immunosuppressive factors, such as Programmed death 1 (PD-1) and Programmed death-ligand 1 (PD-L1), are involved in immune suppression seen in the malignant infectious diseases. Furthermore, in vitro blockade of the PD-1/PD-L1 pathway restored anti-pathogen-specific T-cell proliferation and cytokine production.
