We previously demonstrated that the programmed death_1 (PD_\u003c-1\u003e)/PD-ligand _1 (PD-L_1) pathway is involved in immune dysfunction during M. bovis infection and that prostaglandin E_2 (PGE_2) suppressed immune responses and upregulated PD-L_1 expression in Johne\u0027s disease, a bacterial infection in cattle. In this study, we investigated the role of PGE_2 in immune dysfunction and the relationship between PGE_2 and the PD-1/PD-L1 pathway in M. bovis infection. In vitro stimulation with M. bovis upregulated the expressions of PGE_2 and PD-L_1 presumably via Toll-like receptor 2 in bovine peripheral blood mononuclear cells (PBMCs). PGE_2 levels of peripheral blood in infected cattle were significantly increased compared with those in uninfected cattle. Remarkably, plasma PGE_2 levels were positively correlated with the proportions of PD-L_1^+ monocytes in M. bovis-infected cattle. Additionally, plasma PGE_2 production in infected cattle was negatively correlated with M. bovis-specific interferon (IFN)-γ production from PBMCs. These results suggest that PGE_2 could be one of the inducers of PD-L1 expression and could be involved in immunosuppression during M. bovis infection. In vitro blockade assays using anti-bovine PD-L_1 antibody and a cyclooxygenase 2 inhibitor significantly upregulated the M. bovis-specific IFN-γ response. Our study findings might contribute to the development of novel therapeutic strategies for bovine mycoplasmosis that target PGE_2 and the PD_\u003c-1\u003e/PD-L_1 pathway.",

内容記述 | Bovine mycoplasmosis caused by Mycoplasma bovis results in pneumonia and mastitis in cattle. We previously demonstrated that the programmed death_1 (PD_<-1>)/PD-ligand _1 (PD-L_1) pathway is involved in immune dysfunction during M. bovis infection and that prostaglandin E_2 (PGE_2) suppressed immune responses and upregulated PD-L_1 expression in Johne's disease, a bacterial infection in cattle. In this study, we investigated the role of PGE_2 in immune dysfunction and the relationship between PGE_2 and the PD-1/PD-L1 pathway in M. bovis infection. In vitro stimulation with M. bovis upregulated the expressions of PGE_2 and PD-L_1 presumably via Toll-like receptor 2 in bovine peripheral blood mononuclear cells (PBMCs). PGE_2 levels of peripheral blood in infected cattle were significantly increased compared with those in uninfected cattle. Remarkably, plasma PGE_2 levels were positively correlated with the proportions of PD-L_1^+ monocytes in M. bovis-infected cattle. Additionally, plasma PGE_2 production in infected cattle was negatively correlated with M. bovis-specific interferon (IFN)-γ production from PBMCs. These results suggest that PGE_2 could be one of the inducers of PD-L1 expression and could be involved in immunosuppression during M. bovis infection. In vitro blockade assays using anti-bovine PD-L_1 antibody and a cyclooxygenase 2 inhibitor significantly upregulated the M. bovis-specific IFN-γ response. Our study findings might contribute to the development of novel therapeutic strategies for bovine mycoplasmosis that target PGE_2 and the PD_<-1>/PD-L_1 pathway. | |||||
