چکیده انگلیسی
Brucellosis is one of the most important and widespread zoonosis worldwide responsible for serious economic losses and considerable public health burden. In this study, we investigated the modulatory effect of a microtubule-inhibitor, nocodazole, on B. abortus infection in murine macrophages and in a mouse model. Nocodazole activated macrophages and directly inhibited the growth of Brucella in a dose-dependent manner. Nocodazole increased adhesion but reduced invasion and intracellular growth of Brucella in macrophages although it did not affect co-localization of Brucella with LAMP-1. In addition, nocodazole negatively affected actin polymerization, and weakly activated ERK and p38α but significantly activated JNK in non-infected cells. After subsequent infection, nocodazole weakly inhibited activation of ERK and p38α. For the in vivo tests, nocodazole -treated mice displayed elevated levels of IFN-γ, MCP-1 and IL-10 while Brucella-infected nocodazole -treated mice showed high levels of TNF, IFN-γ, MCP-1, IL-10 and IL-6 as compared to controls. Furthermore, nocodazole treatment reduced inflammation and Brucella proliferation in the spleens of mice. These findings highlight the potential use of nocodazole for the control of brucellosis although further investigations are encouraged to validate its therapeutic use in animal hosts.
