Corynebacterium pseudotuberculosis, a broad host-spectrum zoonotic pathogen, causes caseous lymphadenitis (CLA) in small ruminants and is responsible for considerable economic losses in the livestock industry worldwide. Macrophages play a pivotal role in the immunopathogenesis of CLA. However, the immunoregulatory mechanisms of macrophages against C. pseudotuberculosis remains poorly understood. In the present study, for the first time, the partial exoproteome of murine peritoneal macrophages infected with C. pseudotuberculosis was profiled and the differential expression of the identified proteins was analyzed. In macrophages, infection with C. pseudotuberculosis, rather than with heat-killed bacteria, induced release of diverse proteins. Three unconventional proteins: cofilin-1, peroxiredoxin-1, and galectin-3 were significantly expressed and released by infected macrophages into the culture supernatant. These proteins are involved in the host inflammatory response and may be responsible for the excessive inflammation of CLA. In C. pseudotuberculosis-infected macrophages, the release of cofilin-1 and peroxiredoxin-1 was predominant at later stages of infection, while the release of galectin-3 was independent of time. Taken together, the present work contributes to our understanding of the functional role of macrophage response to C. pseudotuberculosis infection.
