Resumen:
The liver is affected in human brucellosis. B. abortus (Ba) triggers on HSC a profibrotic response characterized by inhibition of MMP-9 with concomitant collagen deposition and TGF-β1 secretion in a way that involved a functional T4SS. Taking into account that it has been reported that inflammasome is necessary to induce a fibrotic phenotype in HSC, we hypothesized that Brucella infection might create a microenvironment that would promote inflammasome activation and a concomitant profibrogenic phenotype in HSC. Our results indicate that Ba infection induces IL-1β secretion (ELISA) by LX-2 cells by a mechanism dependent on a functional T4SS(p
