Abstract

The intracellular, gram-negative pathogen Brucella abortus establishes chronic infections in host macrophages while downregulating cytokines such as tumor necrosis factor alpha (TNF-alpha). When producing TNF-alpha, Brucella abortus rough lipopolysaccharide (LPS) activates the same mitogen-activated protein kinase signaling pathways (ERK and JNK) as Escherichia coli LPS, but Brucella LPS is a much less potent agonist.
