Pasteurella multocida Toxin Manipulates T Cell Differentiation
Pasteurella multocida causes various diseases in a broad range of wild and domestic animals. Toxigenic strains of the serotypes A and D produce an AB protein toxin named Pasteurella multocida toxin (PMT). PMT constitutively activates the heterotrimeric G protein subunits Gαq, Gα13, and Gαi through deamidation of a glutamine residue, which results in cytoskeletal rearrangements as well as increa...
متن کاملPasteurella multocida toxin-stimulated osteoclast differentiation is B cell dependent.
Pasteurella multocida is a Gram-negative bacillus that infects a number of wild and domestic animals, causing respiratory diseases. Toxigenic Pasteurella multocida strains produce a protein toxin (PMT) that leads to atrophic rhinitis in swine due to enhanced osteoclastogenesis and the inhibition of osteoblast function. We show that PMT-induced osteoclastogenesis is promoted by an as-yet-unchara...
متن کاملAssociation of Pasteurella multocida toxin with vimentin.
To help understand the molecular mechanisms of Pasteurella multocida toxin (PMT) action, we searched for a cellular protein interacting with PMT. The ligand overlay assay revealed a 60-kDa cellular protein that binds to a region from the 840th to 985th amino acids of the toxin. This protein was identified as vimentin by peptide mass fingerprinting. The N-terminal head domain of vimentin was fur...
متن کاملPasteurella multocida Toxin Triggers RANKL-Independent Osteoclastogenesis
Bone remodeling is a continuous process to retain the structural integrity and function of the skeleton. A tight coupling is maintained between osteoclast-mediated resorption of old or damaged bones and osteoblast-mediated formation of new bones for bone homeostasis. While osteoblasts differentiate from mesenchymal stem cells, osteoclasts are hematopoietic in origin and derived from myeloid pre...
متن کاملPasteurella multocida toxin activation of heterotrimeric G proteins by deamidation.
Pasteurella multocida toxin is a major virulence factor of Pasteurella multocida, which causes pasteurellosis in men and animals and atrophic rhinitis in rabbits and pigs. The approximately 145 kDa protein toxin stimulates various signal transduction pathways by activating heterotrimeric G proteins of the Galpha(q), Galpha(i), and Galpha(12/13) families by using an as yet unknown mechanism. Her...
