ADAM9 silencing inhibits breast tumor cells transmigration through blood and lymphatic endothelial cells.

ADAMs are transmembrane multifunctional proteins that contain disintegrin and metalloprotease domains. ADAMs act in a diverse set of biological processes, including fertilization, inflammatory responses, myogenesis, cell migration, cell proliferation and ectodomain cleavage of membrane proteins. These proteins also have additional functions in pathological processes as cancer and metastasis development.

The infection of microvascular endothelial cells with ExoU-producing Pseudomonas aeruginosa triggers the release of von Willebrand factor and platelet adhesion.

An increased plasma concentration of von Willebrand factor (vWF) is detected in individuals with many infectious diseases and is accepted as a marker of endothelium activation and prothrombotic condition. To determine whether ExoU, a Pseudomonas aeruginosa cytotoxin with proinflammatory activity, enhances the release of vWF, microvascular endothelial cells were infected with the ExoU-producing PA103 P. aeruginosa strain or an exoU-deficient mutant.

The in vitro interaction of Sporothrix schenckii with human endothelial cells is modulated by cytokines and involves endothelial surface molecules.

Sporothrix schenckii is the etiological agent of sporotrichosis, a subcutaneous mycosis that can evolve to systemic complications in immunocompromised patients. Interactions with endothelium are thought to be essential for systemic infections. In the present work, we studied the interaction between S.
