Bortezomib, the first-in-class proteasome inhibitor, has become one of the standard treatments in multiple myeloma. The agent is thought to exert its antimyeloma effects through the inhibition of NF-κB. However, evidence suggests that bortezomib also affects additional cell survival pathways, such as the p44/42 mitogen-activated protein kinase pathway, and inhibitory effects on IL-6, TNF-α, and vascular endothelial growth factor have also been demonstrated. These diverse effects have prompted the investigation of bortezomib's activity in various immune and inflammatory processes. This review summarizes the data reported with bortezomib in the prevention of graft-versus-host disease, antibody-mediated graft rejection, and anti-angiogenesis and in the treatment of rheumatoid arthritis, multiple sclerosis, and other inflammatory diseases. The positive results obtained suggest a role for bortezomib in these different indications, and therefore further investigations are warranted.
