Abstract: Bortezomib is the first proteasome inhibitor to be used clinically for the treatment of multiple myeloma and has been suggested as a possible treatment for a wide variety of hematologic and solid malignancies. Recent data suggests that potent immunomodulatory effects can also occur with systemic proteasome inhibition. This has been recently shown to occur in a graft-versus host disease model following bone marrow transplantation in mice. The suggested direct immunological effects of bortezomib treatment to include a decrease in anti-apoptotic protein levels, an increase in expression of TNF-family receptors (specifically Apo2L/TRAIL), induction of apoptosis, and inhibition of the transcription factor NF- κB. The NF- κB pathway has been associated with the regulation of numerous immune and inflammatory response mediators. In this review, we will present recent information concerning the potential therapeutic implications of bortezomib for a range of immune disorders. These findings would suggest that bortezomib treatment may be of clinical significance to suppress solid organ transplant rejection, autoreactive T cell responses, pro-inflammatory cytokine production, and consequently disease progression and pathology in autoimmunity.
