Abstract

Evaluation of: Bendle GM, Linnemann C, Hooijkaas AI et al.: Lethal graft-versus-host disease in mouse models of T cell receptor gene therapy. Nat. Med. 16(5), 565-570 (2010). Graft-versus-host disease is commonly associated with allogeneic hematopoietic cell transplantation, as it is the major complication. This article reports that, after immunotherapy with lymphocytes that have been transduced with T-cell receptor (TCR) genes of known specificity, graft-versus-host disease can occur through TCR gene transfer. This autoimmune pathology occurs through the formation of self-reactive TCRs as a result of one chain of the transduced TCR cross-pairing with an endogenous TCR. Certain adjustments in the design of gene therapy vectors may help reduce the risk of such autoimmune phenomena.
