Stenosis is a critical problem in the long-term efficacy of tissue-engineered vascular grafts (TEVGs). We previously showed that host monocyte infiltration and activation within the graft drives stenosis and that TGF-? receptor 1 (TGF-?R1) inhibition can prevent it, but the latter effect was attributed primarily to inhibition of mesenchymal cell expansion. In this study, we assessed the effects of TGF-?R1 inhibition on the host monocytes. Biodegradable TEVGs were implanted as inferior vena cava interposition conduits in 2 groups of C57BL/6 mice (n = 25/group): unseeded grafts and unseeded grafts with TGF-?R1 inhibitor systemic treatment for the first 2 wk. The TGF-?R1 inhibitor treatment effectively improved TEVG patency at 6 mo compared to the untreated control group (91.7 vs. 48%, P < 0.001), which is associated with a reduction in classic activation of mononuclear phagocytes. Consistent with these findings, the addition of rTGF-? to LPS/IFN-??stimulated monocytes enhanced secretion of inflammatory cytokines TNF-?, IL-12, and IL-6; this effect was blocked by TGF-?R1 inhibition (P < 0.0001). These findings suggest that the TGF-? signaling pathway contributes to TEVG stenosis by inducing classic activation of host monocytes. Furthermore, blocking monocyte activation by TGF-?R1 inhibition provides a viable strategy for preventing TEVG stenosis while maintaining neotissue formation.?Lee, Y.-U., de Dios Ruiz-Rosado, J., Mahler, N., Best, C.
