NRG1 and Behcet disease: As the BD event progresses, our results indicated that BD triggers a mechanistic process in both liver types to maintain elevated NRG1 levels, and this effect is observed in liver grafts from BD donors after cold ischemia (before the implantation of liver grafts in the recipient: the Prior to BD+LT group), as well as at 4 h after transplantation (after implantation of liver grafts: the BD+LT group).
