Core Tip
Core Tip: Torque teno virus (TTV) is a ubiquitous, highly prevalent, and mostly indolent DNA virus in the general population. Historically, it has been associated with different liver diseases, but the virus's pathogenicity is controversial. TTV viral load is modulated by immune, viral, and inflammatory status. TTV viral load positively correlates with the intensity of immunosuppression, making it an attractive surrogate biomarker for immune monitoring in different patient cohorts, including liver transplant recipients. However, the TTV role as a single or a panel biomarker needs to be evaluated in further trials.
