In addition to autotaxin, lysophosphatidic acid (LPA) levels normalize during interferon (IFN)–free direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) infection. A and B, Levels of autotaxin (A) and LPA subtypes 16:0, 18:1, 18:2, and 20:4 (B), with the lower level of detection of 0.05 shown in dotted line. C, Percentage of total LPA that is LPA 16:0, 18:1, 18:2, or 20:4 in 5 UD participants and 10 HCV-infected participants at baseline, week 8, and week 24 of IFN-free DAA therapy for HCV. *P < .05, **P < .01, and ***P < .001. Abbreviation: UD, uninfected donor.
