Abstract
En 中文
Activated T-cell pediatric acute liver failure (TC-PALF) is the most common cause of non-acetaminophen PALF, with poor transplant-free survival. Livers in TC-PALF are infiltrated by effector cytotoxic T lymphocytes with markers of tissue-resident memory function (CD8 Trm) and an interferon gamma (IFNγ) transcriptional signature. The PALF-Immune Response Network (PALF-IRN) and the prospective TReatment for ImmUne-Mediated PathopHysiology (TRIUMPH) clinical trial (NCT04862221) aim to characterize the TC-PALF immune pathology and utility of T-cell directed therapy to improve transplant-free survival.
