Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis
Hepatology, EarlyView., 2022 Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.
