The classic activation pathway of initiation, perpetuation and regression remains as a useful model; however, the emergence of several new pathways and mediators has revealed a deeper complexity than previously appreciated. Although core fibrogenic pathways exist across organs and disease types, there is accumulating evidence for disease- and context-specific mechanisms that may modulate or drive hepatic fibrogenesis. Hence, a "one size fits all" approach to antifibrotic therapy may not be appropriate for all disease settings. The authors present a focused and concise update of the most recent advances in our understanding of hepatic stellate cell activation pathways, while highlighting several challenges that may be constraining progress. This summary provides a foundation to further expand our knowledge of this unique cell type and its contributions to human liver disease.
