Hepatic cell junctions: Pulling a double‐duty

Abstract

AbstractCell junctions, including anchoring, occluding and communicating junctions, play an indispensable role in the structural and functional organization of multicellular tissues, including in liver. Specifically, hepatic cell junctions mediate intercellular adhesion and communication between liver cells. The establishment of the hepatic cell junction network is a prerequisite for normal liver functioning. Hepatic cell junctions indeed support liver‐specific features and control essential aspects of the hepatic life cycle. This review paper summarizes the role of cell junctions and their components in relation to liver physiology, thereby also discussing their involvement in hepatic dysfunctionality, including liver disease and toxicity.
