Hepatocyte plasma and mitochondrial membranes

Hepatocyte plasma and mitochondrial membranes are essential cellular structures that define the metabolic and energetic boundaries of liver cells. The plasma membrane contains a diverse array of receptors and transporters, such as the Organic Anion Transporting Polypeptides (OATPs), which facilitate the uptake and excretion of endogenous substances and drugs (Source: PubMed, PMID: 23683520). The mitochondrial membranes are the site of the electron transport chain and are crucial for ATP production and metabolic regulation (Source: UniProt, "Mitochondrion"). While not a single molecular target, these membranes are critical sites for drug action; for instance, Metformin interacts with mitochondrial complex I to influence glucose metabolism (Source: PubChem, "Metformin"). Damage to these membranes is a hallmark of drug-induced liver injury (DILI), often monitored through the release of intracellular enzymes like alanine aminotransferase (Source: LiverTox, NIH). Understanding the integrity and function of these membranes is vital for drug development and safety assessment, as they mediate both therapeutic efficacy and potential toxicity (Source: FDA, "Drug-Induced Liver Injury").

Drugs typically target specific proteins (transporters, enzymes, or receptors) embedded within these membranes rather than the membrane structure itself. Some agents may disrupt membrane integrity, inhibit mitochondrial bioenergetics, or interfere with membrane-bound transport systems.
