Cellular membrane and lipid metabolic pathway

The term "cellular membranes and lipid metabolic pathways" does not refer to a specific molecular target but to a broad class of cellular structures (membranes) and the complex networks regulating lipid metabolism. Cellular membranes comprise lipid bilayers, including phospholipids, cholesterol, and sphingolipids, which are essential for cell compartmentalization, signaling, and homeostasis. Lipid metabolic pathways include enzymes and regulatory proteins that control the synthesis, degradation, and remodeling of these lipid molecules. Alterations in membrane lipid composition and lipid metabolism play critical roles in disease processes including cancer, neurodegenerative disorders, and metabolic diseases, making various membrane lipids, lipid-modifying enzymes, and regulatory proteins promising therapeutic targets[1][2][3][4]. Therapeutic strategies may involve modulating lipid profiles, targeting key enzymes or nuclear receptors, or altering membrane microdomain organization (e.g., lipid rafts) to affect signaling and cell survival. However, "cellular membranes and lipid metabolic pathways" is a systems-level concept, not a discrete druggable target or single molecular entity, and should not be treated as a canonical therapeutic target itself.
