Lipid signaling refers to the process by which lipids, a type of fat molecule, act as signaling molecules in the body. These lipids can influence various cellular functions, including inflammation, cell growth, and metabolism. They play a crucial role in communication between cells, helping to regulate physiological responses. One important group of lipid signaling molecules is eicosanoids, which are derived from fatty acids. Eicosanoids include prostaglandins and leukotrienes, which are involved in immune responses and the regulation of blood pressure. Understanding lipid signaling is essential for developing treatments for various diseases, including cancer and cardiovascular disorders.
