Lipid Signaling Molecules

Meaning

Lipid signaling molecules are a diverse class of bioactive lipids, derived from cell membranes or intracellular synthesis, that function as crucial intercellular and intracellular messengers to regulate a vast array of physiological processes. This category includes eicosanoids, sphingolipids, and various fatty acid derivatives, which mediate inflammation, pain perception, cellular proliferation, and endocrine function. They act as autocrine, paracrine, or endocrine factors, often serving as precursors to or modulators of steroid hormones. Understanding their profile is essential for assessing cellular health and inflammatory status.
