Any process that stops, prevents, or reduces the frequency, rate, or extent of cytokine secretion during immune response [goid 2740] [pmid 12458630] [evidence IDA]; The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids [goid 6629] [evidence IEA]; The chemical reactions and pathways resulting in the formation of phosphatidylcholines, any of a class of glycerophospholipids in which the phosphatidyl group is esterified to the hydroxyl group of choline [goid 6656] [pmid 4335615] [evidence IDA]; The directed movement of lipids into, out of, within or between cells. Lipids are compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent [goid 6869] [evidence IEA]; The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand [goid 7186] [pmid 16443932] [evidence IDA]; The chemical reactions and pathways involving steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus [goid 8202] [evidence IEA]; The chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. It is a component of the plasma membrane lipid bilayer and of plasma lipoproteins and can be found in all animal tissues [goid 8203] [evidence IEA]; A series of molecular signals within the cell that are mediated by the Cdc42 protein switching to a GTP-bound active state [goid 32488] [pmid 16443932] [evidence IDA]; The directed movement of cholesterol, cholest-5-en-3-beta-ol, out of a cell or organelle [goid 33344] [pmid 14703508] [evidence IDA]; The directed movement of cholesterol, cholest-5-en-3-beta-ol, out of a cell or organelle [goid 33344] [pmid 16443932] [evidence IDA]; The directed movement of cholesterol, cholest-5-en-3-beta-ol, out of a cell or organelle [goid 33344] [pmid 11162594] [evidence IDA]; The directed movement of a phospholipid out of a cell or organelle [goid 33700] [pmid 14703508] [evidence IDA]; The directed movement of a phospholipid out of a cell or organelle [goid 33700] [pmid 11162594] [evidence IDA]; A lipid modification process in which a sterol ester is formed by the combination of a carboxylic acid (often a fatty acid) and cholesterol. In the blood this process is associated with the conversion of free cholesterol into cholesteryl ester, which is then sequestered into the core of a lipoprotein particle [goid 34435] [pmid 4335615] [evidence IDA]; The chemical reactions and pathways involving any conjugated, water-soluble protein in which the nonprotein moiety consists of a lipid or lipids [goid 42157] [evidence IEA]; Any process involved in the maintenance of an internal equilibrium of cholesterol within an organism or cell [goid 42632] [pmid 15464323] [evidence IMP]; The directed movement of periperal cell cholesterol, cholest-5-en-3-beta-ol, towards the liver for catabolism [goid 43691] [pmid 15464323] [evidence IMP]; Any process that stops, prevents or reduces the frequency, rate or extent of the regulated release of interleukin-1 beta from a cell or group of cells [goid 50713] [pmid 12458630] [evidence IDA]; Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation [goid 50821] [pmid 17655203] [evidence IDA]
