Eicosanoids cell proliferation role

Lipids can be involved in immunity in a number of ways, principally through their roles in membrane integrity and in providing precursors for eicosanoid formation. Thus, the proliferation of lymphocytes involves rapid synthesis of new membranes the interaction of antigens with receptors on the lymphocyte surface is influenced by the physico-chemical properties of the membrane (sections 6.5.4 and 8.1) and the eicosanoids play a key role in inflammatory reactions. Dietary lipids may modulate immune reactions, therefore, either by modifying the composition of cell membranes and membrane surface components or by influencing the nature of the precursor pool for eicosanoids.
