Physiological Roles of Prostaglandins and Other Eicosanoids in Invertebrates

Prostaglandins and other biologically active derivatives of polyunsaturated fatty acids have been detected in a large number of invertebrate species. A brief summary of the mammalian background of arachidonic acid metabolism is provided, and the physiological significance of these compounds in invertebrates is reviewed. Topics include regulation of ion flux, temperature regulation, reproductive biology, cell aggregation, and host-parasite interactions. Finally, perspectives on current and possible future research are offered.
