title: Release of arachidonic acid: a new function of the late complement components.
abstract: Incubation of Ehrlich-ascites cells with sublytic complement doses results in degradation of membrane phospholipids and release of arachidonic acid. Phospholipase A2 blockers inhibit arachidonic acid release indicating a phospholipase dependent cleavage of the phospholipids. Phospholipase A2 is apparently activated during complement-membrane interaction, representing a new reactivity of the late complement components.
