title: Role of complement components on cells and in cell interactions.
abstract: The complement system, though complex, is relatively easy to study both in terms of its reaction pathways, its distribution and its genetics. There is reason to believe that the complement system is involved in cell surface events and interactions at a variety of levels and we may hope that the knowledge of the system in the blood plasma will provide relatively easy insights into the more difficult areas with cells.
