In addition to its essential role in immune defense, the complement system
contributes to tissue damage in many clinical conditions. Thus, there is a
pressing need to develop therapeutically effective complement inhibitors to
prevent these adverse effects. This concept, though old, received little s
cientific attention until recently. Data from animal models of diseases tha
t have been produced using complement-deficient, knockout, and transgenic a
nimals, as well as data demonstrating that complement proteins are produced
in many important tissue sites (including the brain) have attracted the in
terest of many basic research scientists and applied scientists from the bi
otechnology field and larger pharmaceutical firms. This resurgence of inter
est has generated a wealth of new information in the field of complement in
hibition, In this article, we comprehensively review up-to-date information
in the field of complement inhibitors. (C) 2000 Elsevier Science B.V. All
