First, antibodies have a variety of effector mechanisms that focus an array of immunologic agents (complement, various effector cells) on the target to which they bind. Second, antibodies can serve as targeting moieties to specifically deliver diverse killing or inhibitory molecules to a specific site. Third, antibodies can be directed at soluble protein or proteoglycan hormones or cytokines or their receptors to antagonize a particular function such as cell growth, invasion, or migration. Fourth, antibodies can be used as antigens to elicit antitumor responses against immunoglobulin-expressing tumors. Fifth, antibodies can be used to alter the pharmacologic behavior of other substances to either increase or decrease their half-life or alter their distribution (e.g., antibodies to digoxin used to treat digoxin toxicity).
