Intrabodies as therapeutic agents.

In the past decade, a large number of intracellular antibodies (intrabodies) have been developed for potential use as therapeutic agents. As antibodies can be generated against virtually any target antigen, the applications of intrabodies span a wide range including tumour therapy, infectious diseases, transplantation, and other diseases associated with protein overexpression or mutagenesis. This article summarises the development of intrabodies and their applications as therapeutic agents.
