Immunoliposomes in vivo.

ABSTRACT

Attachment of antibodies to the surface of liposomes was performed to confer specificity for a certain cell or organ expressing the targeted antigenic determinant. These so-called immunoliposomes are expected to be applied as targeted drug carriers. In this article, the literature concerning in vivo studies of the targeting of immunoliposomes to various sites in the body is reviewed. The anatomical, physiological, and pathological constraints and current progress are described. Moreover, perspectives on the therapeutic feasibility of this drug targeting system are discussed.
