In vivo clearance by the mononuclear phagocyte system in humans: an overview of methods and their interpretation

Abstract

SUMMARY The mononuclear phagocyte system (MPS) is responsible for the elimination of foreign material, effete autologous material and immune complexes. To study the relationship between MPS function and human disease, several test substances have been developed, and used to determine the clearance capacity of the MPS in human subjects in vivo. These test substances and the multitude of factors that influence the elimination of these substances (and complicate the interpretation of the test results) are discussed. Use of these probes bas provided important new insights, that may lead to the development of treatment modalities by which MPS function is modified in order to influence disease processes more effectively.
