Acute phase proteins (APPs) are a large group of proteins synthesized by the liver cells and released into the bloodstream in response to a variety of stressors as part of the acute phase of the inflammatory reaction. Proteins with a transient increase in synthesis and plasma concentration are called positive, whereas proteins whose synthesis decreases are referred to as negative APPs. The synthesis of the APP is thought to be mainly regulated by inflammatory cytokines, such as interleukin-6, interleukin-1 and tumor necrosis factor.
APPs functioning as protease inhibitors, enzymes, transport proteins, coagulation proteins, and modulators of the host’s immune response, and play a role in the restoration of homeostasis after injury or infection. APPs act in a time, concentration and molecular conformation- dependent manner on a variety of cells involved in early and late stages of inflammation. APPs can directly contribute to the enhancement and/or the suppression of inflammation at different points in its evolution. The administration of specific APPs has been shown to switch the pro-inflammatory to the anti-inflammatory pathways necessary for the resolution of inflammation in vitro and in vivo. Nevertheless, the biological function of most APPs has not been totally elucidated. It is also not clear what functional advantages may arise from the rapid changes in the blood profile of APPs as a group.
Thus, the magnitude and rapidity of the changes in the specific profile of APPs, together with their short half-life, suggest a particularly important role for these proteins in the establishment of host defense. The functional activities of specific APPs and their quantification during the course of acute and chronic inflammation are discussed in this book.
