Acute-phase proteins (APPs) are a class of proteins whose concentrations in blood plasma either increase (positive acute-phase proteins) or decrease (negative acute-phase proteins) in response to inflammation. This response is called the acute …

In the acute phase response, there are changes in the concentration of a number of plasma proteins, called acute phase reactants (APR); these changes are thought to contribute to host defense and adaptive capabilities [4].

2020年9月17日 · Certain mediators, known as acute phase reactants, are increased or decreased in the context of acute inflammation. These markers are commonly measured in clinical practice as indicators of acute illness. An acute phase reaction …

2022年4月4日 · Acute phase reactants (APR) are a group of blood proteins (markers of inflammation) that exhibit significant changes (> 25%) in serum concentration during inflammation such as occurs with infection, rheumatological disorders, trauma or stress.

Acute phase response is the sum of the systemic and metabolic changes oc-curred by release of acute phase proteins in response to inflammatory stimu-lus. The most important ones of these acute phase reactants are erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), fibrinogen and ferritin.

2023年3月13日 · A discussion of the biology of the acute phase response; the general clinical utility and interpretation of measurement of APR, such as CRP; and the clinical utility of indirect measures of the acute phase response, such as the erythrocyte sedimentation rate (ESR), are presented here.

The rapidity and magnitude of the increase in each acute phase protein varies depending on the species. The following table list the acute phase proteins that are major and moderate responders in various animal species.

2014年11月25日 · Examples of acute-phase reactants include (a) coagulation proteins (fibrinogen, prothrombin), (b) transport proteins (haptoglobin, transferrin, ceruloplasmin), (c) complement components (C3, C4), and (d) miscellaneous proteins [fibronectin, serum amyloid A (SAA), C-reactive protein (CRP), ferritin] (Figure 1).

Any of a number of proteins that migrate in the alpha1 and alpha2 regions of a serum protein electrophoresis, which are elevated in acute inflammation. Acute phase reactants traditionally include alpha1-antitrypsin, alpha1 acid glycoprotein, amyloid A and P, anti-thrombin III, CRP, C1-esterase inhibitor, C3 complement, ceruloplasmin, fibrinogen ...

a group of proteins that are produced and/or released in increased concentrations during the acute phase reaction, including fibrinogen; C-reactive protein; complement proteins B, C3, C4; α 2 -acid glycoprotein, serum amyloid A, and proteinase inhibitors.
