acute phase proteins

acute phase proteins

A large number of proteins released into the blood by the liver during infections and which exert a wide range of effects on the inflammatory process, on the function of immune cells and on tissue repair. Acute phase proteins appear in the bloodstream in the early stages of an inflammation or tissue injury as a result of the production of CYTOKINES such as INTERLEUKIN-1 and INTERLEUKIN-6. They include C-REACTIVE PROTEIN, mannose-binding protein, serum amyloid P, fibrinogen, ceruloplasmin, alpha1 antitrypsin, ANGIOTENSIN, haptoglobin and fibronectin.

Unlike cytokines, which have a small size and are rapidly filtered by the kidney, the acute phase proteins have a higher molecular weight (greater than 45kDa), and subsequently a longer permanence in the plasma (SALGADO et al., 2011).
As a result, the relationships among acute phase proteins, anticoagulation proteins, and fibrinolytic system markers show that the coagulation and the fibrinolytic system has an important role in pneumonia pathogenesis and associated inflammation.
Laparoscopic surgery causes less tissue injury than conventional procedures, so the increase in concentrations of biochemical markers of inflammation, such as IL-6 and the acute phase proteins CRP is not as high, while drop in albumin levels are also not so low.

When all patients (both CD and UC) treated with anti-TNF were analyzed, serum levels of prohepcidin at W6 were significantly decreased, compared with levels measured before [T.sub.0] administration (139.42 [+ or -] 18.96 versus 94.14 [+ or -] 9.19 ng/ml, p = 0.0048); consistently, circulating levels of other acute phase proteins, such as ferritin and CRP, were also reduced (68.19 [+ or -] 18.23 versus 37.48[+ or -]13.22 ng/ml, p = 0.0223 and 1.80 [+ or -] 0.42 versus 0.53 [+ or -]0.11 mg/dl, p = 0.0036, resp.).
Specific protocols under study include anaerobic exercise to reverse mitochondrial dysfunction, anti-inflammatories targeting acute phase proteins (C-reactive protein) and cytokines (IL-6 and tumor necrosis factor-alpha), and treatments that augment dopaminergic neurotransmission, he said.
Because captive flamingos often suffer from pododermatitis, feet of all flamingos were scored to determine whether pododermatitis would be reflected in the acute phase proteins. Spearman rank correlation was performed on each of the protein fractions and pododermatitis scores, and only albumin had a significant correlation.

[sup][1] An increasing number of inflammatory markers and acute phase proteins have been tested in CAD, and their plasma levels have been confirmed to be correlated with different clinical characteristics and the prognosis of these patients.
