The level of procalcitonin rises in a response to a pro-inflammatory stimulus, especially of bacterial origin. It is therefore often classed as an acute phase reactant . [ 4 ] The induction period for procalcitonin ranges from 4–12 hours with a half-life spanning anywhere from 22–35 hours. [ 5 ]
suPAR is a biomarker reflecting the level of activity of the immune system in response to an inflammatory stimulus. suPAR levels positively correlate with pro-inflammatory biomarkers, including tumor necrosis factor-α (TNFα) and C-reactive protein (CRP) and other parameters, including leukocyte counts. suPAR is also associated with organ damage in various diseases.[2-5] Elevated levels of ...
Positive acute-phase proteins serve (as part of the innate immune system) different physiological functions within the immune system.Some act to destroy or inhibit growth of microbes, e.g., C-reactive protein, mannose-binding protein, [3] complement factors, ferritin, ceruloplasmin, serum amyloid A and haptoglobin.

An inflammatory cytokine or proinflammatory cytokine is a type of signaling molecule (a cytokine) that is secreted from immune cells like helper T cells (T h) and macrophages, and certain other cell types that promote inflammation.
Experimental tests that could be useful in the future include tests to measure semen and prostate fluid cytokine levels. Various studies have shown increases in markers for inflammation such as elevated levels of cytokines, [40] [41] myeloperoxidase, [42] and chemokines. [43]
Nicotinamide (a form of vitamin B 3) is a potent inhibitor of proinflammatory cytokines. [8] [9] Low blood plasma levels of trigonelline (one of the metabolites of vitamin B3) have been suggested for the prognosis of SARS-CoV-2 death (which is thought to be due to the inflammatory phase and cytokine storm).
Type 2 inflammation is a pattern of immune response. Its physiological function is to defend the body against helminths , but a dysregulation of the type 2 inflammatory response has been implicated in the pathophysiology of several diseases.
