Amniotic fluid embolism pathophysiology suggests the new diagnostic armamentarium: β-tryptase and complement fractions C3-C4 are the indispensable working tools [PDF]
, 2015 Amniotic fluid embolism (AFE) is an uncommon obstetric condition involving pregnant women during labor or in the initial stages after delivery. Its incidence is estimated to be around 5.5 cases per 100,000 deliveries.

Decay accelerating factor (CD55) protects neuronal cells from chemical hypoxia-induced injury
Journal of Neuroinflammation, 2010 Background Activated complement system is known to mediate neuroinflammation and neurodegeneration following exposure to hypoxic-ischemic insults. Therefore, inhibition of the complement activation cascade may represent a potential therapeutic strategy ...

Dextran sulfate activates the contact system and mediates arterial hypotension via B2 kinin receptors [PDF]
, 1994 To define some of the mechanisms underlying dextran sulfate (DXS)-induced hypotension, we investigated the effects of either the plasma kallikrein inhibitor des-Pro2-[Arg15] aprotinin (BAY x 4620) or the specific bradykinin B2-receptor antagonist Hoe-140

Distinct roles for C3a and C5a in complement-induced tubulointerstitial injury [PDF]
Kidney International, 2011 To prevent injury to host tissues, complement activation is regulated by a number of plasma and membrane-associated proteins, most of which limit C3 and C5 activation. An influx of circulating C3 from a syngeneic host into donor kidneys deficient in Crry (a membrane protein that reduces C3 convertase activity) causes spontaneous complement activation ...

Tissue plasminogen activator mediates deleterious complement cascade activation in stroke. [PDF]
PLoS ONE, 2017 The use of intravenous tissue plasminogen activator (tPA) in the treatment of ischemic stroke is limited by its propensity to exacerbate brain edema and hemorrhage. The mechanisms underlying these deleterious effects of tPA remain incompletely understood.

Induction of Complement C3a Receptor Responses by Kallikrein-Related Peptidase 14 [PDF]
The Journal of Immunology, 2013 Abstract Activation of the complement system is primarily initiated by pathogen- and damage-associated molecular patterns on cellular surfaces. However, there is increasing evidence for direct activation of individual complement components by extrinsic proteinases as part of an intricate crosstalk between physiological effector systems ...

Modulation of human lymphocyte function by C3a and C3a(70-77). [PDF]
, 1982 Human C3a and the synthetic octapeptide C3a (70-77), which retains the activities of an anaphylatoxin, inhibit in a concentration-dependent manner the generation of leukocyte inhibitory factor (LIF) activity by human mononuclear leukocytes and T ...

The “C3aR Antagonist” SB290157 is a Partial C5aR2 Agonist
Frontiers in Pharmacology, 2021 Innate immune complement activation generates the C3 and C5 protein cleavage products C3a and C5a, defined classically as anaphylatoxins. C3a activates C3aR, while C5a activates two receptors (C5aR1 and C5aR2) to exert their immunomodulatory activities ...
