Complement activation in psoriasis
Clinical and Experimental Dermatology, 1990Plasma from 16 patients with psoriasis and 12 healthy control subjects were measured for iC3b, C4d, and Bb fragments generated by complement activation. Plasma concentrations for iC3b, C4d, and Bb fragments were found to be significantly increased in the patients with psoriasis.

Complement activation and atherosclerosis
Molecular Immunology, 1999Atherosclerosis is an inflammatory disease mediated through the action of monocyte/macrophages, complement and T-lymphocytes. C5a and monocyte chemotactic factor released during complement activation in the arterial wall may participate in the initial monocyte recruitment. Assembly of C5b-9 on cells of the arterial wall may also induce cell lysis.

Activation of complement by Naegleria
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1980Neither Naegleria nor its culture supernatant was found to be directly chemotactic for human neutrophils. Interaction of Naegleria with human serum, however, resulted in the generation of a strong chemotactic stimulus. The reduction of serum activity by heat-inactivation indicated a dependence on serum complement for the interaction.

Complement activation in pneumonia
Medical Microbiology and Immunology, 1979Complement analyses performed on serially collected plasma samples from 10 patients during acute infectious pneumonia or bronchopneumonia showed normal or increased values for hemolytic activity and Clq, C4, C3, and factor B levels. However, the levels of C3 breakdown products (C3d) were significantly (greater than 2 SD) increased in six patients ...

COMPLEMENT ACTIVATION IN MIGRAINE
The Lancet, 1977Forty patients attending the Prince Henry Hospital migraine clinic have been investigated for evidence of complement activation related to migraine. These patients had a history of clinically similar migraine attacks. Levels of serum complement components were determined in nine patients, both in and out of migraine.

Biological Activities of Complement
Biochemical Society Transactions, 1978Complement is a system of serum proteins whose main function is to defend the body against infection. Although it has a reputation as a dauntingly complex system, this results chiefly from confusion in the nomenclature, which has varied considerably with time as more components were discovered, for example as ‘component C3’ became subdivided into ...

Activation of complement by trypanosomes
Experientia, 1977Factors exhibiting anti-complementary activity released from trypanosomes after incubation at 20 degrees C were described. The active material was shown to consume the first component of bovine complement. While the anti-complementary factor(s) from T. lewisi could activate bovine, human and guinea pig complement, the factor(s) from T.

Assays for Complement Activation
Clinics in Laboratory Medicine, 1986Complement is a major biologic mediation system that functions in host defense against microorganisms and other pathogens and also aids in the elimination of damaged and abnormal cells. This is accomplished by its ability to mediate the destruction of pathogens and altered cells directly through cytolytic and cytotoxic properties, as well as indirectly

Complement Activation and Pregnancy Failure
Clinical Reviews in Allergy & Immunology, 2009Pregnancy represents a physiologic condition where maternal immune system tolerates the semi-allogenic fetus. The fetal tissues are directly exposed to the maternal blood with potential attacks from maternal immune system, including the activation of complement cascade. Small amounts, of both early and late components, of complement are physiologically

Ficolins in complement activation
Molecular Immunology, 2013Ficolins are a group of multimeric lectins made up of single subunits each of which is composed of a collagen-like domain and a fibrinogen-like domain. Most of the ficolins identified to date bind to acetylated compounds such as N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (GalNAc).
