The complement alternative pathway and hemostasis
Immunological Reviews, 2022SummaryThe complement and hemostatic systems are complex systems, and both involve enzymatic cascades, regulators, and cell components—platelets, endothelial cells, and immune cells. The two systems are ancestrally related and are defense mechanisms that limit infection by pathogens and halt bleeding at the site of vascular injury.

The alternative pathway of complement
Springer Seminars in Immunopathology, 1984The alternative pathway of complement activation provides the host with a humoral component of the natural defense mechanisms against infectious agents. The six plasma proteins involved in recognition and activation perform a continuous surveillance function that does not require specific antibody to recognize potential pathogens.

The Complement Alternative Pathway and Preeclampsia
Current Hypertension Reports, 2018Significant and intricate immune adaptations are essential for the establishment and maintenance of normal pregnancy. Preeclampsia is a morbid, potentially life-threatening disease for both mother and neonate that occurs uniquely in pregnancy, at least in part, due to maternal immune maladaptation.

Alternative pathway of complement in multiple myeloma
American Journal of Hematology, 1981AbstractThe alternative pathway of complement was studied in 16 newly diagnosed and 2 previously treated patients with multiple myeloma. Functional activity of this pathway was abnormal in 10 of these 18 patients (55%). These abnormalities correlated with depressed levels of alternative pathway components in 3 of 10 patients, but in the remaining 7, no

[Alternative complement pathway].
La semaine des hopitaux : organe fonde par l'Association d'enseignement medical des hopitaux de Paris, 1984The alternative complement pathway comprises three component proteins C3, B, D and three regulatory proteins P, H and I. These plasma proteins represent the major humoral defense mechanism against infection in a non-immune host. The following topics are reviewed: biochemistry of the alternative pathway proteins; molecular mechanisms of activation and ...

The Alternative Pathway of Complement Activation
1976Publisher Summary This chapter presents the alternative pathway of complement activation. Two pathways for the recruitment of complement and its biological activities exist in plasma and serum. The first is termed as the “classical pathway,” which is triggered by contact of C1 with immune complexes containing antibodies of the immunoglobulin G (IgG ...

Trichomonas vaginalis: alternative pathway activation of complement
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1982Serum from adult human donors lysed Trichomonas vaginalis. The lytic effect was eliminated by heat-inactivation of serum (56 degrees C, 30 min). No serum donor exhibited significantly increased antibody against the parasite as measured by indirect immunofluorescence. Treatment of serum with ethylene glycol-bis (B-aminoethyl ether)-N, N-tetraacetic acid

Gangliosides can activate human alternative complement pathway
International Immunology, 1993The alternative complement pathway (ACP) in vertebrates is known to be important in inflammatory reactions, and to be activated by foreign substances such as bacterial lipopolysaccharide (LPS) and zymosan, although to date no intrinsic activators have been identified except complement receptor type 2.
