Serum complement factor C5a in IgG4-related disease [PDF]

Annals of the Rheumatic Diseases, 2019
We read with great interest the correspondence by Umehara et al 1 which discussed the difficulties in the diagnosis of IgG4-related disease (IgG4-RD). They mention that increased IgG4 concentration is not a specific marker for IgG4-RD. Therefore, the markers for the diagnosis and the disease activity of IgG4-RD are demanded. Approximately a quarter of

Complement component C5a mediates hemorrhage-induced intestinal damage [PDF]

, 2008
Background: Complement has been implicated in the pathogenesis of intestinal damage and inflammation in multiple animal models. Although the exact mechanism is unknown, inhibition of complement prevents hemodynamic alterations in hemorrhage.

Complement Activation in Arterial and Venous Thrombosis is Mediated by Plasmin

EBioMedicine, 2016
Thrombus formation leading to vaso-occlusive events is a major cause of death, and involves complex interactions between coagulation, fibrinolytic and innate immune systems.

Cell-free IgG-aggregates in plasma of patients with chronic lymphocytic leukemia cause chronic activation of the classical complement pathway.

PLoS ONE, 2020
Therapy regimens for Chronic lymphocytic leukemia (CLL) commonly include chemotherapy and immunotherapy, which act through complement-mediated-cytotoxicity (CDC) and other mechanisms.

The interaction between circulating complement proteins and cutaneous microvascular endothelial cells in the development of childhood Henoch-Schönlein Purpura. [PDF]

PLoS ONE, 2015
In addition to IgA, the deposition of complement (C)3 in dermal vessels is commonly found in Henoch-Schönlein purpura (HSP). The aim of this study is to elucidate the role of circulating complement proteins in the pathogenesis of childhood HSP.Plasma ...

Dextran sulfate activates 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

Complement Dysregulation in Obese Versus Nonobese Polycystic Ovary Syndrome Patients

Cells, 2023
Introduction: Upregulation of complement system factors are reported to be increased in polycystic ovary syndrome (PCOS) and may be due to obesity and insulin resistance rather than inherently due to PCOS.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
