Acta Obstetricia et Gynecologica Scandinavica, Volume 104, Issue 5, Page 829-838, May 2025.Preeclampsia fetuses show an altered profile of endothelial damage and complement biomarkers, like increased adhesion molecules, prothrombotic state, oxidative stress, and reduced complement membrane attack complex deposition on endothelial cells. Abstract Introduction Our objective was to evaluate the endothelial function profile and complement system

Advanced Science, Volume 12, Issue 10, March 13, 2025.Immune thrombocytopenia (ITP) is an autoimmune disorder marked by reduced platelet levels and heightened susceptibility to bleeding resulting from augmented autologous platelet destruction and diminished thrombopoiesis. It is found that the lectin pathway of the complement system, resistin, MIF, and AA metabolism may serve as promising targets for ...

Two New Kindreds with Complete Factor D Deficiency
European Journal of Immunology, Volume 55, Issue 3, March 2025.The complement system plays a crucial role in immune defense, and factor D deficiency is a rare immunodeficiency associated with life‐threatening bacterial infections. We report two new cases of complete factor D deficiency, including the first described in a Down syndrome patient, highlighting the need to investigate complement deficiencies in ...

Enhancement of platelet response to immune complexes and IgG aggregates by lipid A-rich bacterial lipopolysaccharides. [PDF]
, 1978 The effect of the common lipid moiety of bacterial LPS on secretion from washed human platelets has been studied. The lipid A-rich LPS of S. minnesota R595 and a lipid A preparation both potentiated platelet serotonin secretion in response to IgG ...

A molecular concept of the properdin pathway. [PDF]
Proceedings of the National Academy of Sciences, 1976 The sequential events of the properdin system were analyzed. Properdin-depleted serum allows the formation of a Factor B- and D-dependent C3 convertase. This enzyme, called the properdin-receptor-forming enzyme, was shown to utilize a novel serum component, the initiating factor.

Methods for detecting, building, and improving tryptophan mannosylation in glycoprotein structures
Protein Science, Volume 34, Issue 2, February 2025.Abstract Tryptophan mannosylation, the covalent addition of an α‐ᴅ‐mannose sugar to a tryptophan side chain, is a post‐translational modification (PTM) that can affect protein stability, folding, and interactions. Compared to other forms of protein glycosylation, it is relatively uncommon but is affected by conformational anomalies and modeling errors ...
