Contribution of the infection-associated complement regulator-acquiring surface protein 4 (ErpC) to complement resistance of Borrelia burgdorferi [PDF]

, 2012
Borrelia burgdorferi evades complement-mediated killing by interacting with complement regulators through distinct complement regulator-acquiring surface proteins (CRASPs).

Human oligodendroglial cells express low levels of C1 inhibitor and membrane cofactor protein mRNAs

Journal of Neuroinflammation, 2004
Background Oligodendrocytes, neurons, astrocytes, microglia, and endothelial cells are capable of synthesizing complement inhibitor proteins. Oligodendrocytes are vulnerable to complement attack, which is particularly observed in multiple sclerosis. This

The membrane attack complex as an indicator of complement hyperactivation in type 2 diabetes mellitus

Сахарный диабет, 2011
Aim. Comparative analysis of the levels of the membrane attack complex (MAC) - an end product of complement activation, and of hemolytic activitiesof C1 and C3 complement components in sera of patients with diabetes mellitus 2 (DM2) and healthy subjects.

COMPLEMENT-MEDIATED ADIPOCYTE LYSIS BY NEPHRITIC FACTOR SERA [PDF]

, 1993
Recent data indicate a previously unsuspected link between the complement system and adipocyte biology. Murine adipocytes produce key components of the alternative pathway of complement and are able to activate this pathway.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

A Novel C1-Esterase Inhibitor Oxygenator Coating Prevents FXII Activation in Human Blood

Biomolecules, 2020
The limited hemocompatibility of currently used oxygenator membranes prevents long-term use of artificial lungs in patients with lung failure. To improve hemocompatibility, we developed a novel covalent C1-esterase inhibitor (C1-INH) coating.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Angioedema hereditario en Medellín, Colombia: evaluación clínica y de la calidad de vida

Biomédica: revista del Instituto Nacional de Salud, 2015
Introducción. El angioedema hereditario es una inmunodeficiencia primaria de carácter autosómico dominante, debida a un déficit en la proteína inhibidora del factor C1 y caracterizada por episodios recurrentes de edema subcutáneo y de las mucosas.

The role of C1 inhibitor and complement as acute phase reactants: are we missing the diagnosis of hereditary angioedema?

Allergy, Asthma & Clinical Immunology, 2021
Background C1 inhibitor (C1-INH) and complement 4 (C4) have historically been referred to as positive acute phase reactants, however this has never been evaluated in hereditary angioedema (HAE) patients.

Characterization and functional analysis of mouse Ficolin B [PDF]

, 2012
The innate immune system contributes day by day to the elimination of invading pathogens. The lectin pathway of the complement system is initiated when mannose-binding-lectin (MBL) or ficolins interact with MASP-2.
