P-I snake venom metalloproteinase is able to activate the complement system by direct cleavage of central components of the cascade. [PDF]

PLoS Neglected Tropical Diseases, 2013
BACKGROUND: Snake Venom Metalloproteinases (SVMPs) are amongst the key enzymes that contribute to the high toxicity of snake venom. We have recently shown that snake venoms from the Bothrops genus activate the Complement system (C) by promoting direct ...

Ex Vivo Test for Measuring Complement Attack on Endothelial Cells: From Research to Bedside

Frontiers in Immunology, 2022
As part of the innate immune system, the complement system plays a key role in defense against pathogens and in host cell homeostasis. This enzymatic cascade is rapidly triggered in the presence of activating surfaces.

Citrullination in Rheumatoid Arthritis—A Process Promoted by Neutrophil Lysis? [PDF]

Rambam Maimonides Medical Journal, 2016
Anti-citrullinated protein antibodies (ACPAs) are highly specific serologic markers for rheumatoid arthritis (RA) and can pre-date clinical disease onset by up to 10 years, also predicting erosive disease.

The role of the Lys628 (192) residue of the complement protease, C1s, in interacting with peptide and protein substrates

Frontiers in Immunology, 2014
The C1s protease of the classical complement pathway propagates the initial activation of this pathway of the system by cleaving and thereby activating the C4 and C2 complement components.

High Levels of Complement Activating Enzyme MASP-2 Are Associated With the Risk of Future Incident Venous Thromboembolism

Arteriosclerosis, Thrombosis, and Vascular Biology, 2022
Background: Experimental studies have shown that the complement activating enzyme MASP-2 (mannose-binding lectin associated serine protease 2) exhibits a thrombin-like activity and that inhibition of MASP-2 protects against thrombosis.

Gene polymorphism of mannose-binding lectin-associated serine protease (MASP2) in indigenous populations of the Russian Arctic Territories

Инфекция и иммунитет, 2022
Mannose-binding lectin-associated serine proteases (MASP) are among of the key components in the lectin pathway (LP) of the complement activation. MASP-2 is the most studied agent among specific enzymes activating both mannose-binding lectin (MBL) and ...
