Progressive IgA Nephropathy Is Associated With Low Circulating Mannan-Binding Lectin–Associated Serine Protease-3 (MASP-3) and Increased Glomerular Factor H–Related Protein-5 (FHR5) Deposition

Kidney International Reports, 2018
IgA nephropathy (IgAN) is characterized by glomerular deposition of galactose-deficient IgA1 and complement proteins and leads to renal impairment. Complement deposition through the alternative and lectin activation pathways is associated with renal ...

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.

Backbone dynamics of complement control protein (CCP) modules reveals mobility in binding surfaces [PDF]

, 2004
The regulators of complement activation (RCA) are critical to health and disease because their role is to ensure that a complement-mediated immune response to infection is proportionate and targeted.

Borrelia recurrentis employs a novel multifunctional surface protein with anti-complement, anti-opsonic and invasive potential to escape innate immunity [PDF]

, 2009
Borrelia recurrentis, the etiologic agent of louse-borne relapsing fever in humans, has evolved strategies, including antigenic variation, to evade immune defence, thereby causing severe diseases with high mortality rates.

TIGIT-positive circulating follicular helper T cells display robust B-cell help functions: potential role in sickle cell alloimmunization

Haematologica, 2015
T follicular helper cells are the main CD4+ T cells specialized in supporting B-cell responses, but their role in driving transfusion-associated alloimmunization is not fully characterized.

Carbohydrate recognition and complement activation by rat ficolin-B [PDF]

, 2010
Ficolins are innate immune components that bind to PAMPs and structures on apoptotic cells. Humans produce two serum forms (L-and H-ficolin) and a leukocyte-associated form (M-ficolin), whereas rodents and most other mammals produce ficolins-A and -B ...

Properdin deficiency or anti-properdin treatment ameliorates disease in the C3 gain-of-function mouse model of atypical haemolytic uraemic syndrome

Frontiers in Immunology
IntroductionWe have previously shown that the C3D1115N mouse, engineered around a single point mutation in C3 associated with atypical haemolytic uraemic syndrome (aHUS) in man, fully recapitulates the clinical disease. In this study, we investigated the

A hierarchical role for classical pathway complement proteins in the clearance of apoptotic cells in vivo [PDF]

, 2000
The strongest susceptibility genes for the development of systemic lupus erythematosus (SLE) in humans are null mutants of classical pathway complement proteins. There is a hierarchy of disease susceptibility and severity according to the position of the
