Paths reunited: initiation of the classical and lectin pathways of complement activation [PDF]

, 2010
Understanding the structural organisation and mode of action of the initiating complex of the classical pathway of complement activation (C1) has been a central goal in complement biology since its isolation almost 50 years ago.

Association of Chlamydia pneumoniae with coronary artery disease and its progression is dependent on the modifying effect of mannose-binding lectin [PDF]

, 2002
Background— The possible association between coronary artery disease (CAD) and Chlamydia pneumoniae (C pneumoniae) infection is controversial. On the basis of the recent suggestion that mannose-binding lectin (MBL) variant alleles are related to an ...

Mannan-binding lectin inhibits Candida albicans-induced cellular responses in PMA-activated THP-1 cells through Toll-like receptor 2 and Toll-like receptor 4. [PDF]

PLoS ONE, 2013
BACKGROUND:Candida albicans (C. albicans), the most common human fungal pathogen, can cause fatal systemic infections under certain circumstances. Mannan-binding lectin (MBL),a member of the collectin family in the C-type lectin superfamily, is an ...

Serum MASP-1 in complex with MBL activates endothelial cells. [PDF]

, 2014
The complement system plays an important role in the induction of inflammation. In this study we demonstrate that the initiation complexes of the lectin pathway, consisting of mannose-binding lectin (MBL) and associated serine proteases (MASPs) elicit ...

The salivary scavenger and agglutinin (SALSA) binds MBL and regulates the lectin pathway of complement in solution and on surfaces

Frontiers in Immunology, 2012
The scavenger receptor cysteine-rich (SRCR) protein SALSA, also known as gp340, salivary agglutinin (SAG) and deleted in malignant brain tumor 1 (DMBT1), is a 340 kDa glycoprotein expressed on mucosal surfaces and secreted into several body fluids. SALSA

Mannan-binding lectin ameliorates renal fibrosis by suppressing macrophage-to-myofibroblast transition

Heliyon, 2023
Mannan-binding lectin (MBL) is a pattern-recognition molecule that plays a crucial role in innate immunity. MBL deficiency correlates with an increased risk of chronic kidney disease (CKD). However, the molecular mechanisms are not fully defined.

Mannose-binding lectin in severe acute respiratory syndrome coronavirus infection [PDF]

, 2005
Little is known about the innate immune response to severe acute respiratory syndrome (SARS) coronavirus (CoV) infection. Mannose-binding lectin (MBL), a key molecule in innate immunity, functions as an ante-antibody before the specific antibody response.

A likely association between low mannan-binding lectin level and brain fog onset in long COVID patients

Frontiers in Immunology, 2023
Brain fog can be described as a constellation of new-onset neuropsychiatric sequelae in the post-acute phase of COVID-19 (long COVID). The symptoms include inattention, short-term memory loss, and reduced mental acuity, which may undermine cognition ...

O-GalNAc Glycosylation Activates MBL-Mediated Complement and Coagulation Cascades to Drive Organotropic Metastasis. [PDF]

Adv Sci (Weinh)
Upregulated glycosyltransferase GALNT9 in neuroendocrine (NE) carcinomas increases O‐GalNAc glycosylation on cell membrane proteins, particularly Annexin‐A2 (ANXA2). Elevated O‐GalNAc glycan induces the binding of NE cancer cells to mannose binding lectin 2 (MBL2), activating the MBL‐MBL associated serine protease (MBL‐MASP) complement pathway in the ...

High glucose disrupts oligosaccharide recognition function via competitive inhibition : a potential mechanism for immune dysregulation in diabetes mellitus [PDF]

, 2011
Diabetic complications include infection and cardiovascular disease. Within the immune system, host-pathogen and regulatory host-host interactions operate through binding of oligosaccharides by C-type lectin.
