Introduction to mannan-binding lectin
Biochemical Society Transactions, 2003Mannan-binding lectin (MBL) was first discovered as a plasma opsonin for baker's yeast and was independently characterized biochemically. It belongs to the small subfamily of collectins: C-type lectins possessing a collagen-like domain. MBL is synthesized by the liver and secreted into the bloodstream.

Mannan-binding lectin in malignancy
Molecular Immunology, 2013Complement may play a dual role in cancer: it may contribute either to the development or to the inhibition of tumour growth. Its components may be candidate biomarkers facilitating the disease detection, its progress or effectiveness of therapy. Additionally, complement deficiencies may increase the risk of infections and contribute to the higher ...

Phytochemistry, 1973
A particulate enzyme system, isolated from growing orchid tubers (Orchis morio), was shown to catalyse the transfer of mannose from guanosine-diphosphate-mannose-14C and its incorporation into alkali-insoluble mannan with the same type of linkage [β(1 → 4)-d-mannopyranosyl] as is contained in the naturally-occurring reserve polysaccharide.

A MANNAN PRODUCED BY BACILLUS POLYMYXA
Canadian Journal of Chemistry, 1959During the fermentation of glucose, sucrose, or lactose by Bacilluspolymyxa, a mixture of polysaccharides is formed, one of which has been isolated by mild procedures and shown to contain mannose as the only sugar together with approximately 13% protein. Acid hydrolysis of the methylated mannan gave 2,3,4,6-tetra-O-methyl-D-mannose, 2,4,6-tri-O-methyl-

A procoagulant chemically sulfated mannan
Carbohydrate Polymers, 2016Disorders of hemostasis can produce innumerous problems. Polysaccharides have been studied both as anticoagulant and as procoagulant agents. A mannan with a main chain of α-(1 → 6)-linked-Manp units, branched at O-2 mainly by side-chains of 2-O-linked-α-Manp units was chemically sulfated, structurally characterized by NMR and GC-MS (methylation ...

The interaction of four lectins from crops of the legume family with Saccharomyces cerevisiae alpha-mannan, and also with two glycoenzymes containing mainly alpha-mannan moieties, has been studied. The interaction was characterized by a quantitative precipitation assay.

Genetic variants of the mannan-binding lectin are associated with immune reactivity to mannans in Crohn’s disease [PDF]
Gastroenterology, 2004 Some patients with Crohn's disease (CD) develop antibodies against mannan, a component of the yeast Saccharomyces cerevisiae cell wall. Mannan-binding lectin (MBL), a component of the innate immune system, can bind to S. cerevisiae . MBL concentration depends on genetic polymorphisms. The aim of this study was to evaluate whether low MBL contributes to

Mannan-Binding lectin in asthma and allergy
Current Allergy and Asthma Reports, 2006Mannan-binding lectin (MBL) is a vital and versatile component of innate immunity. It is present in serum and may bind to a plethora of microbial pathogens and mediate opsonization of these by complement-dependent and/or independent mechanisms. Low-MBL levels in serum, attributed to certain genetic polymorphisms, constitute a major factor predisposing ...

We have studied T- and B-cell responses to antigens of Candida albicans in 18 patients suffering from chronic mucocutaneous candidiasis. We have shown that in vitro production of antibody to one of these antigens, mannan, was absent during the active phase of the disease and that this absence was consequent to the activation of specific CD8(+) and CD8(-
