Clinical manifestations of mannan-binding lectin deficiency

Molecular Immunology, 2006
Mannan-binding lectin (MBL) is a plasma protein of the innate immune system with the ability to initiate antimicrobial and inflammatory actions. MBL deficiency is common. More than 10% of the general population may, depending on definition, be classified as MBL deficient, underlining the redundancy of the immune system.

Mannan-Binding Lectin Enhances Susceptibility to Visceral Leishmaniasis [PDF]

Infection and Immunity, 2001
ABSTRACTLevels of the serum opsonin mannan-binding lectin (MBL) were directly correlated with the probability of developing visceral leishmaniasis. Monocytes infected with MBL-opsonizedLeishmania chagasipromastigotes secreted higher levels of tumor necrosis factor alpha and interleukin-6 than cells infected with nonopsonized parasites.

Health Benefits of Polysaccharides in Red Algae: A Comprehensive Review

Food Frontiers, EarlyView.
Graphical abstract showing the health benefits of red algal polysaccharides. ABSTRACT Humans have long consumed red algae (especially by the Asian community), and their polysaccharide extracts (carrageenan, agar) are extensively used in the food industry as gel thickeners.

Carbohydrate specificity of sea urchin sperm bindin: a cell surface lectin mediating sperm-egg adhesion. [PDF]

, 1982
We have examined the carbohydrate specificity of bindin, a sperm protein responsible for the adhesion of sea urchin sperm to eggs, by investigating the interaction of a number of polysaccharides and glycoconjugates with isolated bindin.

Flocculation in industrial strains of Saccharomyces cerevisiae:role of cell wall polysaccharides and lectin-like receptors [PDF]

, 2017
Yeast flocculation is the reversible aggregation of yeast cells promoted by the interaction between lectin-like protein receptors with mannose side chains on adjacent cell walls.

Herpes simplex encephalitis in adult patients with MASP-2 deficiency.

PLoS Pathogens, 2019
We report here two cases of Herpes simplex virus encephalitis (HSE) in adult patients with very rare, previously uncharacterized, non synonymous heterozygous G634R and R203W substitution in mannan-binding lectin serine protease 2 (MASP2), a gene encoding

Dissection of the anti-Candida albicans mannan immune response using synthetic oligomannosides reveals unique properties of β-1,2 mannotriose protective epitopes

Scientific Reports, 2021
Candida albicans mannan consists of a large repertoire of oligomannosides with different types of mannose linkages and chain lengths, which act as individual epitopes with more or less overlapping antibody specificities. Although anti-C.

Targeting antigens to dendritic cell receptors for vaccine development [PDF]

, 2013
Dendritic cells (DCs) are highly specialized antigen presenting cells of the immune system which play a key role in regulating immune responses. Depending on the method of antigen delivery, DCs stimulate immune responses or induce tolerance.

Activation of the Lectin Pathway Drives Persistent Complement Dysregulation in Long COVID

Immunology, EarlyView.
The complement cascade, a series of blood proteins that assists in the recognition and neutralisation of pathogens, either independently or in conjunction with antibodies, is persistently activated in patients with long COVID. We found that blood plasma samples from patients with long COVID contained elevated concentrations of the mannan‐binding lectin‐
