Mannose-binding lectin 2 gene and risk of adult glioma. [PDF]

open access: yesPLoS ONE, 2013
The immune system is likely to play a key role in the etiology of gliomas. Genetic polymorphisms in the mannose-binding lectin gene, a key activator in the lectin complement pathway, have been associated with risk of several cancers.To examine the role ...

Fasciola hepatica is refractory to complement killing by preventing attachment of mannose binding lectin (MBL) and inhibiting MBL-associated serine proteases (MASPs) with serpins.

open access: yesPLoS Pathogens, 2022
The complement system is a first-line innate host immune defence against invading pathogens. It is activated via three pathways, termed Classical, Lectin and Alternative, which are mediated by antibodies, carbohydrate arrays or microbial liposaccharides,

Collectin-11/MASP Complex Formation Triggers Activation of the Lectin Complement Pathway - The Fifth Lectin Pathway Initiation Complex [PDF]

open access: yesJournal of Innate Immunity, 2012
Collectins and ficolins are important in the clearance of endogenous and exogenous danger materials. A new human collectin-11 was recently identified in low concentration in serum in complex with mannose-binding lectin (MBL)/ficolin-associated serine proteases. Collectin-11 binds to carbohydrate residues present on various microorganisms.

Complementary Roles of the Classical and Lectin Complement Pathways in the Defense against Aspergillus fumigatus

open access: yesFrontiers in Immunology, 2016
Aspergillus fumigatus infections are associated with a high mortality rate for immunocompromised patients. The complement system is considered to be important in protection against this fungus, yet the course of activation is unclear.

Classical and lectin complement pathways and markers of inflammation for investigation of susceptibility to infections among healthy older adults

open access: yesImmunity & Ageing, 2020
Background There is increasing recognition of the significance of chronic, low-level inflammation in older adults, or “inflammaging.” Innate immune responses and host-bacterial interactions are recognized as key factors in inflammaging.

Scabies mite inactive serine proteases are potent inhibitors of the human complement lectin pathway. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2014
Scabies is an infectious skin disease caused by the mite Sarcoptes scabiei and has been classified as one of the six most prevalent epidermal parasitic skin diseases infecting populations living in poverty by the World Health Organisation.

The Complement System of Agnathans

open access: yesFrontiers in Immunology, 2018
Agnathans (lamprey and hagfish) are a group of primitive jawless fish. Jawed vertebrates possess adaptive immunity including immunoglobulins, while agnathans lack immunoglobulins but have alternative adaptive immunity in which variable lymphocyte ...

Enhancement of lectin pathway haemolysis by immunoglobulins

open access: yesClinical and Experimental Immunology, 1999
SUMMARYWe recently reported that indicator sheep erythrocytes (E) coated with mannan and sensitized with mannan-binding lectin (MBL) (E-M-MBL) are lysed by human serum in the absence of calcium via the lectin pathway of complement activation by a process which requires alternative pathway amplification and is associated with increased binding of and ...

Association Study of Mannose-Binding Lectin Levels and Genetic Variants in Lectin Pathway Proteins with Susceptibility to Age-Related Macular Degeneration: A Case-Control Study. [PDF]

open access: yesPLoS ONE, 2015
In age-related macular degeneration (AMD) the complement system is thought to be activated by chronic oxidative damage with genetic variants identified in the alternative pathway as susceptibility factors.

Isolation and characterization of novel primary cells from the human distal outflow pathway

open access: yesScientific Reports, 2021
Ocular hypertension occurs due to increased resistance to aqueous humor removal through the conventional outflow pathway. Unlike the proximal region of the conventional outflow pathway, the distal region has not been well studied, mostly due to lack of ...
