OBJECTIVE Mannan-binding lectin (MBL) is a central component of the innate immune response. Genetic variations in the MBL gene that reduce circulating levels and alter functional properties of the MBL are associated with susceptibility for many infectious diseases. Crimean-Congo hemorrhagic fever

Ischemia/reperfusion (I/R) is an important cause of acute renal failure. Recent studies have shown that the complement system mediated by the mannan-binding protein (MBP), which is a C-type serum lectin recognizing mannose, fucose and N-acetylglucosamine residues, plays a critical role in the

Disorders 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,

Mannan-binding lectin (MBL) triggers complement activation upon binding to microbial surfaces. MBL deficiency has been associated with increased susceptibility to severe bacterial infections. We hypothesized that MBL deficiency may predispose children to Shiga toxin-producing Escherichia coli (STEC)

Background: A subarachnoid hemorrhage (SAH) is a debilitating stroke. Activation of the lectin pathway (LP) of the complement system in SAH patients could worsen the prognosis; however, conflicting results have been reported. This

We encountered a case of an 83-year-old patient with candida endocarditis. He had been diagnosed as having aortic regurgitation with moderately calcified aortic valve 5 years previously, and had received medication. He was admitted to our hospital because of pancreatic cancer. He had high fever from

There remains today a critical need for new antiviral agents, particularly in view of the alarming increase in drug resistance and associated issues. The marine environment has been a prolific contributor towards the identification of novel therapeutic agents in the recent few decades. Added to

Bleeding disorders and thrombotic complications constitute a major cause of death and disability worldwide. Although it is known that the complement and coagulation systems interact, no studies have investigated the specific role or mechanisms of lectin-mediated coagulation in vivo. FeCl(3)

Ebola viruses constitute a newly emerging public threat because they cause rapidly fatal hemorrhagic fevers for which no treatment exists, and they can be manipulated as bioweapons. We targeted conserved N-glycosylated carbohydrate ligands on viral envelope surfaces using novel immune therapies.

Alphaviruses and flaviviruses are important human pathogens that include Chikungunya virus (CHIKV), Dengue virus (DENV), and Zika virus (ZIKV), which can cause diseases in humans ranging from arthralgia to hemorrhagic fevers and microcephaly. It was previously shown that treatment with surface layer

Human serum albumin (HSA) is responsible for 80% of the colloid osmotic pressure of plasma (25-33 mmHg). Its main clinical use is in maintaining colloid oncotic pressure and increasing circulating plasma volume with the typical dosage in excess of 10 g per dose. HSA is isolated by fractionating

Internalization of peptides by antigen presenting cells is crucial for the initiation of the adaptive immune response. Mannosylation has been demonstrated to enhance antigen uptake through mannose receptors, leading to improved immune responses. In this study we test the effect of surface

An extract from the parenchyma of Aloe barbadensis Miller shown to contain long chain polydispersed beta (1,4)-linked mannan polymers with random O-acetyl groups (acemannan, Carrisyn) was found to initiate the phagocyte production of monokines that supported antibody dependent cellular cytotoxicity
