Mannose-binding lectin (MBL) is present in human serum and plays an important role in innate immunity by binding to carbohydrate on micro-organisms. Whereas the gp120/gp41 of human immunodeficiency virus type 1 (HIV-1) contains numerous N-linked glycosylation sites and many of these sites contain high-mannose glycans which could interact with MBL, the interaction between MBL and primary isolate...

Individuals with low levels of mannan-binding lectin (MBL) appear to be susceptible to infectious diseases. This suggests that substitution therapy with MBL might be a beneficial treatment of patients with MBL deficiency. A production process for an MBL product has been developed from a fraction II+III precipitate obtained by ethanol fractionation of plasma. The MBL process includes three chrom...

Monoclonal B-cell lymphocytosis (MBL) is a recently described medical condition that displays biological similarities to the most common subtype of adult leukemia in the Western world, i.e. chronic lymphocytic leukemia (CLL). Diagnostic criteria have been published with the aim of differentiating between these two entities. The overall prevalence of MBL is at least 100 times higher than that of...

INTRODUCTION Mannose-binding lectin (MBL) constitutes defense against infections when adaptive immune response is compromised. Elevation in serum MBL levels has been shown in patients with kidney failure. We compared serum MBL levels before and after kidney transplant and evaluated association of MBL deficiency with infectious complications in kidney transplant recipients. MATERIALS AND METHO...

INTRODUCTION Mannose-binding lectin (MBL) activates complement system and has been suggested to play a role in vascular complications in diabetics. Carotid intima-media thickness (cIMT) detects subclinical atherosclerosis. We evaluated the association of MBL and IMT in type 2 diabetic (T2DM) patients. METHODS Serum MBL levels and cIMT were measured in a total of 103 diabetics and in 98 age-ma...

OBJECTIVES To evaluate four phenotypic tests for the detection of metallo-beta-lactamase (MBL) production in Pseudomonas aeruginosa in a low MBL prevalence setting. METHODS Sixty clinical isolates of P. aeruginosa resistant to imipenem and/or meropenem and seven MBL-positive control strains were examined by: (i) MBL Etest; (ii) combined imipenem discs supplemented with EDTA (IPM-EDTA); (iii) ...

OBJECTIVE Mannan-binding lectin (MBL) is a complement-activating carbohydrate-recognizing molecule associated with diabetic nephropathy. MBL is associated with all-cause mortality in type 2 diabetes, but whether MBL is associated with mortality in type 1 diabetes remains unknown. We therefore aimed to investigate this. RESEARCH DESIGN AND METHODS We studied an existing 12-year prospective coh...

Binding of mannose-binding lectin (MBL), a C-type lectin, and its associated serine proteases, MASP-1 and MASP-2, to cell surface carbohydrates activates the lectin complement pathway. As MBL plays an important role in innate immunity, it has been cloned and characterized in several species. While the pig may be used as a source of organs/tissues for xenotransplantation, little is known about i...

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. Here, we describe a case-control study that included 569 patients with SARS and 1188 control subjects and used in vitro assays to investigate...
