Size-selective molecular recognition based on a confined DNA molecular sieve using cavity-tunable framework nucleic acids

open access: yesNature Communications, 2020
Size-selective discrimination is an issue in biosensing. Here, the authors report on a size selective DNA nanocage which excludes agents based on size and protects the probes against degradation, and demonstrate the discrimination between mature and ...

Long term seasonal dynamics of Synechococcus population structure in the Gulf of Aqaba, Northern Red Sea

open access: yesFrontiers in Microbiology, 2011
Spatial patterns of marine Synechococcus diversity across ocean domains have been reported on extensively. However, much less is known of seasonal and multiannual patterns of change in Synechococcus community composition.

Interaction Properties of Human Mannan-Binding Lectin (MBL)-Associated Serine Proteases-1 and -2, MBL-Associated Protein 19, and MBL [PDF]

open access: yesThe Journal of Immunology, 2001
Abstract The mannan-binding lectin (MBL) activation pathway of complement plays an important role in the innate immune defense against pathogenic microorganisms. In human serum, two MBL-associated serine proteases (MASP-1, MASP-2) and MBL-associated protein 19 (MAp19) were found to be associated with MBL.

Reconstitution of Opsonizing Activity by Infusion of Mannan‐Binding Lectin (MBL) to MBL‐Deficient Humans [PDF]

open access: yesScandinavian Journal of Immunology, 1998
Mannan‐binding lectin (MBL, previously named mannan‐binding protein, MBP) is a serum collectin, which activates complement upon binding to microbial carbohydrates. This results in opsonization of the micro‐organisms as well as direct complement‐mediated killing.

Mannose-Binding Lectin (MBL) Facilitates Opsonophagocytosis of Yeasts but Not of Bacteria despite MBL Binding [PDF]

open access: yesThe Journal of Immunology, 2008
Abstract Mannose-binding lectin (MBL) is a serum protein of the innate immune system. After binding to a microorganism, MBL in complex with MBL-associated serine proteases activates the complement system, resulting in cleavage of complement factor C3.
