Syk-coupled C-type lectins in immunity

Trends in Immunology, 2011
The Syk-coupled C-type lectin receptor Dectin-1 was the first non-Toll like receptor described that could mediate its own intracellular signalling. It was initially identified as important for the innate recognition of and response to fungal pathogens but later studies revealed that it is also involved in triggering adaptive immune responses.

Using Synthetic Glycans to Investigate Anti‐Glycan Antibodies and Explore Their Medical Potential

Angewandte Chemie International Edition, EarlyView.
Anti‐glycan antibodies are essential in health and disease. Access to novel glycan structures paves the way for progress in antibody profiling for biomarker discovery, antibody development, and vaccine design. We summarize the strategies to synthesize and utilize synthetic glycans for the development and application of anti‐glycan antibodies in basic ...

Characterization of C-type lectins reveals an unexpectedly limited interaction between Cryptococcus neoformans spores and Dectin-1.

PLoS ONE, 2017
Phagocytosis by innate immune cells is an important process for protection against multiple pathologies and is particularly important for resistance to infection.

Interaction of the capsular polysaccharide A from Bacteroides fragilis with DC-SIGN on human dendritic cells is necessary for its processing and presentation to T cells.

Frontiers in Immunology, 2013
The zwitterionic capsular polysaccharide A (PSA) of Bacteroides fragilis is the first carbohydrate antigen described to be presented in major histocompatibility complex (MHC) class II for the induction of CD4+ T cell responses.

C-Type Lectins in Innate Immunity to Pathogens

Trends in Glycoscience and Glycotechnology, 2004
自然免疫系は感染に対する防御機構の最前線であり、防御機構の始動にとって非常に重要である。侵入した病原体は、樹状細胞 (Dendritic cell: DC) の表面に発現する Toll 様受容体やC型レクチン (CLR) などの病原体認識受容体によって認識される。DCが病原体由来の抗原を捕捉すると、DCには病原体を排除することに特化するような様々な変化が生じる。CLRは病原体の表面や分泌物に存在する糖抗原を特異的に捕捉し、その結果として抗原のプロセシングと提示が行われる。しかし、現在の実験事実はCLRが2つの機能を持つことを示唆している。すなわち、CLRは病原体由来抗原の認識に加え、糖付加を受けた自己抗原の認識機構としても機能しており、恒常性の制御と免疫寛容を誘導するというものである。興味深いことに、

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

C-Type Lectin Receptors

, 2016
C-type lectins, originally defined as proteins binding carbohydrates in a Ca(2+)-dependent manner, form a large family containing soluble and membrane-bound proteins. Among them, those expressed on phagocytes and working as pathogen pattern-recognition receptors were designated as C-type lectin receptors (CLRs), in accordance with Toll-like receptors ...

C-type lectins in immunity: recent developments

Current Opinion in Immunology, 2015
C-type lectin receptors (CLRs) comprise a large superfamily of proteins, which recognise a diverse range of ligands, and are defined by the presence of at least one C-type lectin-like domain (CTLD). Of particular interest are the single extracellular CTLD-containing receptors of the 'Dectin-1' and 'Dectin-2' clusters, which associate with signalling ...

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

Animal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

The C‐type lectin‐like domain superfamily

The FEBS Journal, 2005
The superfamily of proteins containing C‐type lectin‐like domains (CTLDs) is a large group of extracellular Metazoan proteins with diverse functions. The CTLD structure has a characteristic double‐loop (‘loop‐in‐a‐loop’) stabilized by two highly conserved disulfide bridges located at the bases of the loops, as well as a set of conserved hydrophobic and
