About this book
English EN. English en. Deutsch de. Their carbohydrate preference is dependent on the amino acid sequence in the CRD domain and on the ability and flexibility of the CRD domain to accommodate sugar moieties that are located at different distances from each other in the glycoconjugate. Although microbial and vertebrate cells are able to produce similar polysaccharide chains, the density of carbohydrates on microbes is much higher compared to vertebrate cells.
Pathogen or Damage-activated C-Type Lectin Pathways: R&D Systems
Despite this difference, carbohydrates present on both cell types can be recognized by the CLRs. These receptors are predominantly expressed by antigen presenting cells such as dendritic cells. In addition to the Toll-like receptor family, CLRs function as pattern recognition receptors by recognizing glycosylated patterns on pathogens. This usually results in internalization of the pathogen, lysosomal degradation and subsequent loading of pathogen-derived peptides into major histocompatibility complex molecules for antigen presentation.
Comparative molecular characterization of C-type lectin receptors activated by ß-glucans
However, several pathogens have developed ways to exploit the CLRs to evade immune eradication by for example escaping from the lysosomal degradation pathway or by inducing anti-inflammatory cytokines. When CLRs bind endogenous glycosylated ligands they mediate several processes like cellcell adhesion and clearance of aberrant cells like tumor cells or apoptotic cells. In addition, CLR ligands are frequently exposed in complex structures that simultaneously bind different CLRs and other PRRs, which lead to integration of heterologous signaling among diverse receptors.
Herein, we will review how sensing by myeloid CLRs and crosstalk with heterologous receptors is modulated by many factors affecting their signaling and resulting in differential outcomes for immunity and inflammation. Finding common features among those flexible responses initiated by diverse CLR-ligand partners will help to harness CLR function in immunity and inflammation.
