Covalent Activation of the C‐type Lectin DC‐SIGN
We introduce the first covalent activators of a C‐type lectin. Using orthogonal functional assays, NMR, MS/MS, and computational modeling, we delineate mechanisms from a functional electrophile‐first screen on dendritic cell‐specific intercellular adhesion molecule‐3‐grabbing non‐integrin (DC‐SIGN) that yields two modes: N‐hydroxysuccinimide (NHS ...

Calcium‐Independent Activation of an Allosteric Network in Langerin by Heparin Oligosaccharides [PDF]
AbstractThe C‐type lectin receptor Langerin is a glycan‐binding protein that serves as an uptake receptor on Langerhans cells and is essential for the formation of Birbeck granules. Whereas most Langerin ligands are recognized by a canonical Ca2+‐dependent binding site, heparins have been proposed to make additional contacts to a secondary, Ca2 ...

Filaggrin-null mutations are associated with increased maturation markers on Langerhans cells [PDF]
Background Mutations in the gene encoding filaggrin (FLG), an epidermal structural protein, are the strongest risk factor identified for the development of atopic dermatitis (AD).

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Langerhans cell histiocytosis (LCH) is characterized by the accumulation of Langerin (CD207)-expressing histiocytes. Mutational activation of mitogen-activated protein kinase pathway genes, in particular BRAF, drives most cases. To test whether activated

Langerin-Heparin Interaction: Analysis of the Binding to the Non-Lectin Site [PDF]
Langerin is a C-type lectin involved in the immune response that forms a trimer in its active form. It can interact with carbohydrates using 2 sites with different selectivity, the C-lectin site, a Ca2+-mediated binding, and the cleft between chains. Here we report the complementary analysis of the interaction between a heparin-like hexasaccharide 1 ...

The PDK1-Rsk signaling pathway controls Langerhans cell proliferation and patterning [PDF]
Langerhans cells (LC), the dendritic cells of the epidermis, are distributed in a distinctive regularly spaced array. In the mouse, the LC array is established in the first few days of life from proliferating local precursors, but the regulating ...

ALK‐Positive Histiocytosis With Unilateral Breast Involvement: A Case Report
ABSTRACT APH is a rare disorder characterized by the proliferation of ALK‐expressing histiocytes with variable anatomical involvement; however, mammary involvement is exceptionally rare. A 32‐year‐old woman presented with a painless right breast mass. Ultrasound identified a 9 × 8 mm hypoechoic nodule, categorized as BI‐RADS 4A.

Langerhans cells and more: langerin‐expressing dendritic cell subsets in the skin [PDF]
Summary: Langerhans cells (LCs) are antigen‐presenting dendritic cells (DCs) that reside in epithelia. The best studied example is the LC of the epidermis. By electron microscopy, their identifying feature is the unique rod‐ or tennis racket‐shaped Birbeck granule.
