ST6GAL1‐Mediated Sialylation Stabilizes PD‐L1 and Drives Immunosuppressive Tumor Microenvironment in Colorectal Cancer

Advanced Science, EarlyView.
ST6GAL1 plays a critical role in tumor progression and immune regulation in colorectal cancer (CRC). Its depletion significantly suppresses the malignant phenotype of CRC cells and enhances the efficacy of anti‐PD‐L1 therapy. High ST6GAL1 expression promotes an immune‐activated tumor microenvironment (TME), characterized by increased infiltration of ...

Cloning and characterization of a mannose binding C-type lectin gene from salivary gland of Aedes albopictus

Parasites & Vectors, 2014
Background The studies on sialomes have shown that hematophagous mosquito saliva consists of a lot of pharmacologically active proteins, in which C-type lectins have been identified and regarded as an important component of saliva.

Levels of complexity in pathogen recognition by C-type lectins

Current Opinion in Immunology, 2005
In pathogen recognition by C-type lectins, several levels of complexity can be distinguished; these might modulate the immune response in different ways. Firstly, the pathogen-associated molecular pattern repertoire expressed at the microbial surface determines the interactions with specific receptors.

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity

Advanced Science, EarlyView.
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...

Homeostasis of Gut Microbiota Protects against Susceptibility to Fungal Pneumonia

Advanced Science, EarlyView.
Fungal pneumonia induces inflammation, shown by heightened IL‐6, IL‐1β, TNF‐α levels and a growth in Staphylococcus in the alveolar flora. The gut microbiota, acting through the gut‐lung axis via blood, impacts fungal pneumonia susceptibility by altering lung metabolism and inflammatory responses.

Crotacetin, a novel snake venom C-type lectin, is homolog of convulxin

Journal of Venomous Animals and Toxins including Tropical Diseases, 2005
Snake venom (sv) C-type lectins encompass a group of hemorrhagic toxins, which are able to interfere with hemostasis. They share significant similarity in their primary structures with C-type lectins of other animals, and also present a conserved ...

C-type lectins in immunity to Mycobacterium tuberculosis

Frontiers in Bioscience, 2011
Tuberculosis (TB) remains one of the leading causes of death due to a single infectious agent, Mycobacterium tuberculosis, with nearly 2 million deaths per year (1). Most individuals exposed to the bacillus develop a nonpathological form, latent TB, with only a small minority (5 to 10%) developing active disease.

HERV‐K TM Subunit Elicits CD8+ T Cell Anergy and Tumor Immune Evasion via Targeting CD3 Coreceptor ε in AML and PDAC

Advanced Science, EarlyView.
Novel viral immune checkpoint K‐TM subunit is aberrantly expressed in CD8+ T cells and enriched in sera of cancer patients, inducing CD8+ T cell anergy and eliciting potent tumor immune escape in mouse model. Mechanistically, K‐TM directly targets and induces the phosphorylation of CD3ε receptor.

Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity

Advanced Science, EarlyView.
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...
