Rationale for targeting complement in COVID‐19

EMBO Molecular Medicine, 2020
A novel coronavirus, SARS‐CoV‐2, has recently emerged in China and spread internationally, posing a health emergency to the global community. COVID‐19 caused by SARS‐CoV‐2 is associated with an acute respiratory illness that varies from mild to the life ...

Cancer Stem Cells Shift Metabolite Acetyl‐Coenzyme A to Abrogate the Differentiation of CD103+ T Cells

Advanced Science, EarlyView.
Lei et al. demonstrate that cancer stem cells (CSCs) play a pivotal role in impairing the differentiation of CD103+ T cells in patients with non‐small‐cell lung cancer. The key mechanism involves CSC‐derived acetyl‐CoA, which disrupts CD103+ T cell differentiation by sequentially inducing acetylation and ubiquitination of the Blimp‐1 protein. Targeting

GlycoChat Uncovers Glycan–Lectin Circuits in the Tumor Microenvironment of Pancreatic Cancer

Advanced Science, EarlyView.
Aberrant glycosylation drives cancer progression, yet its role in the tumor microenvironment remains unclear. We developed GlycoChat to map glycan–lectin circuits at single‐cell resolution. We discovered that cancer cells induce immunosuppressive macrophage differentiation and impair phagocytosis through interactions with CLEC10A and SIGLEC3 ...

GbWAKL20 Phosphorylates GbNFYB8 to Modulate Verticillium Wilt Resistance in Cotton

Advanced Science, EarlyView.
Wall‐associated receptor‐like kinases (WAKLs) play pivotal roles in extracellular–intracellular signal transduction. Upon sensing Verticillium dahliae infestation at the plasma membrane, GbWAKL20 accumulates and transmits signals to the nucleus via endoplasmic reticulum‐mediated Golgi vesicle transport.

GALNT10 Affects O‐Glycosylation of IGFBP7 to Promote Tumor Vascular Remodeling and Metastasis of Ovarian Cancer

Advanced Science, EarlyView.
The glycosyltransferase GALNT10 facilitates ovarian cancer metastasis through the induction of tumor cell EMT and tumor vascular dysfunction. GALNT10 enhanced the extracellular secretion of IGFBP7 through O‐GalNAc glycosylation modification at the T188 site, which subsequently interacts with CD93 on endothelial cells, leading to vascular remodeling ...

The Human Platelet as an Innate Immune Cell: Interactions Between Activated Platelets and the Complement System

Frontiers in Immunology, 2019
Platelets play an essential role in maintaining homeostasis in the circulatory system after an injury by forming a platelet thrombus, but they also occupy a central node in the intravascular innate immune system.

The lectin pathway of complement activation

, 2007
The complement system is an important immune system mechanism involved in both the recognition and elimination of invading pathogens. It is activated by three different pathways: The classical pathway, which relies on binding of C1, and results in the cleavage of C4 and C2 through activation of C1r and C1s; the alternative pathway that relies on the ...

Core Fucosylation Represses SMURF1‐Dependent Degradation of CD47 to Promote Tumor Immune Evasion

Advanced Science, EarlyView.
FUT8‐mediated core fucosylation of CD47 at N111 blocks SMURF1 binding and reduces CD47 ubiquitination and degradation. Blocking N111 glycosylation reduces CD47 expression and promotes macrophage phagocytosis of tumor cells. Furthermore, ablating CD47 core fucosylation boosts CD103+ dendritic cells (DCs) infiltration, increases natural killer (NK) cell ...

Identification of a Ficolin-like Serum Lectin of the Common Carp as a Novel Homologue of Mammalian Microfibrillar-Associated Protein 4

Journal of Marine Science and Engineering
Serum lectins in vertebrates play crucial roles in innate immunity as recognition molecules for pathogen-associated molecular patterns (PAMPs). In mammals, two major lectins, mannose-binding lectin (MBL) and ficolin, both containing N-terminal collagen ...

Nanoparticle Immunoadjuvant Complexes Augment Germinal Center Responses to Vaccination

Advanced Science, EarlyView.
Scaffolding IL‐21 on the surface of a self‐assembling nanoparticle immunogen drives improved germinal center and humoral immune responses. These nanoparticle immunoadjuvant complexes (NICs) functionally modulate the germinal center driving improved somatic hypermutation and antibody maturation, suggesting this platform has potential utility as a ...
