PD‐L1 on Tumor‐Derived Extracellular Vesicles Induces CD8+ T Cell Terminal Exhaustion and Mediates Anti‐PD‐1 Resistance in Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
Immunotherapy fails in head and neck squamous cell carcinoma (HNSCC) due to terminally exhausted T (Texterm) cells. Tumor‐derived PD‐L1+ extracellular vesicles promote CD8‐Texterm cells differentiation by upregulating BATF. Stromal Texterm density serves as a potent biomarker for predicting immunotherapy resistance, highlighting a novel EV‐mediated ...

Degranulation Inhibitors from Medicinal Plants in Antigen-Stimulated Rat Basophilic Leukemia (RBL-2H3) Cells.

Chemical and pharmaceutical bulletin, 2016
Mast cells and basophils play important roles in both immediate- and late-phase reactions of type 1 allergy. Histamine, which is released from mast cells and basophils stimulated by an antigen or degranulation inducers, is usually determined as a ...

Repurposing of Chemokine Antagonists for Combined Phase‐Resolved Spinal Cord Injury Treatment

Advanced Science, EarlyView.
Spinal cord injury (SCI) in mammals is accompanied by a massive cytokine storm in cerebrospinal fluid, mainly driven by CXCL1, IL‐6, and CCL2‐5. Sub‐acute phase is mostly associated with IL‐2, IL‐7, CCL22, and CX3CL1, whereas TNFα and IL17α permanently persists in CNS even weeks following SCI.

CREB Is Critically Implicated in Skin Mast Cell Degranulation Elicited via FcεRI and MRGPRX2

Cells
Skin mast cells (MCs) mediate acute allergic reactions in the cutaneous environment and contribute to chronic dermatoses, including urticaria, and atopic or contact dermatitis.

Cloned mouse cells with natural killer function and cloned suppressor T cells express ultrastructural and biochemical features not shared by cloned inducer T cells. [PDF]

, 1983
We have examined the morphology, cytochemistry, and biochemistry of mouse leukocyte subsets by analyzing cloned leukocyte populations specialized to perform different immunologic functions.

Predominance of weakly cytotoxic, T-betLowEomesNeg CD8+ T-cells in human gastrointestinal mucosa: implications for HIV infection. [PDF]

, 2017
The gastrointestinal mucosa is an important site of HIV acquisition, viral replication, and pathogenesis. Immune cells in mucosal tissues frequently differ in phenotype and function from their non-mucosal counterparts.

In Situ Assembly of Transformable Monopeptide on Activated Neutrophils Attenuates NETs‐Induced Hepatocellular Carcinoma Metastasis by Disrupting NE Nuclear Translocation

Advanced Science, EarlyView.
Activated neutrophils release extracellular traps (NETs) that promote tumor metastasis. FTP‐NPs are develpoed, a peptidic nanomaterial that binds NE on neutrophil membranes, forming NE‐fibril clusters that deactivate NE and prevent NETs formation. This strategy reduces metastasis and enhances the anti‐tumor immune response by targeting NE subcellular ...

Mast cell activation triggered by SARS-CoV-2 causes inflammation in brain microvascular endothelial cells and microglia

Frontiers in Cellular and Infection Microbiology
SARS-CoV-2–induced excessive inflammation in brain leads to damage of blood–brain barrier, hypoxic-ischemic injury, and neuron degeneration. The production of inflammatory cytokines by brain microvascular endothelial cells and microglia is reported to be

Human mast cells exhibit an individualized pattern of antimicrobial responses

Immunity, Inflammation and Disease, 2020
Introduction Mast cells (MCs) are tissue‐resident immune cells implicated in antibacterial responses. These include chemokine secretion, degranulation, and the release of mast cell‐extracellular traps, which are primarily dependent on reactive oxygen ...

Development of Artificial Intelligence for Quantitative Assessment of Nasal Inflammatory Cytology in Chronic Rhinitis by Whole‐Slide Images

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinitis (CR) is currently recognized as a syndrome that manifests in different phenotypes. We aimed to establish an artificial intelligence system (quantitative assessment of nasal inflammatory cytology, QANIC) on the basis of whole‐slide images (WSIs) to enable quantitative assessment of nasal inflammatory cells.
