Activation of P2X7 Receptors in Peritoneal and Meningeal Mast Cells Detected by Uptake of Organic Dyes: Possible Purinergic Triggers of Neuroinflammation in Meninges

Frontiers in Cellular Neuroscience, 2019
Extracellular ATP activates inflammasome and triggers the release of multiple cytokines in various immune cells, a process primarily mediated by P2X7 receptors.

Piecemeal degranulation in human tumour pheochromocytes

Journal of Anatomy, 2005
AbstractPiecemeal degranulation (PMD) has been recognized in two cases of human pheochromocytoma from the adrenal medulla, which were studied by transmission electron microscopy. Tumour pheochromocytes presented a highly characteristic cytoplasmic admixture of normal resting granules, swollen granules with eroded matrices and enlarged empty containers.

Persistent Interleukin‐18 Fuels Expansion of CD38+HLA‐DR+CD8+ T Cells in Still Disease and Macrophage Activation Syndrome

Arthritis &Rheumatology, EarlyView.
Objective Still disease (SD) is an autoinflammatory disorder characterized by remarkably high interleukin‐18 (IL‐18) levels. Increasing evidence suggests that adaptive immunity also contributes to its pathogenesis, particularly in refractory courses. Macrophage activation syndrome (MAS), one of SD's most severe complications, is associated with further

Treatment‐Driven Peripheral Blood Transcriptomic Remodeling and Baseline Predictors of ESSDAI and STAR Response to B Cell Therapy in Sjögren's Disease

Arthritis &Rheumatology, EarlyView.
Graphical Abstract Objective This study aimed to characterize whole blood transcriptomic profiles in adults with active Sjögren's disease (SjD) treated with anti‐CD20 or B lymphocyte stimulator/BAFF inhibition, identify markers of clinical response, and define inflammatory pathways linked to nonresponse. Methods Whole blood RNA sequencing was performed

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.

Eosinophil secretion of granule-derived cytokines

Frontiers in Immunology, 2014
Eosinophils are tissue-dwelling leukocytes, present in the thymus, and gastrointestinal and genitourinary tracts of healthy individuals at baseline, and recruited, often in large numbers, to allergic inflammatory foci and sites of active tissue repair ...

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 ...

Pentoxifylline dose finding trial in preterm neonates with suspected late onset sepsis (PTX‐trial)

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study (PTX‐trial) is to determine the optimal dose of pentoxifylline (PTX) in preterm neonates (gestational age < 30 weeks) with (suspected) late onset sepsis (LONS). Methods The PTX‐trial is a prospective multicentre open‐label sequential dose‐optimization study with an adapted continual reassessment method.

Garcinol A Novel Inhibitor of Platelet Activation and Apoptosis

Toxins, 2019
Garcinol, an anti-inflammatory and anti-carcinogenic polyisoprenylated benzophenone isolated from Garcinia plants, stimulates tumor cell apoptosis and suicidal erythrocyte death, but supports the survival of hepatocytes and neurons.
