Alarmins link neutrophils and dendritic cells [PDF]

Trends in Immunology, 2009
Neutrophils are the first major population of leukocyte to infiltrate infected or injured tissues and are crucial for initiating host innate defense and adaptive immunity. Although the contribution of neutrophils to innate immune defense is mediated predominantly by phagocytosis and killing of microorganisms, neutrophils also participate in the ...

The production, function, and clinical applications of IL-33 in type 2 inflammation-related respiratory diseases

Frontiers in Immunology
Epithelial-derived IL-33 (Interleukin-33), as a member of alarm signals, is a chemical substance produced under harmful stimuli that can promote innate immunity and activate adaptive immune responses.

Sequence of Immunological Events During IgE‐Mediated Allergic Reactions to Food

Allergy, EarlyView.
ABSTRACT Food allergies (FA) represent a significant global health burden. Upon allergen re‐exposure, allergic patients exhibit a sequence of symptoms that vary in terms of affected organ systems, severity, time of onset and allergen reactivity thresholds.

IL-33 in Rheumatic Diseases

Frontiers in Medicine, 2021
Interleukin-33 (IL-33) is a nuclear factor mainly expressed in barrier epithelium, endothelial cells, and fibroblast reticular cells. Some inflammatory cells also express IL-33 under certain conditions.

Targeting Immunologic Pathways in Eosinophilic Granulomatosis With Polyangiitis: Translating Emerging Evidence Into Clinical Practice

Allergy, EarlyView.
ABSTRACT Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare and potentially life‐threatening systemic, inflammatory disease with multi‐organ manifestations, variable presentation and complex pathology. Multiple interconnected immunological pathways are implicated in EGPA pathology, including a type‐2 immune response driving predominantly ...

Successful Application of the Mast Cell Activation Test in Immediate Hypersensitivity to Amoxicillin

Allergy, EarlyView.
This study included 28 amoxicillin‐allergic patients and 11 healthy exposed controls. Mast cells were differentiated from CD34+ progenitors over 8 weeks using cytokine cocktails. The mast cell activation test involved sensitization with patient or control sera and stimulation with free amoxicillin or G4/G5‐AXO dendrimers with successfully activated ...

Redox-control of the alarmin, Interleukin-1α

Redox Biology, 2013
The pro-inflammatory cytokine Interleukin-1α (IL-1α) has recently emerged as a susceptibility marker for a wide array of inflammatory diseases associated with oxidative stress including Alzheimer's, arthritis, atherosclerosis, diabetes and cancer. In the present study, we establish that expression and nuclear localization of IL-1α are redox-dependent ...

Polypropylene Nanoplastic Exposure to Respiratory Epithelial Barrier‐On‐Chip and Interfacial Interactions With Human Serum Albumin

Allergy, EarlyView.
Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.

Red alert: labile heme is an alarmin [PDF]

Current Opinion in Immunology, 2016
Alarmins are a heterogeneous group of endogenous molecules that signal cellular damage when sensed extracellularly. Heme is an endogenous molecule that acts as a prosthetic group of hemoproteins, such as hemoglobin and myoglobin. When released from damaged red blood cells or muscle cells, oxidized hemoglobin and myoglobin release their prosthetic heme ...

Cell death in the pathogenesis of immune-mediated diseases

Swiss Medical Weekly, 2011
Cell death is a ubiquitous process whose immunological consequences can influence the course of infectious, autoimmune and inflammatory diseases. While cell death has long been dichotomised in terms of apoptosis and necrosis, other forms of death ...
