Effects of Secreted Mast Cell Mediators on Retinal Pigment Epithelial Cells: Focus on Mast Cell Tryptase

Mediators of Inflammation, 2017
Numerous mast cells are present in the choroid, but the effects of mast cell mediators on retinal pigment epithelial (RPE) cells are not well understood.

Diagnosing Eosinophilic Chronic Rhinosinusitis in Excised Tissue Using Optical Coherence Tomography

The Laryngoscope, EarlyView.
This study evaluated whether optical coherence tomography (OCT) can quantify eosinophils in excised sinonasal tissue and diagnose eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Counts of globules resembling eosinophils on OCT images strongly correlated with eosinophils per HPF on histology, with a cutoff of 45 globules on OCT imaging ...

EFFECT OF POST MORTEM INTERVAL TOWARD Β-TRYPTASE AND CHYMASE EXPRESSION OF ANAPHYLACTIC HEART MAST CELLS

Journal of Vocational Health Studies, 2023
Background: The effects of post mortem interval on tryptase levels are unclear and have been challenging to quantify due to limited and at times contradictory research.

Bivalent inhibition of human β-tryptase [PDF]

Chemistry & Biology, 2001
Human beta-tryptase is a mast cell specific trypsin-like serine protease that is thought to play a key role in the pathogenesis of diverse allergic and inflammatory disorders like asthma and psoriasis. The recently resolved crystal structure revealed that the enzymatically active tetramer consists of four quasi-identical monomers.

G Protein–Coupled Receptors in Olfactory Signaling and Related Disorders: Mechanisms and Therapeutic Implications

Sensory Neuroscience, EarlyView.
This schematic highlights GPCRs as the central hub of olfactory signaling in health and disease. The central GPCR shows odorant activation and downstream pathways. Surrounding quadrants illustrate four GPCR‐mediated themes: odor perception and adaptation, mucosal immunity and regeneration, memory consolidation via neural circuits, and GPCR‐related ...

Protective role of protease-activated receptor-2 in anaphylaxis model mice.

PLoS ONE
Anaphylaxis is a severe life-threatening hypersensitivity reaction induced by mast cell degranulation. Among the various mediators of mast cells, little is known about the role of tryptase. Therefore, we aimed to elucidate the role of protease-activating

Induction of Mast Cell Accumulation by Tryptase via a Protease Activated Receptor-2 and ICAM-1 Dependent Mechanism

Mediators of Inflammation, 2016
Mast cells are primary effector cells of allergy, and recruitment of mast cells in involved tissue is one of the key events in allergic inflammation. Tryptase is the most abundant secretory product of mast cells, but little is known of its influence on ...

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.

The International Guideline for the Definition, Classification, Diagnosis and Management of Urticaria

Allergy, EarlyView.
ABSTRACT This update and revision of the international guideline for urticaria was developed in accordance with the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is an initiative of the Global Allergy and Asthma Excellence Network (GA2LEN) and its Urticaria and ...
