Basophils in Immunity: Activation Pathways, Roles in Allergy and AllergoOncology and Application of the Basophil Activation Test

Allergy, EarlyView.
ABSTRACT Basophils, the least abundant leukocytes, are increasingly recognised as potent immunomodulators. Upon activation, they rapidly release preformed granule‐associated mediators including histamine and lipid mediators such as LTC4, while cytokine production occurs over a longer timescale, contributing to downstream immune responses.

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

Nomenclature on Immune‐Mediated Drug Reactions: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Over the past several decades, there have been significant advances in our understanding of both immunological and pharmacological mechanisms of adverse drug reactions (ADRs). Immune‐mediated drug reactions (IMDRs) represent a small proportion of ADRs and are caused by a pathological activation of the immune system or inflammatory pathways ...

Understanding the Type 2 Immunity: An Evolving View Beyond Allergic Diseases

Allergy, EarlyView.
ABSTRACT Type 2 (T2) immunity is classically associated with defense against helminths and environmental threats, from a physiological perspective, and with allergies and eosinophilic inflammatory diseases, in a pathological sense. However, growing evidence reveals that T2 pathways also support other essential homeostatic functions, including tissue ...

Structure of the complex of leech-derived tryptase inhibitor (LDTI) with trypsin and modeling of the LDTI–tryptase system

, 1997
Background: Tryptase is a trypsin-like serine proteinase stored in the cytoplasmic granules of mast cells, which has been implicated in a number of mast cell related disorders such as asthma and rheumatoid arthritis.

Single‐Cell Profiling Links T‐Cell Accumulation and TH2/TH17 Dynamics to Eosinophilic Esophagitis (EoE) Activity in Children

Allergy, EarlyView.
Active EoE is associated with more and deeper epithelial eosinophil, mast cell, and T cell infiltration; inactive EoE resembles controls. During remission, PPI treatment leaves more tissue resident CD3+ T‐cells than TS. In active EoE, TH2 cells, IL‐10hi Tregs, and CD8+ cytotoxic T cells are enriched, while TH17 cells are relatively depleted.

Comparison of the diagnostic performance of tryptase and histamine for perioperative anaphylaxis: A multicenter prospective study

Allergology International
Background: Diagnosing perioperative anaphylaxis (POA) is often challenging. Although a guideline recommends measuring tryptase rather than histamine, there is little evidence for this.

Diagnostic Delay in Eosinophilic Granulomatosis With Polyangiitis: Clinical Predictors and Implications for Earlier Recognition

Allergy, EarlyView.
This study aimed to assess diagnostic delay among patients with eosinophilic granulomatosis with polyangiitis (EGPA) and identify clinical characteristics associated with delayed recognition. EGPA diagnosis was delayed by nearly five years from symptom onset in this single‐center cohort.

Alpha tryptase: Potential roles in inflammation distinct from those of b-tryptase

, 2010
RATIONALE: Tryptases are among the most abundant products of the humanmast cell. Beta-tryptase has emerged as an important mediator of allergicinflammation.
