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.

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 ...

A serine protease isolated from the bristles of the Amazonic caterpillar, Premolis semirufa, is a potent complement system activator. [PDF]

PLoS ONE, 2015
The caterpillar of the moth Premolis semirufa, commonly named pararama, is found in the Brazilian Amazon region. Accidental contact with the caterpillar bristles causes an intense itching sensation, followed by symptoms of an acute inflammation, which ...

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Complement receptor C3aR marks heterogeneous tumor‐associated macrophage states associated with improved survival in IDH‐wildtype glioblastoma

Brain Pathology, EarlyView.
C3aR expression in IDH‐wildtype glioblastoma is predominantly associated with the myeloid/macrophage compartment and heterogeneous macrophage states. C3aR‐high tumors are enriched among MGMT promoter‐methylated tumors and show improved overall survival, although the prognostic association requires independent validation.

Kininase I drives angiotensin II‐induced hypertension through activation of the bradykinin B1 receptor

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Kininase I, comprising carboxypeptidase N (CPN) and carboxypeptidase M, regulates kinin activity and is up‐regulated during injury, inflammation and immune activation. Under these conditions, kininase I converts bradykinin and kallidin into des‐Arg kinins, primary endogenous agonists of the bradykinin B1 receptor (R ...

A First‐in‐Japanese Phase 1, Double‐Blind, Placebo‐Controlled, Parallel‐Cohort Study of Sefaxersen, an Antisense Oligonucleotide Targeting Complement Factor B, in Healthy Participants [PDF]

Clinical Pharmacology in Drug Development
Abstract Increased activity in the complement alternative pathway (AP) plays a key role in diseases such as IgA nephropathy (IgAN). This first‐in‐Japanese double‐blind Phase 1 study investigated the pharmacokinetics (PK), pharmacodynamics (PD), safety, and tolerability of sefaxersen (RO7434656), an antisense oligonucleotide targeting complement factor ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Complement System Inhibition Modulates the Pro-Inflammatory Effects of a Snake Venom Metalloproteinase

Frontiers in Immunology, 2019
Envenomation by Bothrops snakes causes prominent local effects, including pain, oedema, local bleeding, blistering and necrosis, and systemic manifestations, such as hemorrhage, hypotension, shock and acute renal failure.
