Article Abstract

Eosinophils are a type of granulocyte named after the presence of their eosin-stained granules. Traditionally, eosinophils have been best known to play prominent roles in anti-parasitic responses and mediating allergic reactions. Knowledge of their behaviour has expanded with time, and they are now recognized to play integral parts in the homeostasis of gastrointestinal, respiratory, skeletal muscle, adipose, and connective tissue systems. As such, they are implicated in a myriad of pathologies, and have been the target of several medical therapies. This review focuses on the lifespan of eosinophils, from their origins in the bone marrow, to their tissue-resident role. In particular, we wish to highlight the functions of eosinophils in non-mucosal tissues with skeletal muscle and the adipose tissues as examples, and to discuss the current understanding of their participation in diseased states in these tissues.

Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.

Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.

Mast cells (MCs) rapidly adapt to the microenvironment due to the plethora of cytokine receptors expressed. Understanding microenvironment-primed immune responses is essential to elucidate the phenotypic/functional changes MCs undergo, and thus understand their contribution to diseases and predict the most effective therapeutic strategies. We exposed primary human MCs to cytokines mimicking a T1/pro-inflammatory (IFNγ), T2/allergic (IL-4 + IL-13), alarmin-rich (IL-33) and pro-fibrotic/pro-tolerogenic (TGFβ) microenvironment.

Background: Eosinophilic pleural effusion (EPE), characterized by atypical symptoms and rarity, is easily over-looked and misdiagnosed.

Methods: The patient underwent comprehensive routine laboratory tests including blood analysis and pleural effusion examination, along with B-ultrasound and computed tomography (CT) imaging. Based on combined evaluation of the epidemiological history, serum-specific parasite antibody detection and targeted Next-Generation Sequencing were performed on the clinical specimens.

Taenia crassiceps (Zeder, 1800), a zoonotic cestode with a wide geographical distribution, utilises canids as definitive hosts and small rodents as intermediate hosts. However, accidental infections in non-human primates, particularly in captive lemurs, have been increasingly documented. In this case report, we describe the first documented case of cysticercosis caused by the larval stage of T.

Wiskott-Aldrich Syndrome (WAS) is an X-linked immunodeficiency characterized by eczema, microthrombocytopenia, and recurrent infections. Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory disorder involving various organs. We present a 34-year-old male with WAS who developed cervical lymphadenopathy and parotid gland swelling.
