Two recent papers have addressed the ever-intriguing question of the role of eosinophils in asthma. Both groups used experimental models of airway inflammation in mice that were gene targeted to selectively ablate the eosinophil lineage. One group found that eosinophils were required for both airway hyperresponsiveness and mucus accumulation. The other demonstrated a 'critical role' for the cell in airway remodelling. The results, although largely confirmatory of previous studies both in mice and humans, put the eosinophil firmly back on the asthma stage and strengthen the case for developing effective eosinophil-depleting agents for clinical use.

Background: In-stent restenosis (ISR) is one of the most significant complications following percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD). Ferroptosis is a novel cell death mode characterized by iron overload and lipid peroxidation. However, the role of ferroptosis in vascular smooth muscle cells (VSMCs) regulating neointimal formation during restenosis remains unclear.

Introduction: Diesel exhaust particles (DEP) have been proven to aggravate asthma pathogenesis. We previously demonstrated that concurrent exposure to house dust mite (HDM) and DEP in mice increases both eosinophils and neutrophils in bronchoalveolar lavage fluid (BALF) and also results in higher levels of neutrophil-recruiting chemokines and neutrophil extracellular trap (NET) formation compared to sole HDM, sole DEP or saline exposure. We aimed to evaluate whether treatment with anti-IL-5 can alleviate the asthmatic features in this mixed granulocytic asthma model.

Background: The COVID-19 (SARS-CoV-2) epidemic has posed a major challenge to global public health, especially in children. Some children may experience secondary infection with Mycoplasma pneumoniae after SARS-CoV-2 infection, which has attracted widespread attention. Studies have shown that eosinophils play an important role in respiratory tract infections and are involved in regulating immune responses and inflammatory processes.

Asthma is a heterogeneous disease characterized by chronic airway inflammation and hyperresponsiveness. A number of immune cells are involved in asthma pathogenesis, such as eosinophils, mast cells, T lymphocytes and neutrophils, as well as airway epithelial cells. Glycolysis plays a crucial role in glucose metabolism, and serves as a bridge between metabolic and inflammatory dysfunction.

This study is aimed at investigating the role of key molecular elements involved in pyroptosis in liver injury caused by exertional heat stroke (EHS). We established a model of EHS-induced liver injury in Sprague-Dawley rats, with a control group (receiving no treatment) for comparison and 12 rats in each group. Alanine transaminase (ALT) and aspartate transaminase (AST) levels in the blood were detected.
