ABSTRACT Macrophages play important roles in lung homeostasis and disease by interacting with their surrounding tissue microenvironment. Accordingly, macrophage metabolism and local metabolites shape immune responses in the lung. Here, I review the metabolic regulation of lung macrophages and regulation of lung immunity by … Read more

ABSTRACT Mycoplasma pneumoniae (MP) infection directly damages lung tissue and triggers dysregulated immune responses, yet the immunopathology underlying the severe pneumonia remains unknown. Here we analyzed cellular and molecular features in the peripheral blood and bronchoalveolar lavage fluid from patients to define the systemic … Read more

ABSTRACT Chronic airway inflammation is a central driver of asthma pathogenesis, in which macrophages play a pivotal role. While autophagy is known to regulate macrophage function, the specific molecular mechanisms linking autophagy to allergic airway inflammation remain unclear. Here, we identify macrophage sirtuin 6 … Read more

ABSTRACT Infection with Mycobacterium tuberculosis can cause diverse lesions, such as necrotic pneumonia, which can contribute to tuberculosis progression and transmission between individuals. Despite advances in understanding the role of ATP-gated P2RX7 ion channels in the development of severe forms of the disease, the … Read more

ABSTRACT The development of treatments for ulcerative colitis (UC) has seen significant advancements over recent years, focusing on new drugs, innovative approaches, and a deeper understanding of the disease mechanisms. Few however have been able to restore natural tolerance. The hookworm-derived recombinant Anti-Inflammatory Protein … Read more

ABSTRACT Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by epithelial barrier dysfunction and type 2-dominant inflammation, yet the upstream regulatory mechanisms linking epithelial remodeling and immune activation remain poorly understood, and reliable biomarkers for eosinophilic CRSwNP (EOS CRSwNP) are limited. This study investigated … Read more

ABSTRACT Post-COVID syndrome (PCS) is a complex condition that can emerge after recovery from SARS-CoV-2 infection, even in young, healthy individuals with mild acute illness. While the underlying mechanisms remain unclear, viral persistence and immune dysregulation are considered key contributors. This study investigates whether … Read more

ABSTRACT Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of cutaneous infections, underscoring the need for alternative therapeutic strategies. Catestatin (CST), a neuroendocrine antimicrobial peptide produced by neurons and epithelial cells, has been implicated in skin defense against pathogens such as MRSA, though its … Read more
