Mucosal Immunol. 2025 Jan 20:S1933-0219(25)00003-0. doi: 10.1016/j.mucimm.2025.01.003. Online ahead of print. ABSTRACT Intestinal immune homeostasis relies on intestinal epithelial cells (IECs), which provide an efficient barrier, and warrant a state of tolerance between the microbiome and the mucosal immune system. Thus, proper epithelial microbial sensing and handling of microbes is key to preventing excessive immunity, … Read more

It is actively transported onto mucosal surfaces as secretory IgA (sIgA) which plays an integral role in protection against enteric pathogens, particularly in young children. Therapeutic strategies that deliver engineered, potently neutralizing … Read more

ABSTRACT First- and secondhand smokers are at an increased risk for influenza virus (IFV)-related respiratory failure and death. Despite approved influenza antiviral treatments, there is an unmet need for treatments that can improve outcomes in populations at risk for respiratory failure, including tobacco users … Read more

ABSTRACT Immunoglobulin A (IgA), the most abundantly produced antibody at mucosal surfaces, is thought to play key roles in immune responses to respiratory and enteric pathogens and in the regulation of commensal colonization. Low IgA levels have been associated with recurrent infections and immune … Read more

ABSTRACT Mucosal tissues, including those in the respiratory and gastrointestinal tracts, are critical barrier surfaces for pathogen invasion. Infections at these sites not only trigger local immune response, but also recruit immune cells from other tissues. Emerging evidence in mouse models and human samples … Read more

ABSTRACT Inflammatory bowel diseases (IBDs) are characterized by unrestrained innate and adaptive immune responses and compromised intestinal epithelial barrier integrity. Regulatory T (Treg) cells are crucial for maintaining self-tolerance and immune homeostasis in intestinal tissues. Prostaglandin E2 (PGE2), a bioactive lipid compound derived from … Read more

ABSTRACT Diabetes mellitus is associated with an increased risk of pneumonia, often caused by so-called typical and atypical pathogens including Streptoccocus pneumoniae and Legionella pneumophila, respectively. Here, we employed a variety of mouse models to investigate how diabetes influences pulmonary antibacterial immunity. Following intranasal … Read more

ABSTRACT Neuro-immune interactions within barrier organs, such as lung, gut, and skin, are crucial in regulating tissue homeostasis, inflammatory responses, and host defence. Our rapidly advancing understanding of peripheral neuroimmunology is transforming the field of barrier tissue immunology, offering a fresh perspective for developing … Read more

ABSTRACT The precise role of neutrophil-derived reactive oxygen species (ROS) in combating bacterial uropathogens during urinary tract infections (UTI) remains largely unexplored. In this study, we elucidate the antimicrobial significance of NADPH oxidase 2 (NOX2)-derived ROS, as opposed to mitochondrial ROS, in facilitating neutrophil-mediated … Read more
