T follicular helper cells drive functionally distinct lymphoid and lung resident germinal centres and limit allergic airway disease. Faith I Uwadiae

by

Mucosal Immunol. 2025 Oct 15:S1933-0219(25)00107-2. doi: 10.1016/j.mucimm.2025.10.005. Online ahead of print. ABSTRACT T follicular helper cells (TFH) play a central role in orchestrating antibody mediated immunity. Despite the importance of antibody responses, especially allergen-specific IgE, in allergic airway diseases (AAD) such as asthma, the precise role TFH play in AADs has remained elusive. Using a … Read more

Neutrophil-chemoattractant CXCL5 increases lung barrier permeability in acute lung injury. Sarah Berger

by

Mucosal Immunol. 2025 Oct 9:S1933-0219(25)00105-9. doi: 10.1016/j.mucimm.2025.10.003. Online ahead of print. ABSTRACT Acute lung injury is a common complication of pneumonia, with disease severity linked to inflammatory cell recruitment and lung barrier dysfunction. In this study, we investigate the role of neutrophil-chemoattractant CXCL5 in lung barrier function and inflammation. We examined CXCL5 in patients with … Read more

Viral destruction of the olfactory mucosa elicits immune residence, bone metaplasia, and long-term smell loss. Skye Y Tracey

by

Mucosal Immunol. 2025 Oct 9:S1933-0219(25)00104-7. doi: 10.1016/j.mucimm.2025.10.002. Online ahead of print. ABSTRACT The upper airway is comprised of two distinct mucosal surface tissues, the respiratory mucosa (RM) and the olfactory mucosa (OM), both of which are constantly being exposed to airborne pathogens. The olfactory mucosa is responsible for detecting and conveying odorant information into the … Read more

Epididymitis promotes formation of tertiary lymphoid organs in the cauda epididymidis. Hiba Hasan

by

Mucosal Immunol. 2025 Oct 9:S1933-0219(25)00103-5. doi: 10.1016/j.mucimm.2025.10.001. Online ahead of print. ABSTRACT Uropathogenic Escherichia coli is a common pathogen that affects the cauda epididymidis, causing interstitial edema, epithelial damage, leukocyte infiltration, and fibrosis. Despite antibiotic treatment, up to 20 % of patients develop abscesses in the cauda epididymidis, and 40 % experience low sperm counts. … Read more

Group 3 innate lymphoid cell-derived CSF2 tunes homeostasis of tissue macrophages and neutrophils. S L Tai

by

Mucosal Immunol. 2025 Oct 7:S1933-0219(25)00106-0. doi: 10.1016/j.mucimm.2025.10.004. Online ahead of print. ABSTRACT Group 3 innate lymphoid cells (ILC3) are tissue-resident lymphocytes that contribute to tissue and immune homeostasis. Alterations in ILC3 development or deficiency in their effector functions have beneficial and detrimental outcomes on chronic inflammation, host defense and barrier integrity. Although research has progressed … Read more

Novel loss-of-function intronic mutation in ELF4 is associated with intestinal autoinflammation. Chunyang Tian

by

Mucosal Immunol. 2025 Sep 24:S1933-0219(25)00097-2. doi: 10.1016/j.mucimm.2025.09.007. Online ahead of print. ABSTRACT Monogenic errors of immunity can present with inflammatory bowel disease (IBD)-like enteropathy. We describe an adolescent with IBD- and Behçet’s-like phenotype, resulting from an intronic, loss of function mutation (c.248-7G > A) in ELF4, an X-linked transcription factor executing multiple biological functions. The … Read more

IgA-dependent cell phagocytosis of HIV-infected cells elicits cross-presentation to CD8+T cells and immune memory in effector monocytes. Andrea Cottignies-Calamarte

by

Mucosal Immunol. 2025 Sep 18:S1933-0219(25)00094-7. doi: 10.1016/j.mucimm.2025.09.004. Online ahead of print. ABSTRACT Mucosal IgA antibodies are the first defence against mucosal infections. Besides targeting specific antigens by their Fab-region, IgA also mediates antiviral functions via their Fc-domain, allowing infected cells destruction by antibody-dependent cellular phagocytosis (ADCP). Passive immunisation with anti-HIV-1 IgG protected Non-Human Primates in … Read more

Rhinovirus C15 infection induces airway epithelial cell remodeling and robust inflammatory responses: Potential implications for airway obstruction in children. Yiran Li

by

Mucosal Immunol. 2025 Sep 18:S1933-0219(25)00092-3. doi: 10.1016/j.mucimm.2025.09.002. Online ahead of print. ABSTRACT Despite recognition of rhinovirus-C (RV-C) as a cause of severe respiratory exacerbations, little is known about the pathogenesis of RV-C infections. We infected mucociliary-differentiated primary tracheobronchial epithelial cells with RV-C15 or RV-A16. Initial RNASeq data showed that, compared to RV-A16, RV-C15 decreased expression … Read more

Akkermansia muciniphila ameliorates salmonella-induced colitis and intestinal fibrosis. Abdulhadi Suwandi

by

Mucosal Immunol. 2025 Sep 15:S1933-0219(25)00095-9. doi: 10.1016/j.mucimm.2025.09.005. Online ahead of print. ABSTRACT Salmonella enterica serovar Typhimurium is a food-borne pathogen and a major cause of gastroenteritis in humans. The intestinal microbiota provides colonization resistance to enteric pathogens such as S. Typhimurium. Akkermansia muciniphila is an anaerobic bacterium commonly found in the intestinal tract of humans … Read more
