Leptin May Promote Eosinophilic CRSwNP Progression by Enhancing Eosinophil Chemotaxis and Angiogenesis Under a Type 2 Inflammatory Milieu

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyp (CRSwNP) is a heterogeneous Type 2 inflammatory disease characterized by enhanced eosinophilic infiltration. Both innate and adaptive immunity are involved in the onset and progression of CRSwNP.

Probing gene function in thymic epithelial cells

European Journal of Cell Biology, 2012
Thymic epithelial cells (TECs) provide a highly specialized microenvironment for the generation of a functional and self-tolerant T cell repertoire. Much of our current view of TEC biology is derived from gain- or loss-of-function approaches, which have significantly contributed to our understanding of gene function in TEC development and T cell ...

The antigen presentation pathway in medullary thymic epithelial cells, but not that in cortical thymic epithelial cells, conforms to the endocytic pathway [PDF]

European Journal of Immunology, 1998
Murine medullary thymic epithelial cells (mTEC), but not cortical thymic epithelial cells (cTEC), are able to present a soluble antigen, ovalbumin, to helper T cells (Mizuochi, T. et al., J. Exp. Med. 1992. 175: 1601-1605). This functional difference between the mTEC and the cTEC is particularly important when we consider the thymic selection of the T ...

Tezepelumab in Chinese Patients With Severe Chronic Rhinosinusitis With Nasal Polyps: A Prespecified Subgroup Analysis of the Phase 3 WAYPOINT Trial

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) in Chinese patients often exhibits a mixed Type 1/2/3 inflammatory phenotype (63%), potentially impacting the efficacy of biologics targeting Type 2 inflammation. This prespecified subgroup analysis of WAYPOINT (NCT04851964) evaluated the efficacy and safety of tezepelumab in Chinese

Efficacy and Predictors of Response to Biologic Therapy and Endoscopic Sinus Surgery in Patients With Nasal Polyps: A Systematic Review

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Biologics and endoscopic sinus surgery (ESS) treat refractory chronic rhinosinusitis with nasal polyposis (CRSwNP), but direct comparisons are lacking. We synthesized efficacy and subgroup data across randomized controlled trials (RCTs) of biologics and ESS.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Age-Associated Decline in Thymic B Cell Expression of Aire and Aire-Dependent Self-Antigens

Cell Reports, 2018
Summary: Although autoimmune disorders are a significant source of morbidity and mortality in older individuals, the mechanisms governing age-associated increases in susceptibility remain incompletely understood.

Age-related thymic involution is mediated by Fas on thymic epithelial cells [PDF]

International Immunology, 2004
Age-related thymic involution, which is linked to senescence of the immune system, was found to be mediated by the death receptor Fas. The thymus of aged Fas(-/-) mice exhibited an intact structure and the normal differentiation of thymocytes. Both thymocytes and thymic epithelial cells (TECs) were sensitive to Fas-mediated apoptosis, and in vivo ...

Pharmacokinetics and safety of tezepelumab in children with mild, moderate or severe asthma and adolescents with mild‐to‐moderate asthma

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Tezepelumab is a human monoclonal antibody that blocks the activity of thymic stromal lymphopoietin and is approved for adolescents and adults with severe asthma. This analysis assessed pharmacokinetics (PK), pharmacodynamics and safety of tezepelumab up to 85 days postdose in adolescents and children.

The role of neural crest cells in the development, organisation and migration of the thymus [PDF]

, 2010
Neural Crest (NC) derived mesenchyme has previously been shown to play an important role in the early development of the foetal thymus. Using Wnt1-Cre and Sox10-Cre mice crossed to Rosa26eYfp reporter mice, NC derived mesenchymal cells were revealed in
