Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the nasal cavity characterized by excessive nasal mucus secretion and nasal congestion. The development of CRS is related to pathological mechanisms induced by hypoxia. Under hypoxic conditions, the stable expression of both Hypoxia inducible factor‐1 (HIF‐1) α and HIF‐2α are involved in the immune response and inflammatory pathways...
Humans inhale, ingest, and touch thousands of fungi each day. The ubiquity and diversity of the fungal kingdom, reflected by its complex taxonomy, are in sharp contrast with our scarce knowledge about its distribution, pathogenic effects, and effective interventions at the environmental and individual levels. Here, we present an overview of salient features of fungi as permanent players of the human...
Background
Antibody‐based tests are available for measuring SARS‐CoV‐2‐specific immune responses but fast T‐cell assays remain scarce. Robust T cell‐based tests are needed to differentiate specific cellular immune responses after infection from those after vaccination.
Methods
One hundred seventeen individuals (COVID‐19 convalescent patients: n = 40; SARS‐CoV‐2 vaccinees: n = 41; healthy controls:...
Background
The SCF/KIT axis regulates nearly all aspects of mast cell (MC) biology. A comprehensive view of SCF‐triggered phosphorylation dynamics is lacking. The relationship between signaling modules and SCF‐supported functions likewise remains ill‐defined.
Methods
Mast cells were isolated from human skin; upon stimulation by SCF, global phosphoproteomic changes were analyzed by LC–MS/MS and...
Microbial metabolism of specific dietary components, such as fiber, contributes to the sophisticated inter‐kingdom dialogue in the gut that maintains a stable environment with important beneficial physiological, metabolic, and immunological effects on the host. Historical changes in fiber intake may be contributing to the increase of allergic and hypersensitivity disorders as fiber‐derived metabolites...
Autoimmune diseases have a prevalence of approximately 7 to 9% and are classified as either organ‐specific diseases, including type I diabetes, multiple sclerosis, inflammatory bowel disease and myasthenia gravis, or systemic diseases, including systemic lupus erythematosus, rheumatoid arthritis and Sjögren's syndrome. While many advancements have been made in understanding of the mechanisms of autoimmune...
Antibiotic use during pregnancy may increase the risk for asthma in children. We performed a meta‐analysis assessing prenatal antibiotic exposure and the risk for childhood wheeze or asthma, as well as for diseases associated with the atopic march. A systematic literature search protocol (PROSPERO‐ID: CRD42020191940) was registered and searches were completed using Medline, Proquest, Embase, and the...
The inflammation of allergic diseases is characterized by a complex interaction between type 2 and type 3 immune responses, explaining clinical symptoms and histopathological patterns. Airborne stimuli activate the mucosal epithelium to release a number of molecules impacting the activity of resident immune and environmental cells. Signals from the mucosal barrier, regulatory cells, and the inflamed...
Background
Atopic dermatitis (AD) is characterized by abnormal skin lipids that are largely driven by hyperactivated type 2 immune responses. The antibody to the α‐subunit of interleukin (IL)‐4 receptor, dupilumab, was recently approved to treat AD and demonstrated strong efficacy. However, the role of dupilumab therapy in the regulation of skin barrier structure and function has not been fully explored...
