Integrated single-cell transcriptomic and BCR analyses reveal how antibody class switching influences human B cell fate function.
BackgroundChronic rhinosinusitis with nasal polyposis (CRSwNP) in Western countries is characterized by eosinophilia, IgE production, and TH2 cytokine expression. Type 2 innate lymphoid cells from polyps produce IL-5 IL-13 response to IL-25 IL-33, although the relevance of this axis local mucosal T-cell responses unknown.ObjectiveWe sought investigate role IL-25/IL-33 patients CRSwNP.MethodsPolyp tissue blood were obtained undergoing polypectomy. Control biopsy specimens healthy volunteers....
The germinal center (GC) response is critical for both effective adaptive immunity and establishing peripheral tolerance by limiting autoreactive B cells. Dysfunction in these processes can lead to defective immune responses infection or contribute autoimmune disease. To understand the gene regulatory principles underlying GC response, we generated a single-cell transcriptomic epigenomic atlas of human tonsil, widely studied representative lymphoid tissue. We characterize diverse cell...
Rationale: Increases in airway smooth muscle, extracellular matrix, and vascularity are prominent features of remodeling asthma, whereas the extent such patients with persistent allergic rhinitis (PAR) is unknown.Objectives: To test hypothesis that upper a feature PAR.Methods: Total nasal symptoms scores, biopsies, Th1 Th2 cytokines from lavage were assessed subjects severe PAR (n = 46) healthy control 19). Angiolymphangiogenesis was examined using immunohistochemistry staining against CD31...
Local tissue eosinophilia and Th2 cytokines are characteristic features of seasonal allergic rhinitis. Airway remodelling is a feature asthma whereas evidence for in rhinitis (AR) conflicting.By use novel human repetitive nasal allergen challenge (RAC) model, we evaluated the relationship between inflammation AR.Twelve patients with moderate-severe AR underwent 5 alternate day challenges diluent which after 4 weeks were followed by grass pollen extract. Nasal symptoms, Th1/Th2 secretion...

Abstract In response to antigen challenge, B cells clonally expand, undergo selection and differentiate produce mature cell subsets high affinity antibodies. However, the interplay between dynamic states their antibody-based is challenging decipher in primary human tissue. We have applied an integrated analysis of bulk single-cell antibody repertoires paired with transcriptomics undergoing maturation. define unique gene expression known novel states, including a pre-germinal centre state...

Discovery of insulin in 1921 changed the lives patients with type 1 diabetes (T1DM) forever. What had been a death sentence became manageable, albeit chronic, disease. Insulin did not cure disease, as it address actual disease process, but instead treated its sequelae, namely elevated blood sugars. Importantly, administration fails to ensure normoglycaemia. Even most sophisticated ‘near closed-loop’ methods, glucose homeostasis is restored normal. T1DM face complications, both short-term,...
We describe the importance of collaboration between multiple surgical specialties in managing a complex case sight-threatening severe proptosis young woman with type 2 neurofibromatosis (NF2) complicated by pre-existing contralateral blindness. Trans-nasal and lateral orbital approaches were aided stereotactic navigation to debulk large frontal/sphenoid wing meningioma, which had been exerting pressure onto right globe optic nerve. The patient made an excellent postoperative recovery along...

A 14-month-old girl initially presented to the Accident and Emergency (A&E) department following a choking episode subsequent vomiting. The child left before being seen but re-presented morning with stridor, drooling, increased work of breathing. chest lateral neck soft tissue X-ray performed in A&E revealed an ingested button battery oesophagus. oesophagoscopy was 22 mm removed from oesophagus at level cricopharyngeus muscle, no immediate complications. Following extubation, patient...
