TLR4group 2 innate lymphoid cells contribute to persistent type 2 immunity in airway diseases.

Group 2 innate lymphoid cells (ILC2s) directly contribute to local inflammation in type 2 inflammatory airway diseases. Here, we identify ILC2 subsets by single cell RNA sequencing in chronic rhinosinusitis with nasal polyps (CRSwNP) and in a memory inflammatory mouse model. We find that toll-like receptor 4 (TLR4)ILC2s, with similar markers to their human counterparts, expresse memory cell markers, persist over time, and respond more vigorously to a secondary unrelated antigen challenge in the mouse model.

Amphiregulin Mediates Epithelial Cell-Eosinophil Interactions and Amplifies Inflammation in Chronic Rhinosinusitis With Nasal Polyps.

Background: Eosinophils easily accumulate in the intra-epithelial layer and subepithelial regions in eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). While several factors influence the migration of eosinophils from peripheral blood to extravascular tissues, the triggers and role of eosinophils near the epithelial layer in CRSwNP remain unclear.

Methods: We examined interactions between eosinophils and epithelial cells using co-culture systems.

Role of CD44CCR2CD64monocyte-derived macrophage in chronic rhinosinusitis with nasal polyps.

Heterogeneity of monocyte-derived macrophages (MDMs) is gradually recognized in polyp tissue of chronic rhinosinusitis with nasal polyps (CRSwNP). However, the contributions of MDM subsets for sustaining inflammation remain unclear. This study therefore aimed to characterize MDM subsets in polyp tissues and estimate their functions.

Effects of Traditional Chinese Medicine "Fuzheng Qingdu Decoction" on Autonomic Function and Cancer-Related Symptoms in Patients with Advanced Gastric Cancer undergoing Chemotherapy: A Controlled Trial.

Objective: To evaluate the effects of Fuzheng Qingdu Decoction (FZQDD) on the autonomic function and cancer-related symptoms of patients with advanced gastric cancer undergoing chemotherapy to verify its clinical efficacy.

Methods: Sixty-two patients with stage III or IV gastric cancer were included in this study. The patients were divided into 2 groups: the chemotherapy (33 patients) and chemotherapy with FZQDD (29 patients) groups.

Dynamic changes of nasal tight junctions in patients with convalescent COVID-19 with allergic rhinitis.

Nasal tight junction module score correlates negatively to allergy module score in COVID-19. Omicron variant may slow-down tight junction restoration in patients with AR.

A diagnostic model for predicting type 2 nasal polyps using biomarkers in nasal secretion.

Background: Predicting type 2 chronic rhinosinusitis with nasal polyps (CRSwNP) may help for selection of appropriate surgical procedures or pharmacotherapies in advance. However, an accurate non-invasive method for diagnosis of type 2 CRSwNP is presently unavailable.

Methods: To optimize the technique for collecting nasal secretion (NasSec), 89 CRSwNP patients were tested using nasal packs made with four types of materials.

The Influence of Body Mass Index on Glucocorticoid Insensitivity in Chronic Rhinosinusitis with Nasal Polyps.

Background: Reasons for glucocorticoid (GC) insensitivity in chronic rhinosinusitis with nasal polyps (CRSwNP) are not completely clear. Here, we investigate the influence of body mass index (BMI) on GC insensitivity in eosinophilic CRSwNP (eosCRSwNP) and noneosinophilic CRSwNP (noneosCRSwNP) patients.

Methods: We recruited 699 CRSwNP patients and gave them a course of oral methylprednisolone for 2 weeks (24 mg/day).

The TCM Prescription Yi-Fei-Jie-Du-Tang Inhibit Invasive Migration and EMT of Lung Cancer Cells by Activating Autophagy.

Yi-Fei-Jie-Du-Tang (YFJDT) is a traditional Chinese medicine formulation. Our previous studies have demonstrated that YFJDT can be used to treat non-small-cell lung cancer (NSCLC), but its protective effect against NSCLC and its mechanisms remain unclear. In the present study, we evaluated the protective effects and potential mechanisms of YFJDT on a tumor-bearing mouse lung cancer model and A549 cell model.

Adeno-associated virus (AAV)-based gene therapy for glioblastoma.

Glioblastoma (GBM) is the most common and malignant Grade IV primary craniocerebral tumor caused by glial cell carcinogenesis with an extremely poor median survival of 12-18 months. The current standard treatments for GBM, including surgical resection followed by chemotherapy and radiotherapy, fail to substantially prolong survival outcomes. Adeno-associated virus (AAV)-mediated gene therapy has recently attracted considerable interest because of its relatively low cytotoxicity, poor immunogenicity, broad tissue tropism, and long-term stable transgene expression.
