In this paper we described the fine structure changes observed in mast cells from patients with food allergy. We studied material from 7 patients with allergy for the eggs and flour. Biopsies were obtained from the gastric mucosa, duodenum and rectum after the allergic provocation. Ultrastructural examination revealed mast cells mainly in the submucosa near the blood vessels. Mast cells had ultrastructural changes characteristic of degranulation. These facts suggest that there is correlation between mast cells and food allergen.

Mast cells, immune sentinels that respond to various stimuli in barrier organs, provide defense by expressing pattern recognition receptors, such as Toll-like receptors (TLRs). They may affect inflammatory responses and wound healing. Here, we investigated the effect of TLR2/6-stimulated mast cells on wound healing in keratinocytes.

Pulmonary nodules are the main manifestations of early lung cancer. Non-small cell lung cancer is the most common histological type of lung cancer, and the main histological classification of non-small cell lung cancer is lung adenocarcinoma. The present study aimed to analyze the differentially expressed genes between patients with benign and malignant pulmonary nodules, and to identify potential therapeutic targets for lung adenocarcinoma.

Background: Rosacea is a chronic inflammatory disease characterized by persistent erythema, papules, and pustules, mainly on the skin of the face. Rosacea is difficult to treat; therefore, identifying new treatments is crucial. Mas-related G protein-coupled receptor X2 (MRGPRX2)-mediated mast cell (MC) activation is essential in the pathogenesis of rosacea.

Tissue-resident immune cells (TRICs) are a highly heterogeneous and plastic subpopulation of immune cells that reside in lymphoid or peripheral tissues without recirculation. These cells are endowed with notably distinct capabilities, setting them apart from their circulating leukocyte counterparts. Many studies demonstrate their complex roles in both health and disease, involving the regulation of homeostasis, protection, and destruction.

Many atopic dermatitis (AD) patients have suboptimal responses to Dupilumab therapy. This study identified key genes linked to this resistance using multi-omics approaches to benefit more patients. We selected a prospective cohort of 54 CE treated with Dupilumab from the GEO database.
