BackgroundAllergic diseases have become one of the major public health problems to be addressed in the world today. As a tissue resident cell, mast cells are crucial in the pathogenesis of allergic diseases. Vitamin A is an important fat-soluble vitamin with immunomodulatory functions.

Immune infiltration plays a significant role in the pathogenesis of rheumatoid arthritis (RA). Cuproptosis, a newly characterized form of programmed cell death, remains insufficiently investigated regarding its genetic regulation of immune infiltration in RA. Data from the GEO database were analyzed to determine the relationship between cuproptosis-related genes and immune infiltration.

Mast cells (MCs) are heterogeneous tissue-resident effector cells thought to play central roles in allergic inflammatory disease, yet the degree of heterogeneity and nature of these roles has remained elusive. In recent years, advances in tissue culture systems, pre-clinical mouse models, and the continued spread of single-cell RNA sequencing has greatly advanced our understanding of MC phenotypes in health and disease. These approaches have identified novel interactions of MC subsets with immune cells, neurons, and tissue structural cells, changing our understanding of how MCs both drive and help resolve tissue inflammation, reshape tissue microenvironments, and influence host behavior.

Background: The blood FGF21 expression has been previously suggested to increase in patients developing atopic dermatitis (AD) and asthma. However, its impact on atopic march is rarely analyzed. The present work focused on investigating the role of Fibroblast Growth Factor 21(FGF21) in atopic march mice and its underlying mechanisms.

A transcriptomic analysis of the interplay of ferroptosis and immune filtration in endometriosis and identification of novel therapeutic targets.

Endometriosis is an inflammatory disease, involving immune cell infiltration and production of inflammatory mediators. Ferroptosis has recently been recognized as a mode of controlled cell death and the iron overload and peroxidative environment prevailing in the ectopic endometrium facilitates the occurrence of ferroptosis. In the current investigation, gene expression data was obtained from the dataset GSE7305.
