ABSTRACT Altered intestinal immune homeostasis leads to chronic inflammation in Crohn’s disease (CD). To address disease- and tissue-specific alterations, we performed a T cell-centric mass cytometry analysis of peripheral and intestinal lymphocytes from patients with CD and healthy donors’ PBMCs. Chronic intestinal inflammation enforced … Read more

Activation of endogenous retroelements can trigger cGAS/STING pathway and downstream pro-inflammatory cytokine production. M1 macrophages, which can be induced by pro-inflammatory cytokines, are involved in the development of colitis. Here we aimed to determine … Read more

ABSTRACT The lungs represent a dynamic microenvironment where airway macrophages (AMs) are the major lung-resident macrophages. AMs dictate the balance between tissue homeostasis and immune activation and thus have contradictory functions by maintaining tolerance and tissue homeostasis, as well as initiating strong inflammatory responses. … Read more

ABSTRACT To establish protection against harmful foreign antigens, the small intestine harbors guardian sites called Peyer’s patches (PPs). PPs take up antigens through microfold (M) cells and transfer them to the sub-epithelial dome (SED), which contains a high density of mononuclear phagocytes (MPs), for … Read more

ABSTRACT Infections by enteric virus and intestinal inflammation are recognized as a leading cause of deadly gastroenteritis, and NLRP6 and NLRP9b signaling control these infection and inflammation. However, the regulatory mechanisms of the NLRP6 and NLRP9b signaling in enteric viral infection remain unexplored. In … Read more

ABSTRACT While much is known about the functional effects of type 2 cytokines interleukin (IL)-4, IL-5 and IL-13 in homeostasis and disease, we still poorly understand the functions of IL-9. Chronic inflammation seen in allergic diseases, autoimmunity and cancer is however frequently accompanied by … Read more

ABSTRACT Epithelial barriers such as the skin, lung, and gut, in addition to having unique physiologic functions, are designed to preserve tissue homeostasis upon challenge with a variety of allergens, irritants, or pathogens. Both the innate and adaptive immune systems play a critical role … Read more

ABSTRACT Atopic diseases such as Eosinophilic Esophagitis (EoE) often progress into fibrosis (FS-EoE), compromising organ function with limited targeted treatment options. Mechanistic understanding of FS-EoE progression is confounded by the lack of preclinical models and the heavy focus of research on eosinophils themselves. We … Read more

ABSTRACT The impact of dietary fiber on intestinal T cell development is poorly understood. Here we show that a low fiber diet reduces MHC-II antigen presentation by small intestinal epithelial cells (IECs) and consequently impairs development of CD4+CD8αα+ intraepithelial lymphocytes (DP IELs) through changes … Read more
