Th17, Th22 and Treg cells are enriched in the healthy human cecum

ABSTRACT: Dysregulation of CD4+ T cell populations leads to intestinal inflammation, but the regional differences of these T cell populations remained unclear in the healthy population. We first used flow cytometry to show that Th17 and Th22 cells are specifically enriched in the human cecum, while Th1 and Th2 cells do not differ regionally. We subsequently performed transcriptional profiling and found that Th17 was positively associated with the expression of RETN and negatively associated with TFF1, suggesting that the differential enrichment of Th17 cells in the healthy human cecum was underlined by the metabolic differences in this environment.

Comparative transcriptome analysis of Th22 and Th17 cells

Project description:Microarray was used to delineate the global gene expression profile underlying the specific developmental program of two divergent antigen-specific T helper subsets (Th22 versus Th17) by identifying upregulation or downregulation of key lineage-determining transcription factors, cytokines, chemokines and other genes that govern their functional attributes. To identify factors that might distinguish the Th22 and Th17 developmental programs, comparative global transcriptome analysis between these 2 subsets was performed. Naïve splenic CD4+ T cells from OT-II-transgenic mice were isolated and grown in vitro under T-helper lineage-specific conditions in the presence of cognate antigen (ovalbumin) to identify their distinctive global gene-regulation profiles.

Th22 cells represent a distinct human T cell subset involved in epidermal immunity and remodeling

Project description:Th subsets are defined according to their production of lineage-indicating cytokines and functions. In this study, we have identified a subset of human Th cells that infiltrates the epidermis in individuals with inflammatory skin disorders and is characterized by the secretion of IL-22 and TNF-a, but not IFN-g, IL-4, or IL-17. In analogy to the Th17 subset, cells with this cytokine profile have been named the Th22 subset. Th22 clones derived from patients with psoriasis were stable in culture and exhibited a transcriptome profile clearly separate from those of Th1, Th2, and Th17 cells; it included genes encoding proteins involved in tissue remodeling, such as FGFs, and chemokines involved in angiogenesis and fibrosis. Primary human keratinocytes exposed to Th22 supernatants expressed a transcriptome response profile that included genes involved in innate immune pathways and the induction and modulation of adaptive immunity. These proinflammatory Th22 responses were synergistically dependent on IL-22 and TNF-a. Furthermore, Th22 supernatants enhanced wound healing in an in vitro injury model, which was exclusively dependent on IL-22. In conclusion, the human Th22 subset may represent a separate T cell subset with a distinct identity with respect to gene expression and function, present within the epidermal layer in inflammatory skin diseases. Future strategies directed against the Th22 subset may be of value in chronic inflammatory skin disorders.

RNA sequencing keloid transcriptome associates keloids with Th2, Th1, Th17/Th22 and JAK3-skewing

Project description:In this study, we aimed to elucidate the profile of lesional and non-lesional keloid skin compared to normal skin. We performed gene (RNAseq, qRT-PCR) and protein (immunohistochemistry) expression analyses on biopsy specimens obtained from lesional and non-lesional skin of African American (AA) keloid patients compared to healthy skin from AA controls. We found that lesional versus normal skin showed significant up-regulation of markers of T-cell activation/migration (ICOS, CCR7), Th2- (IL-4R, CCL11, TNFSF4/OX40L), Th1- (CXCL9/CXCL10/CXCL11), Th17/Th22- (CCL20, S100As) pathways, and JAK/STAT-signaling (JAK3) (false-discovery rate [FDR]<0.05).

Dust mite potently activates Th17/Th22 pathways and models multiple inflammatory skin conditions in humans

Project description:House dust mite/HDM atopy patch test/APT elicits positive reactions in the majority of atopic dermatitis/AD and healthy individuals. Experimental systems for new-onset/chronic AD are needed to support rapid therapeutic development, particularly since animal models representing AD pathology in humans are lacking. HDM APT historically simulated AD, but its suitability to model the emerging AD skin phenotype as Th2/Th22 polarized with Th1 and Th17 components is unknown. To assess whether HDM APT tissues reproduce acute or chronic AD, positive HDM APT (n=14) were compared with nonlesional, acute (<72hrs; n=10), and chronic phase AD biopsies (n=8), allergic contact reactions (to nickel [n=10] and fragrance [n=3]) using arrays.
