BACKGROUND Psoriasis is a common immune-mediated inflammatory disease that affects the skin and joints. The interleukin (IL)-23/IL-17A axis and IL-22 play key roles in the pathogenesis of psoriasis. IL-23-responsive innate lymphoid cells (ILCs) with a high capacity to produce IL-17 and/or IL-22 have recently been identified and associated with inflammatory(More)
BACKGROUND It has been suggested that interleukin (IL)-17 and IL-22 play important roles in the elicitation of human allergic contact dermatitis; however, the frequencies of T cell subtypes producing IL-17 and IL-22 in human allergic contact dermatitis are unknown. OBJECTIVES To determine the frequencies of CD4(+) , CD8(+) and γδ T cells producing IL-17,(More)
Psoriasis is a systemic disease with cutaneous manifestations. MicroRNAs (miRNAs) are small non-coding RNA molecules that are differentially expressed in psoriatic skin; however, only few cell- and region-specific miRNAs have been identified in psoriatic lesions. We used laser capture microdissection (LCM) and next-generation sequencing (NGS) to study the(More)
The vitamin D analogue calcipotriol is an immunomodulatory drug widely used to treat psoriasis; however, how calcipotriol affects the immune cells in psoriasis lesions is not fully understood. The aim of this study was to investigate the effect of calcipotriol on the frequency of CD4(+) and CD8(+) T cells and innate lymphoid cells (ILC) and their production(More)
Substances that penetrate the skin surface can act as allergens and induce a T cell-mediated inflammatory skin disease called contact hypersensitivity (CHS). IL-17 is a key cytokine in CHS and was originally thought to be produced solely by CD4(+) T cells. However, it is now known that several cell types, including γδ T cells, can produce IL-17. In this(More)
To investigate differences in expression of surface markers, cytokine profiles, and presence of CD4+CD8+ T cells in skin-derived T cell cultures from patients with extrinsic atopic dermatitis (AD), intrinsic AD, and psoriasis expanded in the presence of IL-2 and IL-4. Skin biopsies from patients with extrinsic AD (n = 6), intrinsic AD (n = 9) and psoriasis(More)
BACKGROUND Inflammatory cytokines produced by cells of the immune system are believed to play a central role in the pathogenesis of multiple sclerosis (MS). Innate lymphoid cells (ILCs) have been shown to produce and secrete a wide range of the cytokines involved in MS pathogenesis; however, a possible implication of ILCs in MS development and disease(More)
Atopic dermatitis (AD) is a common inflammatory skin disease with underlying defects in epidermal function and immune responses. In this study, we used microarray analysis to investigate differences in gene expression in lesional skin from patients with mild extrinsic or intrinsic AD compared to skin from healthy controls and from lesional psoriasis skin.(More)
Psoriasis is a prevalent chronic inflammatory skin disease of unknown etiology. Recent advances in understanding the pathogenesis of psoriasis suggest that IL-17 is a key proinflammatory mediator present in the skin. Several agents targeting IL-17 or its receptor are in clinical trials for the treatment of psoriasis. This review focuses on the biological(More)
