New insights of T cells in the pathogenesis of psoriasis.
Summary of "New insights of T cells in the pathogenesis of psoriasis."
Psoriasis is one of the most common immune-mediated chronic, inflammatory skin diseases characterized by hyperproliferative keratinocytes and infiltration of T cells, dendritic cells, macrophages and neutrophils. Although the pathogenesis of psoriasis is not fully understood, there is ample evidence suggesting that the dysregulation of immune cells in the skin, particularly T cells, plays a critical role in psoriasis development. In this review, we mainly focus on the pathogenic T cells and discuss how these T cells are activated and involved in the disease pathogenesis. Newly identified 'professional' IL-17-producing dermal γδ T cells and their potential role in psoriasis will also be included. Finally, we will briefly summarize the recent progress on the T cell and its related cytokine-targeted therapy for psoriasis treatment.Cellular & Molecular Immunology advance online publication, 18 June 2012; doi:10.1038/cmi.2012.15.

Medical and Biotech [MESH] Definitions
A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region. Accelerated epidermopoiesis is considered to be the fundamental pathologic feature in psoriasis.
An antiviral antibiotic produced by Cephalosporium aphidicola and other fungi. It inhibits the growth of eukaryotic cells and certain animal viruses by selectively inhibiting the cellular replication of DNA polymerase II or the viral-induced DNA polymerases. The drug may be useful for controlling excessive cell proliferation in patients with cancer, psoriasis or other dermatitis with little or no adverse effect upon non-multiplying cells.
Human immune-response, D-related antigen encoded by the D locus on chromosome 6 and found on lymphoid cells. It is strongly associated with celiac disease and psoriasis vulgaris.
Adhesins, Escherichia Coli
Thin, filamentous protein structures, including proteinaceous capsular antigens (fimbrial antigens), that mediate adhesion of E. coli to surfaces and play a role in pathogenesis. They have a high affinity for various epithelial cells.
Neuronal growth factor and lymphokine product of lectin-stimulated T-cells which induces immunoglobulin secretion. Its amino acid sequence is partially homologous to the HIV envelope glycoprotein gp120, which may explain, in part, the pathogenesis of AIDS DEMENTIA COMPLEX. Closely related to PHOSPHOHEXOSE ISOMERASE; AUTOCRINE MOTILITY FACTOR and maturation factor.
Psoriasis is an inflammatory disease with dynamic interactions between the immune system and the skin. Recent studies have demonstrated that the interleukin (IL)-23//T-helper (Th)17 cell axis plays an...
Psoriasis is a chronic skin disease mediated by Th17 and/or Th1 cells. Tim-3 is a cell surface molecule preferentially expressed on Th17 and Th1 cells. The interaction of Tim-3 with Tim-3 ligand inhib...
Psoriasis is a common, immune-mediated inflammatory skin disorder. T helper(h)1 and Th17 lymphocytes contribute to the pathogenesis of psoriasis through the release of inflammatory cytokines that prom...
PURPOSE: To evaluate circulating and lesional CD4(+) and CD8(+) cells belonging to Th1, Th2, and Th17 patterns as well as IL-10(+) cells before and after a 12-week lasting course with etanercept or ac...
Background The pathogenesis of psoriasis has not been known exactly yet. Recently, it has been suggested that increased reactive oxygen species (ROS) such as nitric oxide (NO) and malondialdehyde (...
Psoriasis vulgaris is a chronic disease in which psoriatic plaques may appear on the knees, elbows, scalp and trunk. Evidence suggests the role of neurogenic inflammation in the pathogenes...
The pathogenesis of psoriasis has evolved from epidermal hyperproliferation to immune dysregulation in recent years. A Th1 cytokine profile is universally found is psoriasis. Biologics tar...
CRx-191 is a proprietary synergistic combination drug candidate being evaluated by CombinatoRx for topical psoriasis therapy. CRx-191 was identified via a proprietary screening assay for n...
Interdigital psoriasis (psoriasis alba) is atypical and rare form of psoriasis that is often missed as it is commonly mistaken for either dermatoses or fungal infection.In this study we ob...
We are doing this research study to evaluate the effectiveness and safety of fluphenazine decanoate when injected with a needle into psoriasis lesions in adults. Fluphenazine decanoate is...
