Cyclosporine in psoriasis treatment. Inhibition of keratinocyte cell-cycle progression in G1 independent of effects on transforming growth factor alpha/epidermal growth factor receptor pathways.
The major histocompatibility complex haplotype (supratype), HLA-A2-Cw11-Bw46-C2C-BFS-C4A4-C4B2-DRw8 is purported to be a new high-risk haplotype in Japanese patients with psoriasis.

Although previous attempts to demonstrate viral sequences in psoriasis and KS lesions have been unsuccessful, in situ hybridization with confocal microscopy has shown the presence of HIV RNA transcripts predominantly within CD4+, Factor XIIIa positive dermal dendrocytes.
Molecular cloning and expression of a novel keratinocyte protein (psoriasis-associated fatty acid-binding protein [PA-FABP]) that is highly up-regulated in psoriatic skin and that shares similarity to fatty acid-binding proteins.
Precocious expression of TGase K protein occurs in psoriasis, and quantitative Northern blot analysis of TGase K mRNA from normal and involved epidermal biopsies from psoriasis patients suggests that TGase K mRNA levels are increased in psoriatic lesions.
These results indicate a switch to the overexpression of CRABP-II mRNA in psoriasis which induces high levels of the protein mainly in LPS; these observations may be relevant to the pathophysiology and therapy of psoriasis as CRABP-I and -II have different ligand-binding affinities.
Our finding suggests that this activity of the tat gene may be responsible for the epidermal hyperplasia that accompanies psoriasis and precedes the development of squamous cell and basal cell carcinomas in AIDS patients.

To better understand the cellular target(s) of cyclosporin action in psoriasis, we have studied the effects of systemic short-term (7 d), low-dose (3-7.5 mg/kg) cyclosporin A administration on the expression of the cytokines interleukin (IL)-8 and IL-1 beta in psoriatic lesions.
The purpose of this study was to investigate and to compare, by in situ hybridization, gene expression of IL-1 beta, IL-8, TGF-beta 1, TGF-beta 2, TGF-beta 3, TGF-alpha, p53 and c-myc in lesions and in non-involved skin of patients with psoriasis.
