To investigate the role of T cells in psoriasis, we analyzed the T-cell receptor (TCR) repertoire in peripheral blood lymphocytes (PBLs) and in skin lesions of 9 patients with chronic plaque-stage psoriasis by means of immunohistochemistry. An extended panel of monoclonal antibodies detecting 11 different V beta families was employed in this study. In the peripheral blood, no predominant TCR V beta expression was detected and interindividual differences were small. Skin-infiltrating T cells showed only marginal differences in the TCR V beta usage when compared with PBLs. However, in 3 patients the intraepidermal infiltrate comprised up to 40% of T cells expressing a TCR V beta region which was virtually absent in the peripheral blood and the dermal infiltrate. Thus, although the TCR V beta usage of skin-infiltrating T cells showed little difference compared to PBLs, several cases exhibited a significant increase of epidermotrophic T cells using one particular V beta region.

UI	MeSH Term	Description	Entries
D011565	Psoriasis	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.

D004817	Epidermis	The external, nonvascular layer of the skin. It is made up, from within outward, of five layers of EPITHELIUM: (1) basal layer (stratum basale epidermidis); (2) spinous layer (stratum spinosum epidermidis); (3) granular layer (stratum granulosum epidermidis); (4) clear layer (stratum lucidum epidermidis); and (5) horny layer (stratum corneum epidermidis).

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D016693	Receptors, Antigen, T-Cell, alpha-beta	T-cell receptors composed of CD3-associated alpha and beta polypeptide chains and expressed primarily in CD4+ or CD8+ T-cells. Unlike immunoglobulins, the alpha-beta T-cell receptors recognize antigens only when presented in association with major histocompatibility (MHC) molecules.
