All-trans retinoic acid (RA) stimulates events in organ-cultured human skin that underlie repair. Adult skin from sun-protected and sun-exposed sites responds in an identical manner to RA while neonatal foreskin responds differently.

Varani, J, Perone, P, Griffiths, C E, Inman, D R, Fligiel, S E, Voorhees, J J

Adult human skin from a sun-protected site (hip) and from a sun-exposed site (forearm) was maintained in organ culture for 12 d in the presence of a serum-free, growth factor-free basal medium....

Human immunodeficiency virus (HIV) transcripts identified in HIV-related psoriasis and Kaposi's sarcoma lesions.

Mahoney, S E, Duvic, M, Nickoloff, B J, Minshall, M, Smith, L C, Griffiths, C E, ...

Persons with HIV infection sometimes develop aggressive psoriasis or Kaposi's sarcoma (KS) not usually seen in other immunosuppressed patients. However, a specific and direct pathophysiological role...

Human skin levels of retinoic acid and cytochrome P-450-derived 4-hydroxyretinoic acid after topical application of retinoic acid in vivo compared to concentrations required to stimulate retinoic acid receptor-mediated transcription in vitro.

Duell, E A, Aström, A, Griffiths, C E, Chambon, P, Voorhees, J J

Metabolism of retinoic acid to a less active metabolite, 4-hydroxyretinoic acid, occurs via cytochrome P-450 isozyme(s). Effect of a pharmacological dose of retinoic acid on the level of retinoic...

Intraepidermal but not dermal T lymphocytes are positive for a cell-cycle-associated antigen (Ki-67) in mycosis fungoides.

Nickoloff, B. J., Griffiths, C. E.

The Ki-67 antibody, which reacts with nuclei of actively proliferating cells, was used in an immunohistochemical study to determine if there was any difference between T cells located in the...

The spindle-shaped cells in cutaneous Kaposi's sarcoma. Histologic simulators include factor XIIIa dermal dendrocytes.

Nickoloff, B. J., Griffiths, C. E.

Kaposi's sarcoma is a neoplasm that develops as multifocal lesions, often involving the skin, characterized by a complex histologic picture including numerous vascular spaces, perivascular and...

Keratinocyte intercellular adhesion molecule-1 (ICAM-1) expression precedes dermal T lymphocytic infiltration in allergic contact dermatitis (Rhus dermatitis).

Griffiths, C. E., Nickoloff, B. J.

The ability of small molecules such as urushiol, present as a wax on the poison ivy leaf surface, to cause allergic contact dermatitis (rhus dermatitis) has fascinated immunologists for decades....

Different HLA associated gene combinations contribute to susceptibility for coeliac disease and dermatitis herpetiformis.

Sachs, J A, Awad, J, McCloskey, D, Navarrete, C, Festenstein, H, Elliot, E, ...

Forty two white patients of British or Irish descent with coeliac disease and 28 with dermatitis herpetiformis were typed for class I HLA-A, B, and C, and class II DR and DQ antigens. In coeliac...

Cellular localization of interleukin-8 and its inducer, tumor necrosis factor-alpha in psoriasis.

Nickoloff, B. J., Karabin, G. D., Barker, J. N., Griffiths, C. E., Sarma, V., Mitra, R. S., ...

The importance of immunologic mechanisms in psoriasis has been deduced from the ability of immunosuppressive therapies to ameliorate this common and chronic skin disease. Certainly the histology of...

Effects of all-trans retinoic acid and Ca++ on human skin in organ culture.

Varani, J., Fligiel, S. E., Schuger, L., Perone, P., Inman, D., Griffiths, C. E., ...

In this study, we have established an organ culture model of human skin and examined the effects of both all-trans retinoic acid (RA) and extracellular Ca++ on the epidermal and dermal components of...

Preferential activation of CD4 T lymphocytes in the lamina propria of gluten-sensitive enteropathy.
