Speculations around the mechanism behind the action of peptide T in the healing of psoriasis: a minireview.
Johansson O, Hilliges M, Talme T, Marcusson JA, Wetterberg L.
Peptide T, the HIV envelope-derived fragment Ala-Ser-Thr-Thr-Thr-Asn-Tyr-Thr, has already been used to successfully treat psoriatic patients without major side-effects. The underlying reason for the positive effect is, however, at present unknown. In the following minireview, we summarize today's knowledge regarding peptide T's interaction with other chemical messenger molecules, such as somatosta ...

The influence of water, glycerin, paraffin oil and ethanol on skin mechanics
Overgaard Olsen L, Jemec GB
Moisturizers and emollients do not only smooth the skin but also make it more supple. To clarify this effect, the short-term influence of tap water, paraffin oil, ethanol and glycerin on skin mechanics was studied. These substances are all common ingredients in moisturizers and emollients. Significant changes were seen already after 10 min of application. The distensibility and hysteresis (creep p ...

Sphingosines: antimicrobial barriers of the skin.
Bibel DJ, Aly R, Shah S, Shinefield HR.
Among the factors that control the survival of microorganisms on human stratum corneum are skin lipids, including sphingosines. Because the antibacterial spectrum of sphinganine resembles that of cell wall antibiotics, electron microscopy of sphinganine-treated and untreated S. aureus was performed; the lipid induced multiple lesions of cell wall, membrane evaginations and loss of ribosomes. Howev ...

GM1-gangliosidosis type 1 involving the cutaneous vascular endothelial cells in a black infant with multiple ectopic Mongolian spots.
Tang TT, Esterly NB, Lubinsky MS, Oechler HW, Harb JM, Franciosi RA.
GM1-gangliosidosis (GM1) is one of the metabolic storage diseases, of which a differential diagnosis requires an array of biochemical assays to determine the enzyme deficiency. This approach is not only time-consuming and costly but also unavailable to most hospital laboratories. However, a presumptive diagnosis of GM1 may be made on the basis of coarse facial feature, foamy endothelial cells in t ...

Altered expression of beta-2-microglobulin in basaloid proliferations overlying dermatofibromas.
Rossen K, Hou-Jensen K, Werdelin O.
The epidermis overlying 2-8% of dermatofibromas shows basaloid proliferations that are indistinguishable from superficial basal cell carcinoma. It is well established that basal cell carcinomas uniformly exhibit a strongly reduced expression of HLA class I molecules. Nineteen dermatofibromas with overlying basaloid proliferations were studied by immunohistochemistry using a monoclonal antibody aga ...

Chloroquine phosphate: a long-term follow-up of drug concentrations in skin suction blister fluid and plasma.
Sjölin-Forsberg G1, Berne B, Blixt C, Johansson M, Lindström B.
Chloroquine is known to bind strongly to melanin and is accumulated in the skin. In dermatology, the drug is mainly used to treat photosensitivity disorders, but it has also been reported to cause sun sensitivity, especially in patients with rheumatoid arthritis. In the present study the concentrations of chloroquine phosphate in plasma and skin suction blister fluid (interstitial fluid in the ski ...

Adenovirus 12 and dermatitis herpetiformis.
Handley J, O'Neill H, Connolly J, Burrows D.
Previous studies have shown that A-gliadin, a major gluten-derived peptide known to activate the gluten-sensitive enteropathy (GSE) of coeliac disease (CD), and the non-structural E1B peptide produced during early lytic gastrointestinal infection with human adenovirus type 12 (AD12) share an identical twelve amino acid sequence. It is suggested that immunological cross reactivity between these two ...
