ceramide/potato

Aegerolysins ostreolysin A (OlyA) and pleurotolysin A (PlyA), and pleurotolysin B (PlyB) with the membrane-attack-complex/perforin domain are proteins from the mushroom genus Pleurotus. Upon binding to sphingomyelin/cholesterol-enriched membranes, OlyA and PlyA can recruit PlyB to form multimeric

A new study was carried out to bring more information on the effect of the potato proteins ferment. Basal keratinocytes obtained from freshly excised skin samples of two groups of five donors, a young one (25-36-year-old) and an aged one (59-70-year-old) were established in culture. The results

Glycosphingolipid recognition by two isolectins from Solanum tuberosum was compared by the chromatogram binding assay. One lectin (PL-I) was isolated from potato tubers by affinity chromatography, and identified by MALDI-TOF mass spectrometry as a homodimer with a subunit molecular mass of 63,000.

Ceramides and glucocerebrosides of potatoes (Solanum tuberosum L.) and sweet potatoes (Ipomoea batatas (L.) Lam.) were analyzed using RP-HPLC-ESI-MS/MS. Ceramides and glucocerebrosides containing the three different long-chain bases 4,8-sphingadienine (d18:2(delta4,delta8)), 4-hydroxy-8-sphingenine

Mycochemical examination of a methanol extract of Scleroderma bovista Fr. (Agaricomycetes) led to the isolation of 7 compounds, which were, to our knowledge, identified for the first time in this species. The chemical structures of these compounds were determined through extensive spectroscopic

We compared the effects of maize and potato starch on Wistar rats. The level of oligonucleosomal DNA fragmentation increased in thymic and splenic cells of animals receiving potato starch. The expression of Fas/CD95/Apo-1 apoptosis receptor in lymphocytes and their response to exogenous ceramide was

Several products are known to inhibit the biosynthesis of ceramides and glucosylceramides, but very few stimulate this process. We studied the influence of a hydrolysate of potato proteins (Lipidessence) in vitro on the sphingolipid metabolism of normal human epidermal keratinocytes. By measuring

The aegerolysin proteins ostreolysin A6, pleurotolysin A2 and erylysin A are produced by mushrooms of the genus Pleurotus. These aegerolysins can interact specifically with sphingolipid-enriched membranes. In particular, they strongly bind insect cells and to artificial lipid membranes that contain
