Curcumin is the main constituent of the spice turmeric, used in diet and in traditional medicine, particularly across the Indian subcontinent. Anti-inflammatory activity and inhibition of LPS signaling are some of its many activities. We show that curcumin binds at submicromolar affinity to the myeloid differentiation protein 2 (MD-2), which is the(More)
LPS is the primary ligand of Toll-like receptor 4, activating it through binding to its accessory protein MD-2. Murine but not human cells expressing MD-2/TLR4 are also activated by paclitaxel. Paclitaxel binds to human MD-2. The binding site of paclitaxel overlaps with the binding site of bis-ANS and LPS, which results in the ability of taxanes to inhibit(More)
A combination of antimicrobial and endotoxin-neutralizing activities is desired in order to prevent progression from infection to sepsis due to the release of lipopolysaccharide from dying gram-negative bacteria. Lipopolyamines have emerged as a new type of endotoxin-neutralizing compound, but their antimicrobial activity has not been investigated. We(More)
In this study, we compared three different methods used for quantification of gene electrotransfer efficiency: fluorescence microscopy, flow cytometry and spectrofluorometry. We used CHO and B16 cells in a suspension and plasmid coding for GFP. The aim of this study was to compare and analyse the results obtained by fluorescence microscopy, flow cytometry(More)
MD-2, an LPS-binding protein is essential for the recognition of LPS by TLR4. MD-2 belongs to the ML superfamily of lipid-binding proteins. The tertiary structure of mite allergen protein Der p 2 was identified as having the protein fold most compatible with the sequence of MD-2. Comparison of MD-2 and Der p 2 reveals that they have many common biochemical(More)
