APO2L/TRAIL (TNF-related apoptosis-inducing ligand) induces death of tumor cells through two agonist receptors, TRAIL-R1 and TRAIL-R2. We demonstrate here that N-linked glycosylation (N-glyc) plays also an important regulatory role for TRAIL-R1-mediated and mouse TRAIL receptor (mTRAIL-R)-mediated apoptosis, but not for TRAIL-R2, which is devoid of… (More)
Carbon nanotubes (CNT) are currently used as a promising family of nanovectors able to deliver different types of therapeutic molecules. Several applications dealing with CNT used as drug nanocarriers have been developed since their ability to penetrate into the cells has been proved. CNT can thus load several active molecules to various cells. In this… (More)
Amphotericin B (AmB) is a well-known polyene which self-organizes into membrane cell in order to cause the cell death. Its specific action towards fungal cell is not fully understood but was proved to become from sterol composition. The mechanism was shown experimentally to require the formation of stable sterol/polyene couples which could then organize in… (More)
Fundamental understanding of ionic transport at the nanoscale is essential for developing biosensors based on nanopore technology and new generation high-performance nanofiltration membranes for separation and purification applications. We study here ionic transport through single putatively neutral hydrophobic nanopores with high aspect ratio (of length L… (More)
Hydrogen and halogen bonds have been associated for the growth of 2D compact supramolecular networks on a silicon surface. These interactions have been elucidated in a complete monolayer of a 4,4''-dibromo-p-terphenyl (DBT) molecule on a Si(111)-B surface by combining scanning tunneling microscopy (STM) and density functional theory (DFT) calculations.
