Abstract: The invention relates to a composition comprising a macromolecule or particle having one or several hydrophobic domains on the surface thereof whereby at least one transducer peptide is adsorbed thereon. Said composition can be used to introduce the macromolecule or particle into living cells.

Abstract: The invention concerns novel uses of peptides derived from the cytoplasmic domain of the amyloid protein precursor (APP); said peptides are in particular sequences including the membrane domain juxtaposed to the cytoplasmic domain of the amyloid protein precursor (APP) (one-letter code), selected in the group consisting of the sequences Y1KQYTSIHHGY0 (SEQ ID NO:2). Y1KKQYTSIHHGY0 (SEQ ID NO:3) and Y1KKKQYTSIHHGY0 (SEQ ID NO:4), wherein Y0 is nil or represents V, VV, VVE, VVEV or VVVED and Y1 represents an internalisation and addressing peptide, derived from the 3rd helix of homeodomains and structually related peptides. The invention also concerns the use of a peptide comprising the membrane domain juxtaposed to the cytoplasmic domain of the amyloid protein precursor (APP), for selecting and screening products capable of inhibiting apoptosis.

Abstract: The invention concerns peptide vectors, comprising a transduction domain, and a nuclear export sequence, for carrying a molecule of interest through an epithelium with tight junctions, such as the blood-brain barrier.

Abstract: Transcription factor responsive elements, target genes, and co-factors of a transcription factor, either individually or in combination, are identified by integrating into the genome of a eukaryotic cell a gene trap vector that includes a reporter gene, a polyadenylation site, and a selectable marker gene, selecting the cells in which the gene trap vector is successfully integrated and contacting those cells with the transcription factor, then identifying and cultivating those cells having a gene into which the gene trap vector has been integrated and in which the reporter gene activity has been altered by interaction between the transcription factor and a transcription factor responsive element of that gene, and identifying the transcription factor responsive element, target gene, or cofactor that interacts with the transcription factor.

Abstract: The invention relates to a peptide of sequence (I) or (Ia): ##STR1## where X.sub.1, X.sub.2, X.sub.3, X.sub.4, X.sub.5, X.sub.7, X.sub.8, X.sub.9, X.sub.10, X.sub.11, X.sub.12, X.sub.13, X.sub.14, X.sub.15, X.sub.16 each represent an .alpha.-amino acid, X.sub.6 representing tryptophan. This peptide comprises between 6 and 10 hydrophobic amino acids.The invention also relates to the use of the said peptide for introducing, into living cells, a molecule which is active on the cellular functions.

Abstract: The invention relates to a method for introducing a macromolecule comprising at least the helix 3 of a homeobox peptide into a living cell. In particular the macromolecule is active as a cell growth factor, in particular a neurotrope.
