Abstract: T-cell responses are initiated via contact with MHC/peptide complexes on antigen presenting cells (APCs). The fate of these complexes, however, is unknown. Here, using live APCs expressing MHC class I molecules fused with green-fluorescent protein, we show that peptide-specific T-cell/APC interaction induces clusters of MHC I molecules to congregate within minutes at the contact site; thereafter, these MHC I clusters are acquired by T-cells in small aggregates.,We further demonstrate that acquisition of MHC I by T-cells correlates with TCR down regulation and the APC-derived MHC I molecules are endocytosed and degraded by-T-cells. These data suggest a novel mechanism by which TCR recognition of MHC/peptide complexes can be curtailed by internalization of MHC molecules by T-cells.

Title: Equipment for easing the passage of wheelchair users through differences in level, in particular over door thresholds
Inventor: FREDERIKSEN OLE
IPC: E06B1/70
Filed: 2000-07-03
Abstract: For facilitating the passage of wheelchair users over door thresholds it is known to lay out ramp elements across the threshold, this however being an expensive solution even implying that the door cannot be closed. The invention provides for a ramp set suited to be laid out at both sides of the threshold so as to leave the top side thereof uncovered, whereby the door can still be opened and closed. The ramp construction is modular based on the use of light, joinable plastic tile elements of ordinary shape and wedge shape, respectively, and this makes it possible to build up non-costly, tailored ramp constructions in more general, with an associated possibility of reusing the tile elements.

Title: Lentiviral triplex dna, and vectors and recombinant cells containing lentiviral triplex dna
Inventor: CHARNEAU PIERRE
IPC: C12N15/09
Filed: 2000-10-10
Abstract: The present invention provides nucleic acid, vectors, viruses, and recombinant cells comprising triple-stranded structures, such as those resulting from central initiation and termination of HIV-1 reverse transcription at the center of HIV-1 linear DNA genomes. These triplex structures can act as a cis-determinant of HIV-1 DNA nuclear import, allowing infection of non-dividing target cells. In one aspect, the presence of the DNA triplex sequence in an HIV vector strongly stimulates gene transfer in hematopoietic stem cells. The invention also provides methods of using these triplex structures for making recombinant cells, as well as methods of using the recombinant cells to express proteins of interest both  in vitro  and  in vivo.

Patent PT-1223598-E (PT)
Inventor: OBERNDORFER JOHANNES
IPC: H01H50/54
Filed: 2002-01-09
Abstract: The system has at least two closure elements, further contact and actuator arrangement. Each closure element has its own actuator driven by a relay armature, the movable part of each closure element is positively coupled to the associated actuator in the contact opening direction and both actuators are positively coupled to the movable part of the further contact only in the direction towards the operating position. The system has at least two closure elements (10,20), a further contact (30) and an actuator arrangement with at least two parallel movable components that closes both closure elements and the further contact by moving a relay armature into its operating position and opens both closure elements by returning the armature to its rest position, but prevents restoration of the further contact if one closure element does not open. Each closure element has its own actuator (40,50) driven by the relay armature, the movable part of each closure element is positively coupled to the associated actuator in the contact opening direction and both actuators are positively coupled to the movable part (35) of the further contact only in the direction towards the operating position.
