摘要:
A target-specific gene delivery system is made of enzymatically degradable gelatin and nucleic acids (DNA or RNA) microparticles with a linking moiety or a targeting ligand attached to the surface. The delivery system can be made by a simple method. Targeting ligands can be attached to the microparticle directly or via a linking moiety. The linkage design allows the attachment of any molecule onto the microparticle surface including antibodies, cell adhesion molecules, hormones and other cell-specific ligands.

A gene delivery system is made of enzymatically degradable polymeric cation and nucleic acid (DNA or RNA) nanospheres optionally with a linking moiety or a targeting ligand attached to the surface. The delivery system can be made by a simple method of coacervation. Targeting ligands can be attached to the nanosphere directly or via a linking moiety. The linkage design allows the attachment of any molecule onto the nanosphere surface including antibodies, cell adhesion molecules, hormones and other cell-specific ligands.

摘要:
The invention provides chimeric proteins and nucleic acids encoding these which can be used to generate vaccines against selected antigens. In one aspect, a chimeric protein comprises an antigen sequence and a domain for trafficking the protein to an endosomal compartment, irrespective of whether the antigen is derived from a membrane or non-membrane protein. In one preferred aspect, the trafficking domain comprises a lumenal domain of a LAMP polypeptide. Alternatively, or additionally, the chimeric protein comprises a trafficking domain of an endocytic receptor (e.g., such as DEC-205 or gp200-MR6). The vaccines (DNA, RNA or protein) can be used to modulate or enhance an immune response against any kind of antigen. In one preferred aspect, the invention provides a method for treating a patient with cancer by providing a chimeric protein comprising a cancer-specific antigen or a nucleic acid encoding the protein to the patient.
摘要:
A system for wirelessly coupling a radio device (111) via a radio link has a support surface (119) for placing radio device (111) thereon; an antenna in order to produce and maintain wireless coupling of the radio device, or a plurality of antennas (217a, 217b) positioned adjacently which can be selectively operated to produce and maintain wireless coupling of radio device (111). Support surface (119) has a rotationally symmetrical recess (117) extending around an axis of rotation (18) perpendicular to support surface (119), wherein, at different rotational positions relative to the axis of rotation (18), a radio device (111) having a projection (204) which engages in recess (117) can operate a radio link to the antenna, or to one of the antennas (217). Alternatively a radio device rests against support surface (119) and is located in any orientation and any position within a space defined by support surface (7).
