Abstract: Disclosed are expressible reverse gene constructs, and oligonucleotides, which are characterized by the ability to hybridize with an Ii mRNA molecule, thereby inhibiting translation of the Ii mRNA molecule. These compositions are referred to generally as inhibitors of Ii expression. Also disclosed are MHC class II-positive antigen presenting cells containing an inhibitor of Ii expression. A particularly important class of MHC class II-positive antigen presenting cells are malignant MHC class II-positive antigen presenting cells (e.g., leukemia, lymphoma and melanoma). Also disclosed are methods which result in the display of an autodeterminant peptide, in association with an MHC class II protein, on the surface of an MHC class II-positive antigen presenting cell. In such methods, a specific inhibitor of Ii synthesis is introduced into an MHC class II-positive antigen presenting cell. The specific inhibitor functions, directly or indirectly, through the formation of a duplex molecule with mRNA encoding Ii. The formation of the duplex molecule functions to inhibit Ii synthesis at the translational level. Also disclosed are therapeutic methods for the treatment of malignancy in an MHC class IIpositive antigen presenting cell, and autodeterminant peptides which are isolated from an MHC class II-positive antigen presenting cell.

Abstract: A tensioning device for tensioning the plastic band. The device has a tensioning element which can be rotated about an axis and has a flat gripping region. A  clamping element is also mounted such that it can be rotated about the axis and, when the tensioning element is in the inoperative position, is supported against a stop. In this position, the plastic band can be moved freely between the gripping surface of the clamping element and the tensioning element. To tension the plastic band, the tensioning element is rotated in the tensioning direction and the gripping region of the tensioning element is thereby moved against the gripping surface so that the plastic band is held in a planar manner. With the plastic band being held, the gripping region, as seen in the tensioning direction and with respect to the axis, is inclined inwardly in the radial direction. During further rotation of the tensioning element the plastic band which is clamped between the tensioning element and the clamping element is tensioned.
