Abstract: Methods for inducing antigen-specific T cell tolerance are disclosed. The methods involve contacting a T cell with: 1) a cell which presents antigen to the T cell, wherein a ligand on the cell interacts with a receptor on the surface of the T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor on the surface of the T cell which inhibits interaction of the ligand on the antigen presenting cell with the receptor on the T cell. In a preferred embodiment, the cell which presents antigen to the T cell is a B cell and the receptor on the surface of the T cell which mediates contact-dependent helper effector function is gp39. Preferably, the antagonist is an anti-gp39 antibody or a soluble gp39 ligand (e.g., soluble CD40). The methods of the invention can be used to induce T cell tolerance to a soluble antigen or to an allogeneic cell. The methods of the invention can also be used to induce tolerance in cases of bone marrow transplantation and other organ transplants and to inhibit graft-versus-host disease.

Title: Mechanical actuator, especially for motor vehicle brakes
Inventor: WAGNER LOTHAR
IPC: F16D65/22
Filed: 1994-09-14
Abstract: A lever (22) having a slot (28) and an abutment (30) is fitted to pivot about an axis (A) on a casing (18). In the slot (28) there is a cable (40), a thickened end-piece (42) of which bears on the abutment (30) so that the lever (22) can be pivoted by tension (C) on the cable. The lever (22) has a projection (34) which is opposite the abutment (30) in the extension of the cable (40) to form a gap (32). The end-piece (43) lies in the gap (32) and is supported to transmit the thrust (D) of the cable on the projection (34). On the side of the projection away from the abutment (30) there is a ramp (38) on which the end-piece (42) of the cable (40) in the slot can be placed and from which the end-piece (42) slips into the gap (32) when tension (C) is exerted on the cable. This facilitates the assembly of the actuator, especially in a motor vehicle.

In particular, it comprises a heat-sink element (18) which has a first largest surface to be insulated by means of a plastic material layer with a first thickness, and a second largest surface, opposite from the first, to be insulated by means of a layer of plastic material with a second thickness which is thin compared to the first thickness; and a leadframe (17) consisting of a metal strip attached to the heat-sink element (18) on the same side as the first largest surface and comprising an peripheral holder structure (7) located outboard of the heat-sink element (18). 
     Formed in a portion of a side surface (19) of the heat-sink element (18), is a relief (20) which has mouths located on the first and second largest surfaces of the heat-sink element (18), the mouth formed on the first largest surface being closed by an obstructing means (21) which extends to the heat-sink element (18) outside, toward the peripheral structure (7), such as to only leave a slit (A2) open between the obstructing means (21) and said peripheral structure (7) of the leadframe (17) next to the first largest surface of the heat-sink element and leave the mouth toward the second largest surface open wide. 
     For the purpose of this invention, the spoiler and relief are provided at a mold gate for introducing the molten plastic material during the molding process. Thus, the relief is formed in the proximity of a side corner edge of the heat sink.
