Abstract

The invention identifies PD-1 as a receptor for B7-4. B7-4 can inhibit immune cell activation upon binding to an inhibitory receptor on an immune cell. Accordingly, the invention provides agents for modulating PD-1, B7-4, and the interaction between B7-4 and PD-1 in order to modulate a costimulatory or an inhibitory signal in a immune cell resulting in modulation of the immune response.

Claims

1. A method for upmodulating an immune response comprising contacting an immune cell expressing PD-1 with an agent that downmodulates signaling via PD-1, wherein the agent comprises a non-activating form of B7-4 of SEQ ID NO:

2 or SEQ ID NO;

4, or extracellular or variable region-like domains thereof, to thereby upmodulate the immune response.

2. The method of claim 1, wherein the immune cell expressing PD-1 is selected from the group consisting of:

a T cell, a B cell, a myeloid cell, and combinations thereof.

3. The method of claim 1, further comprising contacting the immune cell with an additional agent that upmodulates an immune response wherein the additional agent is a non-activating PD-1 antibody.

4. The method of claim 1, wherein the step of contacting occurs in vivo.

5. The method of claim 1, wherein the step of contacting occurs in vitro.

6. The method of claim 1, wherein the immune cell expressing PD-1 is selected from the group consisting of:

a monocyte, a dendritic cell, a keratinocyte, a B cell, and combinations thereof

7. The method of claim 1, wherein the non-activating form of B7-4 of SEQ ID NO:

2 or SEQ ID NO;

4, or extracellular or variable region-like domains thereof, further comprises heterologous amino acid sequences.
