The patent application (Publication Number: US20240034794A1) describes a method for inhibiting biological activity in cells mediated by the binding of specific membrane proteins. The method involves providing a system with an antibody that can bind to these membrane proteins, blocking their interaction and inhibiting the biological activity. The antibody used in the method can reduce inhibitory activity and enhance T cell activation potential, leading to a stronger anti-tumor response. The method targets specific membrane proteins such as PD-1 and PD-L1, known for their role in regulating immune responses.

Furthermore, the patent application details the specific characteristics of the antibody used in the method, including the amino acid sequences of the variable domains that bind to PD-1 and PD-L1. The antibody's ability to enhance T cell proliferation and induce a stronger anti-tumor response in vivo is highlighted. The method involves utilizing a bispecific antibody format with high binding affinity for the target membrane proteins. Overall, the method described in the patent application aims to modulate immune responses by targeting the interaction between specific membrane proteins, potentially leading to improved therapeutic outcomes in conditions where immune regulation is crucial, such as cancer.
