Abstract: Provided is a bispecific antibody, comprising a first antigen-binding moiety and a second antigen-binding moiety, wherein a paired domain of the first antigen-binding moiety comprises an amino acid sequence of engineered HLA-I ?3 and an amino acid sequence of engineered ?2M. Also provided are an expression method for the bispecific antibody, a polynucleotide encoding the bispecific antibody, a vector and host cell containing the polynucleotide, a pharmaceutical composition containing the bispecific antibody, a fusion protein, and a conjugate.

Abstract: This application provides a folding assembly and a foldable electronic device. The folding assembly is applied to a foldable electronic device, and is configured to carry a flexible display screen. The folding assembly includes a shaft base, a first housing, and a second housing. The first housing and the second housing are respectively disposed on both sides of the shaft base. A door plate swing arm is located above the shaft base and is disposed on each of both sides of a center line of the shaft base, one end of each door plate swing arm is rotatably connected to the shaft base, and the other end of each door plate swing arm is rotatably connected to the first housing or the second housing.
