Abstract: Disclosed in the present invention are a humanized antibody that can specifically bind to TNFR2, or an antigen-binding fragment thereof. The humanized antibody or antigen-binding fragment thereof can regulate the function of immune cells and can be used in a drug for treating diseases related to immune abnormalities, such as tumours.

Abstract: Provided are a human IL-15 molecule mutant and a fusion protein containing the IL-15 mutant and combined mutations, wherein the fusion protein can mediate the activation and amplification of immune cells and can be used for treating tumor disease

Abstract: An antibody or antigen-binding fragment specifically binds to human programmed cell death ligand-1 (PD-L1). The antibody or antigen-binding fragment is able to enhance the function of T cells and upregulate a T cell-mediated immune response. The antibody or the antigen-binding fragment is useful for the treatment of diseases, e.g. tumor, associated with aberrant expression of PD-L1 and/or dysfunction of T cells.

Abstract: An antibody or an antigen-binding fragment thereof capable of specifically binding to TNFR2, the antibody or the antigen-binding fragment thereof is capable of regulating the function of immune cells and may be used as a medicament to treat diseases related to immune-related disorders, such as tumors.

Abstract: Embodiments of the present disclosure provide a multi-band antenna and a terminal device. The multi-band antenna includes a feedpoint, a matching network, a capacitor assembly, a radiation portion, and a grounding portion. The feedpoint, the matching network, the capacitor assembly, the radiation portion, and the grounding portion are connected in sequence. The matching network includes at least a serially-connected inductor and a grounded capacitor or inductor. The grounding portion is electrically connected to a ground plane. A first resonant circuit is formed from the feedpoint to the grounding portion. The first resonant circuit generates a first resonance frequency and a second resonance frequency. The first resonance frequency is used in a CRLH mode, and the second resonance frequency is used in a half-wavelength loop mode.
