Abstract: The invention provides CD27 agonists comprising a first component that is an anti-CD27 antibody, or antigen-binding fragment thereof, linked to a second component comprising one or more cross-linking moieties. At least one of the cross-linking moieties does not bind to an Fc receptor and the CD27 agonist stimulates T cell activity without the need for Fc receptor interaction. The cross-linking molecule(s) can be, for example, an anti-CD27, antibody, or antigen-binding fragment thereof, that can be the same or different than the first component. Alternatively, the cross-linking molecule(s) can be a CD27 ligand or a molecule (e.g., antibody) that binds a molecule on a cell such as a T cell, a tumor cell or a stromal cell. Pharmaceutical compositions comprising the CD27 agonists, and methods of using the CD27 agonists, are also provided.

Abstract: The present invention relates to the field of biomedicine, specifically to a monoclonal antibody targeting SIRP?, and a preparation method and the use thereof. The SIRP? antibody or the antigen-binding portion thereof prepared by the present invention has a high affinity for SIRP? and a low affinity for SIRP?, which differ by two orders of magnitude. The SIRP? antibody or the antigen-binding portion thereof can efficiently block the binding of CD47 to SIRP?-V1, SIRP?-V2 and SIRP?-V8, thereby promoting the activation of macrophages, particularly enhancing the regulatory antibody-dependent cellular phagocytosis (ADCP) of a target tumor cell, bridging about innate and adaptive immune responses, and promoting the synergistic anti-cancer effect of the SIRP? antibody or the antigen-binding portion thereof with a checkpoint inhibitor PD-(L)1 monoclonal antibody. The antibody can be used for treating various cancers and microbial infectious diseases.
