Disclosed herein are also compositions and methods of use thereof for decreasing or inhibiting cytokine production in a subject experiencing cytokine release syndrome or cytokine storm including administration of a composition including apoptotic cells or an apoptotic cell supernatant.

Described herein are donor vectors and systems for use in in vivo dual recombinase-mediated cassette exchange. Also described are animal models for consistent, rigorous, and facile investigation of transgene expression. Further described are methods of screening for therapeutic drugs using these animal models, and methods of treatment.

Provided is a bispecific recombinant protein, comprising a high affinity tumor-targeting arm and a low affinity fusion protein blocking the interaction of CD47 with SIRPα. The antibody corresponding to the high affinity tumor-targeting arm does not bind to CD47, and its binding affinity to the target antigen on the tumor cell is at least 6 times as great as the binding affinity of monomer fusion protein homodimer, corresponding to the low affinity fusion protein blocking the interaction of CD47 with SIRPα, to a CD47 on the tumor cell, wherein the low affinity fusion protein blocking the interaction of CD47 with SIRPα comprises a SIRPα extracellular truncation. Also provided are nucleic acid molecules encoding recombinant proteins and the use of the recombinant proteins and nucleic acid molecules in the manufacture of a medicament for treating tumors.
