摘要：
SIRPabodies comprise an immunoglobulin variable region, which may specifically bind a tumor antigen, viral antigen, etc., fused to a sequence comprising a binding domain of SIRPα. The binding domain of SIRPα comprises at least the N-terminal Ig-like domain of SIRPα, and may further comprise additional SIRPα sequences. The SIRPabodies find use in therapeutic methods that benefit from the combined activity of blocking CD47 activity, and antibody targeting, e.g. in the treatment of cancer, etc. In some specific embodiments, the SIRPabody comprises anti-CD20 activity and a SIRPα binding domain； anti-CD99 and a SIRPα binding domain； or anti-TIM3 activity and a SIRPα binding domain.
