    • Provided are monoclonal antibodies and antigen-binding fragments thereof that bind to CD47 of multiple mammalian species, block the binding of SIRPalpha and TSP1 to CD47, promote phagocytosis of susceptible cancer cells, and reverse TSP1 inhibition of nitric oxide signaling, as well as monoclonal antibodies and antigen binding fragments thereof that compete with the former for binding to CD47 and that exhibit similar biological activities. Also provided are combinations of any of the foregoing. Such antibody compounds are variously effective in 1) treating tissue ischemia and ischemia-reperfusion injury (IRI) in the setting of organ preservation and transplantation, pulmonary hypertension, sickle cell disease, myocardial infarction, stroke, and other instances of surgery and/or trauma in which IRI is a component of pathogenesis; 2) in treating autoimmune and inflammatory diseases; and 3) as anti-cancer agents for treating susceptible cancer cells, promoting their phagocytic uptake and clearance.
    • 提供了结合多种哺乳动物物种的CD47的单克隆抗体及其抗原结合片段,阻断SIRPalpha和TSP1与CD47的结合,促进易感癌细胞的吞噬,并逆转一氧化氮信号传导的TSP1抑制,以及单克隆抗体 与抗原结合片段与前者竞争结合CD47并表现出类似的生物活性。 还提供了上述任何一种的组合。 这种抗体化合物在1)在器官保存和移植,肺动脉高压,镰状细胞病,心肌梗塞,中风和其他手术和/或创伤实例的设置中治疗组织缺血和缺血再灌注损伤(IRI)是各种有效的 其中IRI是发病机制的组成部分; 2)治疗自身免疫性疾病和炎性疾病; 和3)作为用于治疗敏感性癌细胞的抗癌剂,促进其吞噬摄取和清除。
