Engineering TME-activated CD47-specific CAR macrophage via Arg1 promoter for safe and effective solid tumor immunotherapy [PDF]
Background Chimeric antigen receptor macrophage (CAR-Mφ) therapy has promising therapeutic potential in solid tumors, yet challenges remain in target compatibility and systemic toxicity.Methods In this study, we screened the CD47-scFv sequence of CAR-Mφ ...

Harnessing the innate immune system: a novel bispecific antibody targeting CD47 and CD24 for selective tumor clearance [PDF]
Background Tumor-associated macrophages (TAMs) abundantly infiltrate tumors and possess potent antitumor capabilities. “Don‘t eat me” signals like CD47 allow tumors to evade macrophages and proliferate unchecked.

CD47 expression is critical for CAR T-cell survival in vivo
Background CD47 is an attractive immunotherapeutic target because it is highly expressed on multiple solid tumors. However, CD47 is also expressed on T cells.

Engineered CAR-T cells targeting TAG-72 and CD47 in ovarian cancer
Chimeric antigen receptor (CAR) T cells have revolutionized blood cancer immunotherapy; however, their efficacy against solid tumors has been limited. A common mechanism of tumor escape from single target therapies is downregulation or mutational loss of

Loss of CD47 alters CD8+ T cell activation in vitro and immunodynamics in mice
CD47 has established roles in the immune system for regulating macrophage phagocytosis and lymphocyte activation, with growing evidence of its cell-intrinsic regulatory roles in natural killer and CD8+ T cells.

CD47 Enhances In Vivo Functionality of Artificial Antigen-Presenting Cells [PDF]
Abstract Purpose: Artificial antigen-presenting cells, aAPC, have successfully been used to stimulate antigen-specific T-cell responses in vitro as well as in vivo. Although aAPC compare favorably with autologous dendritic cells in vitro, their effect in vivo might be diminished through rapid clearance by macrophages.

Potential Role of CD47-Directed Bispecific Antibodies in Cancer Immunotherapy
The prosperity of immunological therapy for cancer has aroused enormous passion for exploiting the novel targets of cancer immunotherapy. After the approval of blinatumomab, a bispecific antibody (bsAb) targeting on CD19 for acute lymphoblastic leukemia,

CD47(low) status on CD4 effectors is necessary for the contraction/resolution of the immune response in humans and mice. [PDF]
How do effector CD4 T cells escape cell death during the contraction of the immune response (IR) remain largely unknown. CD47, through interactions with thrombospondin-1 (TSP-1) and SIRP-α, is implicated in cell death and phagocytosis of malignant cells.
