Delivery of CD47 blocker SIRPα-Fc by CAR-T cells enhances antitumor efficacy

Journal for ImmunoTherapy of Cancer, 2022
Background Chimeric antigen receptor (CAR) T cell therapy has been successfully applied in treating lymphoma malignancies, but not in solid tumors. CD47 is highly expressed on tumor cells and its overexpression is believed to inhibit phagocytosis by ...

Autophagy Orchestrates Anti‐Tumor Immunity to Enhance Chemosensitivity via the FBXW2/C/EBPβ/TIMP‐2 Axis in Colorectal Cancer

Advanced Science, EarlyView.
Chemotherapy leverages tumor‐cell autophagy to reshape the colorectal cancer immune microenvironment. Autophagy degrades FBXW2 to promote C/EBPβ‐mediated TIMP‐2 transcription and MMP‐9 suppression, driving intra‐tumoral CD8+ T‐cell infiltration. Targeting MMP‐2/9 or restoring TIMP‐2 overcomes chemo‐resistance in autophagy‐deficient tumors. ABSTRACT The

Oncolytic Newcastle-disease-virus-mediated CD47 blockade in preclinical melanoma and pancreatic cancer models

Molecular Therapy: Oncology
Newcastle disease virus (NDV) exhibits strong immunostimulatory activity and a favorable safety profile, but its moderate monotherapy efficacy may be improved through combination therapies.

Leveraging Microphysiological Systems to Facilitate Neutrophil‐Based Cancer Immunotherapy

Advanced Science, EarlyView.
Microphysiological systems are emerging as powerful human‐relevant platforms for studying neutrophil biology in cancer. Current applications of spheroids, organoids, and organ‐on‐a‐chip models are reviewed, together with future opportunities in behaviorome profiling, multi‐omics integration, personalized medicine, immune crosstalk, and multi‐organ ...

Degrading GPX4 via Biomimetic Nanoparticle‐Mediated In Situ Synthesis of Deep‐Learning‐Designed Binder‐Degron Chimeras for Prostate Cancer Therapy

Advanced Science, EarlyView.
A deep‐learning‐designed binder is fused to a combinatorial degron to create a binder‐degron chimera (bdC) that recruits the CUL2‐RING ubiquitin ligase complex. Encapsulation in a prostate‐cancer‐targeted, CD47‐camouflaged nanocarrier enables tumor‐specific in situ bdC expression, triggering GPX4 degradation and ferroptosis, thereby establishing a ...

T‐Cell Remodeling in Renal Fibrosis: From Acute Injury to Chronic Kidney Disease

Advanced Science, EarlyView.
This Review presents renal fibrosis as a sequence of overlapping T‐cell programs, from chemokine‐guided recruitment and metabolic activation to maladaptive polarization, tertiary lymphoid structure formation, tissue residency, exhaustion, and senescence.

Checkpoint‐Directed Glycoengineering Reprograms the Vascular Lumen for Siglec‐Mediated Immune Regulation

Advanced Science, EarlyView.
Checkpoint‐directed glycoengineering installs sialylated ligands on the donor vascular lumen during ex vivo preservation, creating a localized Siglec‐7/9‐engaging interface. The engineered glycocalyx suppresses immune‐cell activation, complement deposition, and microvascular injury in arterial and kidney allografts while preserving endothelial ...

Targeted CD47 checkpoint blockade using a mesothelin-directed antibody construct for enhanced solid tumor-specific immunotherapy

Cancer Immunology, Immunotherapy
The immune checkpoint CD47 is highly upregulated in several cancers as an innate immune escape mechanism. CD47 delivers a “don’t eat me” signal to its co-receptor signal regulatory protein α (SIRPα), thereby inhibiting phagocytosis.
