Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

Advanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

CD169+ Macrophage‐Targeted Immunomodulator to Restore Phagocytic Function and Enhance Antigen Presentation for Lymphatic Metastasis Eradication

Advanced Science, EarlyView.
A CD169+ macrophage‐targeted immunomodulator (G‐LNP@S‐D) is developed to co‐deliver a SHP2 inhibitor and STING agonist, thereby restoring phagocytic function, enhancing antigen presentation by CD169+ macrophages, and promoting T cell priming to eradicate lymphatic metastasis.

Endocytic Recycling of MHC Class I Molecules in Non-professional Antigen Presenting and Dendritic Cells

Frontiers in Immunology, 2019
Major histocompatibility complex class I (MHC I) molecules are glycoproteins that display peptide epitopes at the cell surface of nucleated cells for recognition by CD8+ T cells.

Host immune response to cytomegalovirus [PDF]

, 1987
To confirm that immediate-early (IE) genes of murine cytomegalovirus (MCMV) give rise to antigens recognized by specific cytolytic T lymphocytes (CTL), a 10.8-kilobase fragment of MCMV DNA which is abundantly transcribed at IE times was transfected into ...

MARCO+ Tumor‐Associated Macrophages Impede CD8+ T Cell Immunity to Facilitate Immunotherapy Resistance in Renal Cell Carcinoma

Advanced Science, EarlyView.
MARCO+ TAMs dominate restrained cytotoxicity of CD8+ CTLs and ICB resistance in RCC. Mechanically, MARCO impairs MHC‐I‐mediated neoantigen cross‐presentation via the SOCS1‐JAK1‐STAT1‐NLRC5 signaling cascade in TAMs. Targeted MARCO treatment boosts macrophage antigen cross‐presentation and empowers CD8+ T cells, thereby potentiating ICB efficacy ...

Pro-inflammatory responses after peptide-based cancer immunotherapy

Heliyon
Therapeutic vaccinations are designed to prevent cancer by inducing immune responses against tumor antigens. in cancer cells, tumor-associated antigens (TAA) or tumor-specific (mutated) derived peptides are presented within the clefts of main ...

Fe‐S Protein FDX1 Triggers Tumor‐Intrinsic Innate Immunity via Mitochondrial Nucleic Acids Release to Orchestrate Ferroptosis in CCRCC

Advanced Science, EarlyView.
Restoration of the mitochondrial Fe–S protein FDX1 suppresses clear cell renal cell carcinoma by coupling ferroptosis with tumor‐intrinsic innate immune activation. FDX1 induces mitochondrial dysfunction and mtDNA/mt‐dsRNA release, activating cGAS–STING and RIG‐I/MDA5–MAVS signaling to elicit type I interferon responses, thereby promoting antigen ...

The Immune Microenvironment in Liver Cancer: From Analysis to Targeting

Advanced Science, EarlyView.
This review explores how smart nanomedicines overcome the immunosuppressive tumor microenvironment in liver cancer. It details targeted delivery strategies and immune reprogramming mechanisms, including remodeling abnormal physiology, modulating metabolism, and inducing immunogenic cell death. The article highlights the paradigm shift toward multimodal
