Supramolecular Assembly of Stepped‐Persistent ROS Nanogenerator for Sustained Tumor Immunotherapy
ROS catalytic systems often fail to achieve both effective tumor elimination and persistent immune activation due to their monotonous ROS production profiles. A stepped‐persistent ROS nanogenerator was developed by supramolecularly assembling multiple ROS generation modules within a nanofiber structure to simultaneously extend ROS generation duration ...

A Potential Inhibitory Profile of Liver CD68+ Cells during HCV Infection as Observed by an Increased CD80 and PD-L1 but Not CD86 Expression. [PDF]
AIM:The lack of potent innate immune responses during HCV infection might lead to a delay in initiating adaptive immune responses. Kupffer cells (KCs) and liver-infiltrating monocytes/macrophages (CD68+ cells) are essential to establish effective anti ...

PLD3 activates the lysosomal‐AKT‐NF‐κB axis to drive cellular senescence in macrophages, establishing an immunosuppressive TME by limiting the infiltration of cytotoxic T, NK, and NKT cells, which confers resistance to anti‐PD‐1 therapy. Abrine inhibits PLD3 expression, restoring antitumor immunity and synergizing with anti‐PD‐1 treatment.

DNA methylation of CD80 promoter region in EL4 and its variant cells. [PDF]
(A) The distribution of CpG dinucleotides in a region 1 kb upstream of Exon 1 of CD80 gene. Numbers refer to position relative to the 5′ end of CD80. Two CpG enriched regions (F1 and F2) were selected for Bisulfite sequencing analysis.

The Role of CD80 and CD86 In Macrophage Activation and its Regulation Following LPS Stimulation [PDF]
The binding of CD80/CD86 on the APC to CD28 on the T cell surface provides a second signal for T cell activation. While it was once believed that this interaction represented a one-way signal, resulting in T cell activation, recently, it has been ...

Rigid, bivalent CTLA-4 binding to CD80 is required to disrupt the cis CD80/PD-L1 interaction
Summary: The CTLA-4 and PD-1 checkpoints control immune responses and are key targets in immunotherapy. Both pathways are connected via a cis interaction between CD80 and PD-L1, the ligands for CTLA-4 and PD-1, respectively. This cis interaction prevents

A senolytic sonovaccine platform (SenoVac) is developed, in which senescent cell‐derived vesicles serve as broad senescent cell antigen reservior. The “2‐step” click chemistry strategy for effective lymph node delivery, and ultrasound‐triggered endosomal escape to boost cross‐presentation, ensures efficient senescent cell clearance and disease ...

CD80 Expressed by CD8+ T Cells Contributes to PD-L1-Induced Apoptosis of Activated CD8+ T Cells
Tumor cells are capable of limiting antitumor CD8+ T cell responses through their cell surface expression of PD-L1. In addition to PD-1 expressed by CD8+ T cells, PD-L1 also binds to CD80 expressed by CD8+ T cells.

A rational design DNA nanoplatform not only achieves efficient PD‐L1 degradation but also triggers robust STING signaling. The nanodevice effectively reprograms “cold” tumors, leading to potent inhibition of tumor growth and metastasis in vivo. ABSTRACT The cGAS‐STING pathway is a cornerstone of innate antitumor immunity; however, its therapeutic ...

Radiotherapy‐treated tumor membranes are integrated with Mn‐MOF nanoadjuvants to generate Mn@RM, a lymph node‐draining nanovaccine that delivers radiotherapy‐remodeled antigenic components. Mn@RM enhances dendritic cell activation, amplifies T cell‐mediated antitumor immunity, and synergizes with radiotherapy and PD‐1 blockade for combination cancer ...
