Suppression of immune responses in collagen-induced arthritis by a rationally designed CD80-binding peptide agent [PDF]

, 2007
Objective. The CD80/CD86-CD28/CD152 costimulatory pathways transmit signals for CD4+ T cell activation and suppression and are critically involved in the pathogenesis of rheumatoid arthritis (RA).

CD152 Ligation by CD80 on T Cells Is Required for the Induction of Unresponsiveness by Costimulation-Deficient Antigen Presentation [PDF]

, 2000
Two apparently contradictory observations have been made concerning peripheral T cell tolerance; costimulation-deficient Ag presentation leads to unresponsiveness, and CTLA4 (CD152) ligation is required for unresponsiveness to be induced.

Effects of CTLA4-Ig on human monocytes

Inflammation and Regeneration, 2017
Background Abatacept, a CTLA4-Ig fusion protein attenuates T cell activation by inhibiting the CD80/86-CD28 costimulatory pathway that is required for the proper T cell activation and thus displays beneficial effects in the treatment of rheumatoid ...

Ultrasound‐Recharged Sub‐Nanometer Palladium Catalysts for on‐Demand and Self‐Terminating Bioorthogonal Prodrug Activation in Cancer Therapy

Advanced Science, EarlyView.
Safe and precise bioorthogonal therapy of tumors was achieved by an ultrasound‐responsive heterostructured nanoreactor with on‐demand catalytic activity. Under piezoelectric catalysis, the system undergoes reversible Pd2+/Pd0 redox cycling, concurrently enabling spatiotemporally controlled prodrug activation and self‐terminating catalytic dose ...

A Plant Photoregulator‐Inspired S‐Type Heterojunction System for Diabetic Keratopathy via Tri‐Modal Light‐Driven Immunometabolic Reprogramming, Tissue Repair, and Antibacterial Activity

Advanced Science, EarlyView.
To address the multifaceted imbalance in diabetic keratopathy, a light‐responsive biomimetic platform (WCNx‐Rh2) is developed and integrates glucose degradation, immune modulation, and antibacterial defense through a designed heterojunction and screened immunomodulator. WCNx‐Rh2 reduces AGEs/ROS and inflammatory signaling, reprogramming dendritic cells

NIR‐II Light‐Triggered Electron Flow Initiates Cuproptosis‐Centered Thermoelectric‐Immunotherapy for Breast Cancer

Advanced Science, EarlyView.
A NIR‐II light‐activatable thermoelectric nanoreactor converts surface‐bound Cu2+ into bioactive Cu+ via directed electron flow. This spatiotemporally controlled reduction triggers potent cuproptosis and immunogenic cell death, eradicating primary tumors and, together with aPD‐1 therapy, suppressing metastases while establishing durable immune memory ...

Autoantigen mRNA‐LNP Vaccination Drives Therapeutic Efficacy in Preclinical Models for Autoimmunity

Advanced Science, EarlyView.
Systemic and intramuscular delivery of autoantigen mRNA via lipid nanoparticles reprograms antigen‐presenting cells toward a mature, homeostatic state, driving antigen‐specific T cell exhaustion and providing therapeutic efficacy across autoimmune disease models.

Targeting p21‐High Senescent Kupffer Cells Nanotherapeutically Potentiates Antitumor Immunity in Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

Advanced Science, EarlyView.
Schematic illustration of a biomimetic SKEV@AAV platform targeting p21‐high senescent Kupffer cells (sKCs) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). p21‐high sKCs accumulate in the PVTT microenvironment and establish an immunosuppressive, SASP‐rich environment that facilitates tumor cell proliferation and immune evasion.
