Granzyme B PET Imaging Reveals Lgmn+ Macrophage‐Mediated Immune Evasion and Guides Immunotherapy in EGFR‐TKI‐Resistant NSCLC

open access: yesAdvanced Science, EarlyView.
Graphical illustration of 68Ga‐GZB PET/CT imaging reveals immune dynamics post‐EGFR‐TKI resistance in NSCLC; Lgmn+ macrophages‐derived Lgmn‐containing extracellular vesicles inhibit glycolysis, induce CD8+ T cell exhaustion, and targeting Lgmn restores immunotherapy sensitivity.

High‐Density Type I Collagen Promotes IFN‐γ+ CD8+ T Cell Exhaustion via SAT1‐ASS1‐Mediated Glutamine Accumulation and Ferroptosis in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
High‐density type I collagen promotes glutamine (Gln) accumulation–related ferroptosis of TNBC cells via the spermidine/spermine N1‐acetyltransferase 1 (SAT1)‐ argininosuccinate synthase (ASS1) signaling pathway, thus depriving immune cells of Gln supply and inducing IFN‐γ+ CD8+ T cell exhaustion in the TME.

Human CD3 complex is required for the generation of T-cell receptor-like chimeric antigen receptor targeting WT1 in natural killer cells

open access: yesCancer Immunology, Immunotherapy
Chimeric antigen receptor-natural killer (CAR-NK) cells represent a promising cellular immunotherapy platform for various cancers, offering a favorable clinical safety profile and potential to generate off-the-shelf products. However, broader application

Platycodon grandiflorus–Derived Nanovesicles Sensitize Gastric Cancer to T Cell Killing via Ferroptosis‐Driven Membrane Mechanical Remodeling

open access: yesAdvanced Science, EarlyView.
Plant‐derived nanovesicles from Platycodon grandiflorus act as bioactive lipid delivery platforms that transport γ‐linolenic acid into gastric cancer cells. This lipid cargo promotes ferroptotic lipid peroxidation, remodels membrane mechanics, and increases tumor‐cell susceptibility to cytotoxic T‐cell attack.

SPRED2 Negatively Regulates CD8+ T Cell‐Mediated Antitumor Immunity in Breast Cancer

open access: yesAdvanced Science, EarlyView.
Sprouty‑related EVH1 domain containing 2 (SPRED2) restrains Ras/Raf/ERK signaling in CD8+ T cells. Host SPRED2 deficiency enhances T‐cell survival, cytotoxicity, and memory‐like phenotypes, reducing primary tumor growth and endpoint lung metastatic burden in breast cancer models.

Potential role of B7-1 and CD28 molecules in immunosuppression in leprosy

open access: yes, 1998
In order to understand the mechanism of unresponsiveness towards Mycobacterium leprae antigens in leprosy, we evaluated the role of M. lepraesonicate antigens in regulating the expression of the costimulatory molecules B7-1, CD28, intercellular adhesion ...

CXCL3 Antagonism Reverses Systemic Antitumor Immune Memory Impairment Associated With High Tumor Burden and Sensitizes Anti‐PD‐1 Therapy

open access: yesAdvanced Science, EarlyView.
This study reveals that large tumors secrete more chemokine CXCL3, which recruits immunosuppressive neutrophils to the periphery, thereby impairing the activation and memory of systemic tumor‑reactive CD8+ T cells. CXCL3 antagonism restores systemic immune memory and enhances the antitumor efficacy of anti‑PD‑1 therapy, offering a potential strategy to

The CD28-B7 costimulatory pathway and its role in autoimmune disease

open access: yes, 1997
The activation of naive CD4+ T cells requires two discrete signals: a signal delivered by the T cell receptor following recognition of antigen and an accessory signal transduced when costimulatory receptors interact with their ligands.

A Multi‐Targeting Chimeric Antigen Receptor‐T Cell Platform to Overcome Antigen Heterogeneity in the Treatment of Non‐Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
A dual‐transmembrane Bicephali CAR‐T platform simultaneously targets CD276 and NKG2D ligands to address antigen heterogeneity in non‐small cell lung cancer. By improving immune synapse formation, mitochondrial fitness, antioxidant capacity, and stem‐like persistence, this design enhances durable tumor control and provides a versatile strategy to ...

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

open access: yesAdvanced 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.
