T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Generation of CCR4/CD7 Bispecific CAR‐T Cells Resistant to Fratricide and Exhaustion

Advanced Science, EarlyView.
The applications of CAR T‐cell therapy in T‐cell malignancies face limitations such as fratricide, effector‐cell exhaustion, and antigen‐escape. Herein, we developed fratricide‐ and exhaustion‐resistant CAR‐T cells that targeted CCR4 and CD7 simultaneously, with optional EGFRt safety switch. Additionally, scRNA‐seq unveiled new molecular targets, which

PRELID1 and VDAC3 Coordinate a Senescence‐Like State in Germinal Center B Cells to Promote IL‐7–Driven Antitumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
Colorectal cancer is characterized by an immunosuppressive microenvironment that limits immunotherapy efficacy. We identify a senescence‐like state in germinal center B cells driven by the PRELID1–VDAC3 axis, which promotes IL‐7 secretion, alleviates CD8+ T‐cell exhaustion, and enhances antitumor immunity. Targeting this pathway improves responsiveness

One‐Step Glycoengineering of NK Cells With High‐Affinity Siglec Ligands for Cancer Immunotherapy

Advanced Science, EarlyView.
This study develops an engineered NmCSS enzyme with improved activity for bulky group modified sialic acids, enabling efficient synthesis of structurally diverse sialoside analogs in a single step. Glycan microarray screening identified Siglec high‐affinity ligands, which were incorporated onto natural killer (NK) cells via a one‐pot enzymatic system ...

Expression of cytotoxic mediators (perforin, granzyme B, FAS, and FAS-l) in renal allograft biopsies [PDF]

Einstein (São Paulo), 2006
Objectives: To analyze the in situ expression of perforin, granzymeB, FAS-L and FAS in renal allograft biopsies by means ofimmunohistochemistry and correlate these findings with the degreeof histologic rejection and allograft outcome.

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

A Spatiotemporally Controlled Nanoplatform for Photothermal BRD4 Degradation Enables Synergistic Cancer Immunotherapy

Advanced Science, EarlyView.
A GSH‐responsive MOF nanoplatform acts as a Photothermolysis‐Targeting Conjugate (PTTAC). Through sophisticated step‐wise nuclear delivery, it enables NIR‐II light‐triggered photothermal degradation of BRD4. This precise strategy induces robust immunogenic cell death (ICD) and powerfully synergizes with anti‐PD‐L1 blockade to elicit a potent systemic ...
