Stromal‐Derived IL‐8 Promotes M2 Macrophage Polarization via the RhoA/MRTF‐A/SRF Transcriptional Axis to Impair CD8+ T Cell Cytotoxicity in Lung Cancer

Advanced Science, EarlyView.
In the recondite pulmonary neoplastic milieu, DESMIN+ cancer‐associated fibroblasts function as the paramount stromal source of IL‐8, precipitating a deleterious immunological metamorphosis by engaging CXCR2 receptors on the myeloid lineage. This paracrine stimulus triggers a mechanotransduction cascade characterized by RhoA‐dependent actin ...

Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

Advanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

RNA Helicase DDX21 Controls CD4+ T Cell Proliferation and Promotes Inflammatory Bowel Disease via Translational Control

Advanced Science, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD) is characterized by dysregulated T cell responses. RNA helicases, including DExD‐box helicase 21 (DDX21), are pivotal in RNA metabolism, but their role in T cell‐mediated pathology during IBD remains unclear. Here, we demonstrate that DDX21 expression in CD4+ T cells correlates with cell cycle and translation ...

Canagliflozin Alleviates Diabetic Glomerular Endothelial Injury via Melibiose in a Microbiota‐Dependent Manner

Advanced Science, EarlyView.
Canagliflozin treatment reshapes the gut microbiota in DKD and elevates levels of melibiose, a metabolite derived from Roseburia intestinalis. Melibiose directly binds to and enhances the enzymatic activity of glyoxalase 1, leading to decreased methylglyoxal accumulation.

Oncolytic HSV1716 attenuates tumor-killing activity of infected primary NK cells

Frontiers in Immunology
Oncolytic herpes simplex virus type-1 (HSV1)–based therapies engage innate immune responses, including natural killer (NK) cells, which are regarded as antiviral effector cells that eliminate virus-infected tumor targets.

Engineering Immunoregenerative Therapy via an Immunomodulatory Binary Pharmacology Hydrogel Depot for Prolonged Allograft Survival

Advanced Science, EarlyView.
An immunomodulatory hydrogel (iGEL) forms spontaneously upon subcutaneous injection, acting as a tissue‐adhesive depot. It releases anti‐rejection and regenerative agents in response to inflammation, suppressing T‐cell activity, promoting vascular repair, and restoring allograft function without systemic immunosuppression.

Unbiased immunome characterisation correlates with COVID-19 mRNA vaccine failure in immunocompromised adults

Frontiers in Immunology
IntroductionCoronavirus disease 2019 (COVID-19) affects the population unequally, with a greater impact on older and immunosuppressed people.MethodsHence, we performed a prospective experimental cohort study to characterise the effect of severe acute ...

Single‐Cell Dissection of Therapy‐Induced Remodeling Uncovers a Fibroblast‐Driven Immunosuppressive Niche and Targetable Vulnerabilities in Lethal Prostate Cancer

Advanced Science, EarlyView.
Single‐cell longitudinal profiling reveals that androgen‐deprivation therapy induces a DPT+ fibroblast‐complement axis that suppresses macrophage inflammation and drives CD8+ T cell exhaustion in prostate cancer. Concurrently, resistant epithelial subpopulations persist and engage TSPAN1‐ and NRXN1‐mediated programs promoting CRPC and neuroendocrine ...

Aptamer‐Engineered Liposomal Platform Enables in Situ cDC1 Vaccination to Potentiate Immunotherapy in Prostate Cancer

Advanced Science, EarlyView.
Prostate cancer is immunologically ‘cold’, with scarce, dysfunctional type 1 conventional dendritic cells (cDC1s) that limit T cell priming. We introduce an aptamer‐targeted liposomedelivering FMS‐like tyrosine kinase 3 ligand (Flt3L) and chlorin e6 (Ce6). Ultrasound induces antigen release and cDC1s recruitment, creating an in situ cDC1 vaccine.
