Designer Solid Self‐Emulsifying Nanovaccines Enable Dual Modulation of Dendritic Cells and T Cells for Potent Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
A solid self‐emulsifying (SSE) platform is loaded with peptide antigens and CpG to form the SSE vaccine. An ApoE‐enriched corona promotes dendritic cell internalization, enabling antigen presentation and T cell activation. Squalene from the SSE also sensitizes T cells by promoting lipid raft formation.

CD27 and ICOS as Targets of PD‐1/PD‐L1 Signaling to Regulate Resident Memory CD8+ T‐Cell‐Mediated Pulmonary Protection and Pathology

open access: yesAdvanced Science, EarlyView.
Here it is revealed that the costimulatory receptors CD27 and ICOS are essential for the long‐term maintenance of PD‐1high CD8+ TRM cells following influenza infection. PD‐L1 blockade enhances the proliferation and activation of these cells through Nur77 activation downstream of the CD27/ICOS signaling axis, thereby boosting host immunity against ...

Efferocytosis‐Driven Polyamine Metabolism in Macrophages Enhances Cancer Stem Cell Enrichment after Chemotherapy in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
Chemotherapy‐induced efferocytosis drives ovarian cancer stem cell enrichment. By engulfing apoptotic cancer cells, macrophages upregulate ODC1 and produce putrescine, which elevates osteopontin (OPN) expression. Secreted OPN then activates the CD44 receptor on cancer cells, promoting stemness and chemoresistance.

A Rationally Engineered Spleen‐Tropic One‐Component Lipid‐mRNA Complex (OncoLRC) for Cancer Vaccines

open access: yesAdvanced Science, EarlyView.
OncoLRC, a one‐component lipid‐mRNA complex, enables efficient spleen‐targeted delivery at an exceptionally low lipid‐to‐mRNA mass ratio (1.5:1), robustly activates immune responses, inhibits tumor growth, and synergizes with checkpoint blockade, presenting a next‐generation platform for mRNA vaccines.

Folic Acid‐Modified Ginger‐Derived Exosome‐Like Nanoparticles Co‐Delivering Sunitinib Suppress Renal Cell Carcinoma via PI3K‐Akt Pathway Inhibition, P‐gp Downregulation, and Macrophage Reprogramming

open access: yesAdvanced Science, EarlyView.
FPD‐GELNs co‐deliver Su and bioactive components. This active‐passive dual‐targeting strategy suppresses the progression of RCC through the following mechanisms: 1) inhibition of the PI3K‐Akt signaling pathway; 2) downregulation of ABCB1/P‐gp to enhance the chemosensitivity of RCC to Su; and 3) reprogramming of macrophages toward M1 polarization and ...

Spatial Profiling Reveals Distinct Molecular and Immune Evolution of Mouse Lung Adenocarcinoma Precancers with or Without Carcinogen Exposure

open access: yesAdvanced Science, EarlyView.
Tumor evolution in lung adenocarcinoma is shaped by genetic alterations and spatial immune dynamics. By integrating whole‐exome sequencing, imaging mass cytometry, and spatial transcriptomics across two mouse models, this study reveals how mutational burden, immune infiltration, and cell–state interactions evolve during early and late carcinogenesis ...

PBRM1 Deficiency Reshapes an Immune Suppressive Microenvironment Through Epigenetic Tuning of PBRM1‐KDM5C‐IL6 Axis in ccRCC

open access: yesAdvanced Science, EarlyView.
PBRM1 ranks as the second most commonly mutated gene in ccRCC. This study reveals that PBRM1 loss promotes an immunosuppressive microenvironment by elevating M2 TAMs via the KDM5C–IL‐6 axis. These M2 TAMs, along with CAFs, form a barrier that excludes CD8+ T cells. Targeting IL‐6 synergizes with anti‐PD1 therapy, offering a promising strategy for PBRM1‐
