Immune Checkpoint Therapy Drives Maturation of a Cellular Neighborhood Nucleated by T Cell-APC Triads Enabling Spatially Compartmentalized Tumor Immunity

This study demonstrates that immune checkpoint therapy drives the maturation of a specific "immunity-promoting" cellular neighborhood nucleated by T cell-APC triads, which undergoes spatiotemporal compartmentalization to sustain and amplify cytotoxic T cell responses for effective tumor rejection.

Anti-HIV Immunotoxin and Antibody-Drug Conjugate Display Both Common and Distinct Effects in Killing Target Cells

This study demonstrates that while both an immunotoxin and an antibody-drug conjugate targeting HIV-infected cells ultimately induce cell death, they exhibit distinct temporal metabolic and transcriptional responses, with the immunotoxin triggering rapid stress and apoptosis pathways compared to the delayed effects of the antibody-drug conjugate.

Phagocytic Clearance of SARS-CoV-2 Nucleocapsid- and RNA-Containing Immune Complexes Drives Inflammatory Cytokine Production and Endothelial Dysfunction

This study demonstrates that phagocytic clearance of SARS-CoV-2 RNA- and nucleocapsid-containing immune complexes by monocytes drives inflammatory cytokine production and endothelial dysfunction, suggesting that this IgG-mediated mechanism contributes to severe COVID-19 pathology and potentially the severity of other viral infections.

Using Imaris to rigorously track PET-defined sites of lung inflammation in Mycobacterium tuberculosis-exposed non-human primates

This paper proposes and validates a novel Imaris-based pipeline for rigorously tracking and characterizing 3D PET-defined lung inflammation sites in *Mycobacterium tuberculosis*-exposed non-human primates, offering superior alignment, automated segmentation, and detailed morphological metrics compared to traditional 2D slice-based analysis methods.

Overlapping MHC class I/II Epitopes Program cDC1-like Differentiation of Monocyte-Derived Dendritic Cells via mTORC1 Signaling Inhibition

This study reveals that overlapping MHC class I/II epitopes drive monocyte-derived dendritic cells to adopt a cDC1-like phenotype capable of initiating type 1 immunity by inhibiting mTORC1 signaling, a mechanism that enhances the efficacy of clinical vaccine products and offers new avenues for cancer immunotherapy.
