    TOP STORY

    Evasion of NKG2D-Mediated Cytotoxic Immunity by Sarbecoviruses

    Researchers found that SARS-CoV-2 evaded NKG2D recognition by surface downregulation of MIC-A/B via shedding, observed in human lung tissue and COVID-19 patient serum.

    Jagged2 Targeting in Lung Cancer Activates Anti-Tumor Immunity via Notch-Induced Functional Reprogramming of Tumor-Associated Macrophages

    The authors studied the role of the Notch ligand Jagged2 on immune evasion in NSCLC. Higher expression of JAG2 in NSCLC negatively correlated with survival.

    QDPR Deficiency Drives Immune Suppression in Pancreatic Cancer

    Scientists demonstrated that the deficiency of quinoid dihydropteridine reductase (QDPR), a critical enzyme regulating biopterin metabolism, caused metabolite dihydrobiopterin (BH2) accumulation and decreased the ratio of tetrahydrobiopterin to BH2 in pancreatic ductal adenocarcinomas.

    Human NLRC4 Promotes Cancer Survival and Is Associated to Type-I Interferon Signaling and Immune Infiltration

    Investigators showed that NLR family CARD Domain Containing 4 (NLRC4) was downregulated in epithelial tumor cells of colorectal cancer patients by using spatial tissue imaging.

    Abstract

    Lack of mTORC2 Signaling in CD11c+ Myeloid Cells Inhibits Their Migration and Ameliorates Experimental Colitis

    By specific deletion of Rictor in CD11c+ myeloid cells, researchers investigated the role of mTOR complex 2 (mTORC2) signaling in dendritic cell function in mice.

    Abstract

    TNF-α Signals through ITK-Akt-mTOR to Drive CD4+ T Cell Metabolic Reprogramming, Which Is Dysregulated in Rheumatoid Arthritis

    The authors investigated whether inflammatory cytokines released by differentiating T cells amplified their metabolic changes. They found that tumor necrosis factor–α (TNF-α) released by human naïve CD4+ T cells upon activation stimulated the expression of a metabolic transcriptome.

    Abstract

    MiRNA-148a-Containing GMSC-Derived EVs Modulate Treg/Th17 Balance via IKKB/NF-κB Pathway and Treat a Rheumatoid Arthritis Model

    Scientists investigated the potential of extracellular vesicles derived from human gingival mesenchymal stem cells as a therapeutic strategy for rheumatoid arthritis.

    Threonine Dehydrogenase Regulates Neutrophil Homeostasis but Not H3K4me3 Levels in Zebrafish

    Investigators revealed that, in zebrafish hematopoiesis, L-threonine dehydrogenase (tdh) was preferentially expressed in neutrophils.

    B Cells and Atherosclerosis: A HIV Perspective

    Scientists review the multifaceted functions of B cells in atherosclerosis, with a specific focus on HIV. Unique to atherosclerosis is the pivotal role of natural antibodies, particularly those targeting oxidized epitopes abundant in modified lipoproteins and cellular debris.
