    New Lymphoid-Primed Progenitor Marked by Dach1 Downregulation Identified with Single Cell Multi-Omics

    Through single-cell RNA sequencing, researchers identified the expression of Dach1 and associated genes in this fraction as being coexpressed with myeloid/stem genes but inversely correlated with lymphoid genes.

    Mobilizes Immune Cells that Exacerbate Hemorrhagic Transformation in Stroke

    Scientists determined the impact of tissue plasminogen activator (tPA) on immune cells and investigated the association between observed immune alteration with hemorrhagic transformation in ischemic stroke patients and in a rat model of embolic stroke.

    Abstract

    Biodiversity
    Intervention Enhances Immune Regulation and Health-Associated Commensal Microbiota among Daycare Children

    Investigators conducted the first human intervention trial in which urban environmental biodiversity was manipulated to examine its effects on the commensal microbiome and immunoregulation in children.

    Cryopreservation Impairs 3D Migration and Cytotoxicity of Natural Killer Cells

    Scientists report that tumor cells embedded in a 3-dimensional collagen gel were killed by cryopreserved natural killer (NK) cells at a 5.6-fold lower rate compared to fresh NK cells.

    Phenotypic
    and Functional Characterization of First-Trimester Human Placental Macrophages, Hofbauer Cells

    The authors identified a number of factors that Hofbauer cells (HBCs) secreted that could affect placental angiogenesis and remodeling. They determined that HBCs had the capacity to play a defensive role, where they were responsive to Toll-like receptor stimulation and were microbicidal.

    Naive
    CD8+ T Cells Expressing CD95 Increase Human Cardiovascular Disease Severity

    Using mass cytometry, scientists uncovered a naive CD8+ T cell population expressing CD95 that was enriched in patients with high compared with low cardiovascular disease.

    Abstract

    HOPS/Tmub1
    Involvement in the NF-kB-Mediated Inflammatory Response through the Modulation of TRAF6

    The authors found that HOPS enhanced NF-κB activation leading to increase transcription of inflammatory mediators, through the reduction of IκBα stability.

    Immunomodulatory Activity of IR700-Labelled Affibody Targeting HER2

    Irradiating a co-culture of immature dendritic cells (DCs) and cancer cells exposed to light-activated ZHER2:2395-IR700 enhanced DC maturation, as indicated by augmented expression of CD86 and HLA-DR.

    Identification
    of Immune Landscape Signatures Associated with Clinical and Prognostic Features of Hepatocellular Carcinoma

    Investigators combined immune landscape signatures with hepatocellular carcinoma clinical and prognostic features to classify them into distinct subtypes. The immunogenomic profiles, stromal cell features and immune cell composition of the subtypes were then systematically analyzed.

    Identification
    of a Distal Locus Enhancer Element That Controls Cell Type–Specific TNF and LTA Gene Expression in Human T Cells

    Scientists showed that a highly conserved NFAT binding site within the distal noncoding element hHS-8 coordinately controlled TNF and LTA gene expression in human T cells.

    Cell-Free DNA in Plasma as an Essential Immune System Regulator

    Researchers showed that cell-free DNA presence and clearance in plasma of healthy individuals played an indispensable role in immune system regulation.

    Assessment
    of Long Non-Coding RNA Expression Reveals Novel Mediators of the Lung Tumor Immune Response

    Scientists identified the landscape of tumor-infiltrating immune cells in the context of long non-coding RNA, known regulators of gene expression. They examined the lncRNA profiles of lung adenocarcinoma tumors by interrogating RNA sequencing data from microdissected and non-microdissected samples.
