    Clinical
    and Biological Subtypes of B-Cell Lymphoma Revealed by Microenvironmental Signatures

    Scientists performed a transcriptomic analysis of the microenvironment of 4,655 DLBCLs from multiple independent cohorts and described four major lymphoma microenvironment categories that associate with distinct biological aberrations and clinical behavior.

    Laminin
    γ2–Mediating T Cell Exclusion Attenuates Response to Anti–PD-1 Therapy

    The up-regulation of laminin γ2 predicted the attenuated efficacy of anti–PD-1 drugs and was associated with unfavorable outcomes in patients with lung cancer or esophageal cancer.

    Engineering
    Advanced Logic and Distributed Computing in Human CAR Immune Cells

    Investigators developed an inhibitory feature, achieving a three-input logic, and demonstrated that this programmable system was functional in diverse adaptive and innate immune cells.

    Galectin-9
    Interacts with PD-1 and TIM-3 to Regulate T Cell Death and Is a Target for Cancer Immunotherapy

    The authors showed that PD-1 contributed to the persistence of PD-1+TIM-3+ T cells by binding to the TIM-3 ligand galectin-9 and attenuated Gal-9/TIM-3-induced cell death.

    Selective
    Recruitment of γδ T Cells by a Bispecific Antibody for the Treatment of Acute Myeloid Leukemia

    Scientists designed an alternative engager molecule, a bispecific antibody that could simultaneously bind to the Vγ9 chain of the Vγ9Vδ2+ γδ T cell receptor and to AML target antigen, CD123, to selectively recruit Vγ9+ γδ T cells rather than pan T cells to target AML blasts.

    Activation of Human Macrophages Enhances Tissue Factor Expression and Production of Extracellular Vesicles

    To understand if polarization of macrophages could lead to a procoagulant macrophage subset, investigators polarized human monocyte derived macrophages to a proinflammatory and an alternative activation state.

    IL36
    Is a Critical Upstream Amplifier of Neutrophilic Lung Inflammation in Mice

    Researchers combined in vivo and in vitro approaches using primary mouse and human cells, as well as, acute and chronic mouse models of lung inflammation to provide mechanistic insight into the intercellular signaling pathways and mechanisms through which IL-36 promotes lung inflammation.

    Significance
    of Abnormal 53BP1 Expression as a Novel Molecular Pathologic Parameter of Follicular-Shaped B-Cell Lymphoid Lesions in Human Digestive Tract

    Scientists evaluated the potential of immunofluorescence-based analysis of 53BP1 expression in differentiating malignant lymphomas from benign lymphoid lesions.

    The
    GSK3β-β-Catenin-TCF1 Pathway Improves Naive T Cell Activation in Old Adults by Upregulating miR-181a

    Investigators identified TCF1 as a transcriptional regulator of pri-miR-181a. A decline in TCF1 levels in old individuals accounted for the reduced miR-181a expression impairing TCR signaling.
