    Metabolic Flexibility Determines Human NK Cell Functional Fate in the Tumor Microenvironment

    Using cancer patient samples and proteomics, scientists found that human NK cell dysfunction in the tumor microenvironment was due to suppression of glucose metabolism via lipid peroxidation-associated oxidative stress.

    Chronic Stress Physically Spares but Functionally Impairs Innate-Like Invariant T Cells

    Scientists report that long-term stress surprisingly abrogates both T helper 1 (TH1)- and TH2-type responses orchestrated by invariant natural killer T cells.

    DDAH2 Suppresses RLR-MAVS–Mediated Innate Antiviral Immunity by Stimulating Nitric Oxide–Activated, Drp1-Induced Mitochondrial Fission

    Researchers identified dimethylarginine dimethylaminohydrolase 2 (DDAH2) as a potent regulator of the RIG-I–like receptor-mediated antiviral response in human and mouse.

    Abstract

    An IgD-FC-Ig Fusion Protein Restrains the Activation of T and B Cells by Inhibiting IgD-IgDR-Lck Signaling in Rheumatoid Arthritis

    Scientists investigated the downstream signaling pathways by which IgD activated T cells as well as the possible role of IgD in the T–B interaction.

    Abstract

    Automated Production of CCR5-Negative CD4+-T Cells in a GMP-Compatible, Clinical Scale for Treatment of HIV-Positive Patients

    Investigators present a GMP-compatible mRNA electroporation protocol for the automated production of CCR5-edited CD4+-T cells in the closed CliniMACS Prodigy system.

    Cromolyn Inhibits the Secretion of Inflammatory Cytokines by Human Microglia (HMC3)

    To better understand the mechanistic effect cromolyn has in slowing down or halting the neuroinflammatory response associated with Alzheimer’s disease progression, the authors tested the effect of cromolyn to dampen the inflammatory response in the human HMC3 microglia cell line.

    Abstract

    Overlapping and Distinct Features of Viral and Allergen Immunity in the Human Lung

    The authors explore how advances in the study of human immunology have shaped the understanding of the resident immune network and its response to two of the most commonly encountered inflammatory stimuli in the airways: viruses and allergens.
