    A RORγt+ Cell Instructs Gut Microbiota-Specific Treg Cell Differentiation

    The authors investigated the cells and molecular components required for induced Treg cell differentiation. They found that antigen presentation by cells expressing RORγt, rather than by classical dendritic cells, was required and sufficient for induction of Treg cells.

    An Intercellular Transfer of Telomeres Rescues T Cells from Senescence and Promotes Long-Term Immunological Memory

    Scientists showed that some T cells elongated telomeres by acquiring telomere vesicles from antigen-presenting cells independently of telomerase action.

    Trafficking between Clonally Related Peripheral T Helper Cells and Tissue-Resident T Helper Cells in Chronic GVHD

    Adoptive transfer experiments showed that tissue-resident T helper (Trh) cells from graft-versus-host-disease (GVHD) target tissues gave rise to peripheral T helper (Tph) cells in the blood, and conversely, Tph cells from the blood gave rise to Trh cells in GVHD target tissues.

    Abstract

    CD8+ T Cell Memory Is Sustained in Mice by Hepatic Stellate Cells

    Researchers engineered a mouse named L15R that expressed IL-15R in hepatic stellate cells at normal levels, but not in other liver cells.

    The Amino Acid Homoarginine Inhibits Atherogenesis by Modulating T Cell Function

    Scientists investigated the effect of homoarginine supplementation on atherosclerotic plaque development with a particular focus on inflammation.

    Dendritic Cell-Derived IL-27 p28 Regulates T Cell Program in Pathogenicity and Alleviates Acute Graft-Versus-Host Disease

    Utilizing mice with IL-27 p28 deficiency in dendritic cells, investigators demonstrated that IL-27 p28 deficiency resulted in impaired Treg cell function and enhanced effector T cell responses, corresponding to aggravated acute graft-versus-host disease in mice.

    Mapping Autophagosome Contents Identifies Interleukin-7 Receptor-α as a Key Cargo Modulating CD4+ T Cell Proliferation

    The authors created a transgenic mouse model to enable direct mapping of the proteinaceous content of autophagosomes in primary cells by LC3 proximity labeling.

    Cytotoxic CD8+ T Cells May Be Drivers of Tissue Destruction in Sjögren’s Syndrome

    Quantitative analyses of CD4+ T cell subsets and of CD8+ T cells in the labial salivary glands from untreated patients with primary Sjögren’s syndrome revealed that activated CD8+ cytotoxic T cells were the most prominent T cells in these infiltrates.

    Escin Suppresses Immune Cell Infiltration and Selectively Modulates Nrf2/HO-1, TNF-α/JNK, and IL-22/STAT3 Signaling Pathways in Concanavalin A-Induced Autoimmune Hepatitis in Mice

    Researchers investigated the possible protective effect of escin, the active constituent of a natural mixture of triterpene saponin glycoside, against immune-mediated hepatitis driven by concanavalin A and elucidated its possible underlying mechanisms.

    How the Immune System Shapes Neurodegenerative Diseases

    Scientists review the sometimes-dichotomous roles played by immune cells during neurodegenerative diseases and explore how brain trauma can serve as a disease initiator or accelerant.
