    Vimentin Regulates Nuclear Segmentation in Neutrophils

    Researchers utilized cryo-electron tomography to examine the nuclei of mouse neutrophils, revealing the cytoplasmic enrichment of intermediate filaments on the concave regions of the nuclear envelope.

    Abstract

    Peripheral T Cell Activation, Not Thymic Selection, Expands the T Follicular Helper Repertoire in a Lupus-Prone Murine Model

    Investigators described T cell selection, activation, and T cell repertoire diversity in female mice deficient for B lymphocyte–induced maturation protein-1 in dendritic cells. These mice exhibited a lupus-like phenotype with an expanded population of T follicular helper cells.

    Abstract

    Depletion of Preexisting B Cell Lymphoma 2-Expressing Senescent Cells before Vaccination Impacts Antigen-Specific Antitumor Immune Responses in Old Mice

    Scientists used the Bcl-2 family inhibitor ABT-263 to investigate the effects of pre-vaccination senolysis on immune responses in old mice. Two different ovalbumin-containing vaccines were tested.

    Comparing HD Knockin Pigs and Mice Reveals the Pathological Role of IL-17

    By performing RNA sequencing to compare the gene expression profiles between Huntington’s disease (HD) knockin pigs and mice, researchers found that genes related to interleukin-17 (IL-17) signaling were upregulated in the HD pig brains compared to the mouse brains.

    Excessive Apoptosis of Rip1-Deficient T Cells Leads to Premature Aging

    Investigators found that T-cell-specific Rip1 KO mice showed age-related T cell changes and exhibited signs of accelerated aging-like phenotypes, including inflammation, multiple age-related diseases, and a shorter lifespan.

    AbstractGraphical Abstract

    Natural Isoaspartyl Protein Modification of ZAP70 Alters T Cell Responses in Lupus

    The authors demonstrated that isoaspartyl modifications arise within the ZAP70 protein tyrosine kinase upon T cell antigen receptor engagement. The enzyme protein L-isoaspartate O-methyltransferase evolved to repair isoaspartyl modifications in cells.

    FOXP3 Deficiency, from the Mechanisms of the Disease to Curative Strategies

    Scientists provide a comprehensive review of immune dysregulation, polyendocrinopathy, enteropathy X-linked syndrome with a specific focus on mechanistic findings, and implications for diagnostics and treatments, details of which may be highly relevant to other primary immune regulatory diseases.
