    DR3 Stimulation of Adipose Resident ILC2s Ameliorates Type 2 Diabetes Mellitus

    Investigators established that expression of Death Receptor 3 (DR3), a member of the tumor necrosis factor superfamily, on visceral adipose tissue-derived murine and peripheral blood human group 2 innate lymphoid cells was inducible by IL-33.

    The
    Innate Immune Effector ISG12a Promotes Cancer Immunity by Suppressing the Canonical Wnt/β-Catenin Signaling Pathway

    ISG12a was found to be expressed at low levels in gastrointestinal cancer, represented by hepatocellular cancer and gastric cancer, and identified as a tumor suppressor that affects clinical prognosis.

    Allogeneic
    Vγ9Vδ2 T-Cell Immunotherapy Exhibits Promising Clinical Safety and Prolongs the Survival of Patients with Late-Stage Lung or Liver Cancer

    Researchers developed a novel formula to improve the expansion of peripheral γδ T cells from healthy donors. Then, they used a humanized mouse model to validate the therapeutic efficacy of expanded γδ T cells in vivo; furthermore, the expanded γδ T cells were adoptively transferred into late-stage liver and lung cancer patients.

    IL-10 Variants Elicit Potent Immunomodulatory Effects at Low Ligand Doses

    The authors explored whether the stability of the IL-10 receptor complex contributed to the immunomodulatory potency of IL-10.

    Abstract

    Sarcoidosis
    Exosomes Stimulate Monocytes to Produce Pro-Inflammatory Cytokines and CCL2

    Scientists found that bronchoalveolar lavage fluid exosomes from sarcoidosis patients, but not from healthy individuals, induced a dose-dependent elevation of intracellular IL-1β in monocytes.

    Multiplexed Detection and Isolation of Viable Low-Frequency Cytokine-Secreting Human B Cells Using Cytokine Secretion Assay and Flow Cytometry (CSA-Flow)

    Researchers examined how adaptation of the CSA in combination with multiparametric flow-cytometry may enable simultaneous isolation of multiple, low-frequency, cytokine-secreting cells.

    RNA-Seq
    Profiling of Microdissected Glomeruli Identifies Potential Biomarkers for Human IgA Nephropathy

    Scientists collected glomeruli from biopsy specimens from immunoglobulin A nephropathy patients with relatively preserved kidney function and from normal kidney cortices by hand microdissection and performed RNA-seq.

    Abstract

    A
    Single-Domain Bispecific Antibody Targeting CD1d and the NKT T-Cell Receptor Induces a Potent Antitumor Response

    Researchers describe how single-domain antibodies (VHH), specific for the human major histocompatibility complex class I-like molecule CD1d, could modulate the function of CD1d-restricted T cells and how one VHH specifically induced strong type I natural killer T (NKT) cell activation.

    Abstract

    Omental
    Macrophages Secrete Chemokine Ligands That Promote Ovarian Cancer Colonization of the Omentum via CCR1

    Investigators report that omental macrophages promoted the migration and colonization of ovarian cancer cells to the omentum through the secretion of chemokine ligands that interacted with chemokine receptor 1.
