    Human T Cells Engineered with a Leukemia Lipid-Specific TCR Enables Donor-Unrestricted Recognition of CD1c-Expressing Leukemia

    Researchers showed that human T cells engineered to express an methyl-lysophosphatidic acid (mLPA)-specific TCR, targeted diverse CD1c-expressing leukemia blasts in vitro and significantly delayed the progression of three models of leukemia xenograft in NSG mice, an effect that was boosted by mLPA-cellular immunization.

    Context-Dependent Immunomodulatory Effects of MEK Inhibition are Enhanced with T-Cell Agonist Therapy

    Investigators modeled tumor-specific MEK inhibition (MEKi) through CRISPR/Cas-mediated genome editing of tumor cells and pharmacologic MEKi with cobimetinib in a RAS-driven model of colorectal cancer.

    Abstract

    TMB and Inflammatory Gene Expression Associated with Clinical Outcomes Following Immunotherapy in Advanced Melanoma

    Researchers reported exploratory analyses of the associations of tumor mutational burden, a four gene inflammatory gene expression signature, and BRAF mutation status with tumor response, progression-free survival, and overall survival in patients with advanced melanoma treated as part of the CheckMate 066 and 067 Phase III clinical trials evaluating immuno-oncology therapies.

    Abstract

    NAD+ Supplement Potentiates Tumor-Killing Function by Rescuing Defective TUB-Mediated NAMPT Transcription in Tumor-Infiltrated T Cells

    By performing both whole-genome CRISPR and metabolic inhibitor screens, scientists identified that nicotinamide phosphoribosyltransferase (NAMPT) was required for T cell activation.

    p16INK4a Regulates Cellular Senescence in PD-1-Expressing Human T Cells

    Using various clinically and physiologically relevant systems, researchers showed that a prominent feature of PD-1-expressing exhausted T cells was the development of cellular senescence features both in vivo and ex vivo.

    Regulatory T Cells Enhance Th17 Migration in Psoriatic Arthritis Which Is Reversed by Anti-TNF

    Utilising an in vitro migration assay, regulatory T cells from patients with psoriatic arthritis treated with conventional therapy paradoxically boosted CCR6+ effector T cell migration towards CCL20.

    Dysregulation of lncRNAs in Autoimmune Neuropathies

    Investigators selected HULC, PVT1, MEG3, SPRY4-IT1, LINC-ROR and DSCAM-AS1 long non-coding RNAs to appraise their transcript levels in the circulation of chronic inflammatory demyelinating polyradiculoneuropathy and Guillain-Barré syndrome cases versus controls.

    Melatonin as an Immunomodulator in Children with Down Syndrome

    Scientists demonstrated that melatonin had several significant effects by reducing CD11b and TLR4 expression, attenuating TLR signaling, genes involved in the inflammasome and had the potential to reduce LPS-induced inflammatory responses.

    Abstract

    IFNγ Signaling Integrity in Colorectal Cancer Immunity and Immunotherapy

    Scientists summarize recent advances in the epigenetic, genetic, and functional integrity of the IFNγ signaling pathway in the colorectal cancer microenvironment and its immunological relevance in the therapeutic efficacy of and resistance to immune checkpoint blockade.
