    A Non-Antibiotic-Disrupted Gut Microbiome Is Associated with Clinical Responses to CD19-CAR-T Cell Cancer Immunotherapy

    The authors demonstrated that wide-spectrum antibiotics treatment prior to CD19-targeted CAR-T cell therapy was associated with adverse outcomes, but this effect was likely to be confounded by an increased pretreatment tumor burden and systemic inflammation in patients pretreated with such antibiotics.

    Neoantigen-Targeted CD8+ T Cell Responses with PD-1 Blockade Therapy

    Investigators captured neoantigen-specific T cells from blood and tumors from patients with metastatic melanoma, with or without response to PD-1 immunotherapy, and then generated personalized libraries of neoantigen–HLA capture reagents to single-cell isolate the T cells and clone their T cell receptors.

    The Pre-Existing T Cell Landscape Determines the Response to Bispecific T Cell Engagers in Multiple Myeloma Patients

    Researchers identified conserved behaviors of bone marrow-residing T cells in multiple myeloma patients undergoing BCMAxCD3 bispecific T cell engagers therapy.

    Linoleic Acid Potentiates CD8+ T Cell Metabolic Fitness and Antitumor Immunity

    The authors showed that linoleic acid was a major positive regulator of CD8+ T cell activity by improving metabolic fitness, preventing exhaustion, and stimulating a memory-like phenotype with superior effector functions.

    Immature Natural Killer Cells Promote Progression of Triple-Negative Breast Cancer

    Tumor samples from patients with triple-negative breast cancer (TNBC) and non-TNBC revealed that increased numbers of CD56bright NK cells were present in TNBC tumors, and were correlated to poor overall survival in patients with TNBC.

    Abstract

    Human Germline Heterozygous Gain-of-Function STAT6 Variants Cause Severe Allergic Disease

    Scientists identified 16 patients from 10 families spanning three continents with a profound phenotype of early-life onset allergic immune dysregulation, including hypereosinophilia with esosinophilic gastrointestinal disease, asthma, elevated serum IgE, IgE-mediated food allergies, anaphylaxis, and other manifestations.

    Accumulation of Branched-Chain Amino Acids Reprograms Glucose Metabolism in CD8+ T Cells with Enhanced Effector Function and Anti-Tumor Response

    Branched-chain amino acid (BCAA) supplementation recapitulated CD8+ T cell hyper-functions and synergized with anti-PD-1, in line with a better prognosis in non-small cell lung cancer patients containing high BCAAs when receiving anti-PD-1 therapy.

    Remibrutinib Inhibits Hives Effector Cells Stimulated by Serum from Chronic Urticaria Patients Independently of FcεR1 Expression Level and Omalizumab Clinical Response

    Scientists investigated the effects of the Bruton’s tyrosine kinase inhibitor, remibrutinib, on human blood basophils and CD34+-derived mast cells activation induced by serum obtained from chronic urticaria patients.
