    Follicular Lymphoma Triggers Phenotypic and Functional Remodeling of the Human Lymphoid Stromal Cell Landscape

    Investigators examined the effect of B cell stimuli on lymphoid stromal cells in follicular lymphoma (FL). FL B cells interacted primarily with CD49a+ fibroblastic reticular cells.

    Intratumoral Follicular Regulatory T Cells Curtail Anti-PD-1 Treatment Efficacy

    Scientists found that tumor-infiltrating follicular regulatory T cells were prevalent in tumor tissues of several cancer types.

    Abstract

    A Biliary Immune Landscape Map of Primary Sclerosing Cholangitis Reveals a Dominant Network of Neutrophils and Tissue-Resident T Cells

    By combining endoscopy-guided sampling of the biliary tree with a high-dimensional analysis approach, comprehensive mapping of the human biliary immunological landscape in patients with primary sclerosing cholangitis, a severe biliary inflammatory disease, was conducted.

    Abstract

    Molecular Determinants of Response to PD-L1 Blockade across Tumor Types

    Researchers complemented PD-L1 immunohistochemistry and tumor mutation burden with RNA-seq in 366 patients to identify unifying and indication-specific molecular profiles that could predict response to checkpoint blockade across tumor types.

    Inflammatory Cytokines TNFα and IL-17 Enhance the Efficacy of Cystic Fibrosis Transmembrane Conductance Regulator Modulators

    To learn whether inflammation alters cystic fibrosis (CF) airway surface liquid pH, researchers treated CF epithelia with TNFα and IL-17, two inflammatory cytokines that are elevated in CF airways.

    Conventional NK Cells and Tissue-Resident ILC1s Join Forces to Control Liver Metastasis

    Using different preclinical models for liver metastasis, researchers found that tissue-resident type I innate lymphoid cells controlled metastatic seeding, whereas conventional NKs restrained outgrowth.

    Abstract

    Very-Low-Carbohydrate Diet Enhances Human T-Cell Immunity through Immunometabolic Reprogramming

    Scientists investigated this topic in an in vitro model using primary human T cells and in an immuno-nutritional intervention study enrolling healthy volunteers.

    CD86+ Antigen-Presenting B Cells Are Increased in Cancer, Localize in Tertiary Lymphoid Structures, and Induce Specific T-Cell Responses

    Researchers used multicolor flow cytometry and immunohistochemistry to elucidate abundance and spatial distribution of antigen-presenting B cells in blood and tumor samples of 238 cancer patients.

    Abstract

    Activated T Cell-Derived Exosomal PD-1 Attenuates PD-L1-Induced Immune Dysfunction in Triple-Negative Breast Cancer

    Despite its well-documented inhibitory effects, higher PD-1 expression in tumor-infiltrating lymphocytes was significantly associated with longer survival in triple-negative breast cancer patients.

    High Th2 Cytokine Levels and Upper Airway Inflammation in Human Inherited T-Bet Deficiency

    The authors explored the persistent upper airway inflammation and blood eosinophilia of s patient. Unlike wild-type T-bet, the mutant form of T-bet from this patient did not inhibit the production of Th2 cytokines, including IL-4, IL-5, IL-9, and IL-13, when overexpressed in T helper 2 (Th2) cells.

    Abstract

    Low Number of KIR Ligands in Lymphoma Patients Favors a Good Rituximab-Dependent NK Cell Response

    Investigators deeply investigated the impact of KIR, HLA class I, and CD16 genotypes on rituximab-dependent NK cell responses in both an in vitro cellular model from healthy blood donors and ex vivo rituximab-treated non-Hodgkin lymphoma patients.
