    Single-Cell RNA Sequencing Uncovers a Neuron-Like Macrophage Subset Associated with Cancer Pain

    By elucidating the transcriptome dynamics of tumor-associated macrophages with single-cell resolution, investigators discovered a phenomenon “macrophage to neuron-like cell transition” for directly promoting tumoral neurogenesis.

    TGF-β-Dependent Lymphoid Tissue Residency of Stem-Like T Cells Limits Response to Tumor Vaccine

    Researchers showed that in a mouse melanoma model, in the tumor-draining lymph nodes rather than in the tumors themselves, stem-like CD8+ T cells differentiate into TRMs in a TGF-β and tumor antigen dependent manner.

    Reprogramming of Myeloid Cells and Their Progenitors in Patients with Non-Medullary Thyroid Carcinoma

    Scientists showed single-cell transcriptomics and functional analyses of the myeloid cell lineage in patients with non-medullary thyroid carcinoma and multinodular goiter, before and after treatment with radioactive iodine compared to healthy controls.

    Abstract

    Colorectal Cancer Metastases in the Liver Establish Immunosuppressive Spatial Networking between Tumor Associated SPP1+ Macrophages and Fibroblasts

    Scientists identified tumor microenvironment-specific SPP1-expressing macrophages with altered metabolism features, foam cell characteristics and increased activity in extracellular matrix organization.

    Abstract

    Molecular Landscape of Immune Pressure and Escape in Aplastic Anemia

    Researchers studied the genetic and transcriptomic make-up of the antigen presentation complexes in a large cohort of patients with idiopathic aplastic anemia and paroxysmal nocturnal hemoglobinuria by using single-cell RNA, high throughput DNA sequencing and single nucleotide polymorphism-array platforms.

    Abstract

    Absence of Epstein-Barr Virus DNA in Anti-Citrullinated Protein Antibody-Expressing B Cells of Patients with Rheumatoid Arthritis

    Anti-citrullinated protein antibodies-expressing B cells derived from peripheral blood of seven Epstein-Barr virus (EBV)-seropositive rheumatoid arthritis (RA) patients, and synovial fluid of one additional EBV-seropositive RA patient, were isolated by flow cytometry.

    Abstract

    Generation of Murine Tumour-Reactive T Cells by Co-Culturing Murine Pancreatic Cancer Organoids and Peripheral Blood Lymphocytes

    15 hub genes were identified, among which inducible T cell co‑stimulator was indicated to serve a role in the most pivotal immunity pathways. pSS was markedly associated with inflammatory pathways.

    Allergen Immunotherapy: Past, Present and Future

    Research and clinical trials over the past few decades have elucidated the mechanisms underlying immunotherapy-induced tolerance, involving a reduction of allergen-specific T helper 2 cells, an induction of regulatory T and B cells, and production of IgG and IgA ‘blocking’ antibodies.
