    Axicabtagene Ciloleucel in Large B Cell Lymphoma Ineligible for Autologous Stem Cell Transplantation: The Phase II ALYCANTE Trial

    Investigators conducted a Phase II study, ALYCANTE, to assess the efficacy and safety of a single axi-cel infusion as a second-line therapy in patients with high-risk relapsed/refractory large B cell lymphoma deemed ineligible for autologous stem cell transplantation but eligible for CAR T cell therapy.

    In Situ PEGylation of CAR T Cells Alleviates Cytokine Release Syndrome and Neurotoxicity

    The authors showed that in situ conjugation of polyethylene glycol to the surface of CAR T cells (‘PEGylation’) created a polymeric spacer that blocks cell-to-cell interactions between CAR T cells, tumor cells and monocytes.

    Targeted Glycan Degradation Potentiates Cellular Immunotherapy for Solid Tumors

    The combination of cancer cell desialylation and induced pluripotent stem cell–derived chimeric antigen receptor–macrophage adoptive cellular therapy exerted a dramatic therapeutic effect on solid tumors and significantly prolonged the survival of tumor-bearing mice.

    In Vitro Vascular Differentiation System Efficiently Produces Natural Killer Cells for Cancer Immunotherapies

    Human pluripotent stem cells were differentiated into hematopoietic progenitor cells (HPCs) and Natural Killer cells using a novel organoid system. HPC engraftment potential was assessed using NSG mice.

    Small RNA Sequencing Analysis of Exosomes Derived from Umbilical Plasma in IUGR Lambs

    Researchers established a heat-stressed Hu sheep model during mid-late gestation and selected intrauterine growth retardation (IUGR) and normal lambs for analysis. Exosomes from umbilical plasma were separated and small RNA sequencing was used to identify differentially expressed miRNAs.
