    Characterization
    of Ascites- and Tumor-Infiltrating γδ T Cells Reveals Distinct Repertoires and a Beneficial Role in Ovarian Cancer

    The authors demonstrated that tumor-infiltrating γδ T cells isolated from patients with ovarian cancer have distinct T cell receptors and exhibit more innate-like functions compared to blood- or ascites-derived γδ T cells.

    Abstract

    Personalized Neoantigen Pulsed Dendritic Cell Vaccine for Advanced Lung Cancer

    Scientists attempted to treat lung cancer using a personalized neoantigen peptide-pulsed autologous dendritic cell vaccine and conducted a single-arm, two medical centers, pilot study initiated by the investigator.

    Abstract

    Nanoparticle T-Cell Engagers as a Modular Platform for Cancer Immunotherapy

    Investigators developed nanoparticle-based bispecific T-cell engagers, which were liposomes decorated with anti-CD3 monoclonal antibodies (mAbs) targeting T cells, and mAbs targeting the cancer antigen.

    T-ALL Can Evolve to Oncogene Independence

    Researchers found that the related transcription factor TAL1 was dispensable in several human T-cell acute lymphoblastic leukemia (T-ALL) cell lines that contained SIL-TAL1 chromosomal deletions driving its overexpression, indicating that evolution to oncogene independence could also occur in human T-ALL.

    Abstract

    Designed
    PKC-Targeting Bryostatin Analogs Modulate Innate Immunity and Neuroinflammation

    Scientists showed that multiple synthetically accessible bryologs replicated the anti-inflammatory effects of bryostatin-1 on innate immune cells in vitro, and a lead bryolog attenuates neuroinflammation in vivo.

    Abstract

    Phosphodiesterase
    4A Confers Resistance to PGE2-Mediated Suppression in CD25+/CD54+ NK Cells

    The authors investigated if the modulation of the cytokine environment in lung cancer with IL‐2 or IL‐15 rendered NK cells resistant to suppression by PGE2.

    Perfect Adaptation of CD8+
    T Cell Responses to Constant Antigen Input Over a Wide Range of Affinities Is Overcome by Costimulation

    Researchers observed that in vitro–expanded primary human T cells exhibited perfect adaptation with respect to cytokine production to constant antigen stimulation across a 100,000-fold variation in affinity with partial T cell receptors down-regulation.

    HSP GRP94 Interacts with Macrophage Intracellular Complement C3 and Impacts M2 Profile During ER Stress

    Scientists studied GRP94 in M1/LPS + IFNγ and M2/IL-4 primary macrophages derived from human monocytes, in basal and endoplasmic reticulum (ER) stress conditions induced by thapsigargin, an inducer of ER calcium depletion and tunicamycin, an inhibitor of N-glycosylation.
