    Abstract

    Bacterial Cytoplasmic Membranes Synergistically Enhance the Antitumor Activity of Autologous Cancer Vaccines

    To specifically trigger sufficient antitumor reactivity without notable adverse effects, scientists developed an antigen and adjuvant codelivery nanoparticle vaccine based on Escherichia coli cytoplasmic membranes and tumor cell membranes from resected autologous tumor tissue.

    Abstract

    Metabolic Screening of Cytotoxic T-Cell Effector Function Reveals the Role of CRAC Channels in Regulating Lethal Hit Delivery

    Investigators developed a microscopy-based, automated 3D interface coculture model suitable for medium-throughput screening to delineate the steps and cytotoxic T lymphocytes effector mechanisms affected by microenvironmental perturbation.

    Abstract

    An Immunogenomic Signature for Molecular Classification in Hepatocellular Carcinoma

    Gene set enrichment analysis was used to calculate scores of immune pathways for hepatocellular carcinoma, and hierarchical clustering in two databases. The scores of the immune microenvironment and the proportions of 22 immune cells were also calculated.

    Abstract

    Comprehensive Analysis of an Immune-Related ceRNA Network in Identifying a Novel lncRNA Signature as a Prognostic Biomarker for Hepatocellular Carcinoma

    A signature was constructed by 11 immune-related prognostic long non-coding (lnc)RNAs from the competitive endogenous (ce)RNA network. The survival analysis and receiver operating characteristic analysis validated the reliability of the signature.

    YIV-906 Potentiated Anti-PD1 Action against Hepatocellular Carcinoma by Enhancing Adaptive and Innate Immunity in the Tumor Microenvironment

    Researchers demonstrated that YIV-906 plus anti-PD1 could eradicate all Hepa 1–6 tumors in all tumor bearing mice. YIV-906 was found to have multiple mechanisms of action to enhance adaptive and innate immunity.

    Similarities and Differences between IL11 and IL11RA1 Knockout Mice for Lung Fibro-Inflammation, Fertility and Craniosynostosis

    Scientists generated IL11 knockout (Il11−/−) mice that were born in expected ratios and have normal hematological profiles. Lung fibroblasts from Il11−/− mice were resistant to pro-fibrotic stimulation with TGFβ1.

    Intrinsic and Extrinsic Regulation of IgE B Cell Responses

    Although IgE responses are normally constrained, recent studies suggest that specific conditions can induce the formation of IgE responses with enhanced affinity or longevity, effectively ‘breaking the rules’ of IgE regulation.

    Australia’s Top Supplier of Lab Mice and Rats to Shut Down Operations

    Australia’s leading breeder and supplier of lab mice and rats is preparing to close its doors, leaving researchers scrambling for alternatives. The closure “would have major implications for Australia’s medical research effort,” says Malcolm France, a Sydney-based veterinarian who advises institutions on the care and management of animals used in research.
