    AutoCore: A Network-Based Definition of the Core Module of Human Autoimmunity and Autoinflammation

    Researchers used a network-based approach for integrating a set of 186 inborn errors of immunity with predominant autoimmunity/autoinflammation into a comprehensive map of human immune dysregulation, which they termed “AutoCore”.

    METTL3 Inhibition Induced by M2 Macrophage-Derived Extracellular Vesicles Drives Anti-PD-1 Therapy Resistance via M6A-CD70-Mediated Immune Suppression in Thyroid Cancer

    Scientists revealed that low METTL3 expression correlated with poor response to immune checkpoint blockade, and overexpressing METTL3 in tumor cells could enhance the efficacy of anti-PD-1 therapy in papillary thyroid cancer and anaplastic thyroid cancer.
