    Zyxin stabilizes RIG-I and MAVS interactions and promotes type I interferon response

    RIG-I and MDA5 are cytoplasmic viral RNA sensors that belong to the RIG-I-like receptors (RLRs), which induce antiviral innate immune responses, including the production of type I interferon and other pro-infl...

    Double-stranded RNA promotes CTL-independent tumor cytolysis mediated by CD11b+Ly6G+ intratumor myeloid cells through the TICAM-1 signaling pathway

    PolyI:C, a synthetic double-stranded RNA analog, acts as an immune-enhancing adjuvant that regresses tumors in cytotoxic T lymphocyte (CTL)-dependent and CTL-independent manner, the latter of which remains lar...

    Tumoricidal efficacy coincides with CD11c up-regulation in antigen-specific CD8+ T cells during vaccine immunotherapy

    Dendritic cells (DCs) mount tumor-associated antigens (TAAs), and the double-stranded RNA adjuvant Poly(I:C) stimulates Toll-like receptor 3 (TLR3) signal in DC, which in turn induces type I interferon (IFN) a...

    Aberrant PD-L1 expression through 3′-UTR disruption in multiple cancers

    Structural variations disrupting the 3′ region of PD-L1 are shown to aid immune evasion in a number of human cancers, including adult T-cell leukaemia/lymphoma, and in a mouse tumour model, CRISPR/Cas9-mediated d...

    Double-stranded RNA analog and type I interferon regulate expression of Trem paired receptors in murine myeloid cells

    Triggering receptors expressed on myeloid cells (Trem) proteins are a family of cell surface receptors used to control innate immune responses such as proinflammatory cytokine production in mice. Trem genes be...

    Pattern Recognition by Dendritic Cells and Its Application to Vaccine Adjuvant for Antitumor Immunotherapy

    Dendritic cells (DCs) initiate the maturation to a specific stage in response to stimuli with microbial pattern molecules (PAMP) and trigger activation of host immune response together with antigens (Ags). Rec...
