Ly49Q defines 2 pDC subsets in mice.
Plasmacytoid dendritic cells (pDCs) play an important primary role for antiviral innate immunity by rapidly producing large amounts of type 1 interferon (IFN) upon viral infection. To study pDC biology, we generated a monoclonal antibody, termed 2E6, that recognizes pDCs. Molecular cloning of a cDNA encoding the 2E6 antigen revealed that it is a type II C-type lectin, Ly49Q, that consists of 24...
متن کاملType I interferon regulates respiratory virus infected dendritic cell maturation and cytokine production.
Activation of dendritic cells (DCs) by viruses is critical for both innate and adaptive immune responses. In this report, we investigated the role of type I interferon (IFN) in the activation of DCs by respiratory syncytial virus (RSV). Using DCs from type I IFNR-/- mice, these studies indicate that maturation, including upregulation of co-stimulatory molecules and optimal cytokine production, ...
متن کاملGlatiramer acetate treatment negatively regulates type I interferon signaling
OBJECTIVE Glatiramer acetate (GA; Copaxone), a disease-modifying therapy for multiple sclerosis (MS), promotes development of anti-inflammatory (M2, type II) monocytes that can direct differentiation of regulatory T cells. We investigated the innate immune signaling pathways that participate in GA-mediated M2 monocyte polarization. METHODS Monocytes were isolated from myeloid differentiation ...
متن کاملKAP1 regulates type I interferon/STAT1-mediated IRF-1 gene expression.
Signal transducers and activators of transcription (STATs) mediate cell proliferation, differentiation, and survival in immune responses, hematopoiesis, neurogenesis, and other biological processes. Recently, we showed that KAP1 is a novel STAT-binding partner that regulates STAT3-mediated transactivation. KAP1 is a universal co-repressor protein for the KRAB zinc finger protein superfamily of ...
متن کاملType I Interferon Regulates the Expression of Long Non-Coding RNAs
Interferons (IFNs) are key players in the antiviral response. IFN sensing by the cell activates transcription of IFN-stimulated genes (ISGs) able to induce an antiviral state by affecting viral replication and release. IFN also induces the expression of ISGs that function as negative regulators to limit the strength and duration of IFN response. The ISGs identified so far belong to coding genes...
