Interferon-α Abrogates Tolerance Induction by Human Tolerogenic Dendritic Cells
BACKGROUND Administration of interferon-α (IFN-α) represents an approved adjuvant therapy as reported for malignancies like melanoma and several viral infections. In malignant diseases, tolerance processes are critically involved in tumor progression. In this study, the effect of IFN-α on tolerance induction by human tolerogenic dendritic cells (DC) was analyzed. We focussed on tolerogenic IL-1...
متن کاملRegulation of type I interferon responses by mitochondria-derived reactive oxygen species in plasmacytoid dendritic cells
Mitochondrial reactive oxygen species (mtROS) generated continuously under physiological conditions have recently emerged as critical players in the regulation of immune signaling pathways. In this study we have investigated the regulation of antiviral signaling by increased mtROS production in plasmacytoid dendritic cells (pDCs), which, as major producers of type I interferons (IFN), are the k...
متن کاملPlasmacytoid dendritic cells in angiolymphoid hyperplasia with eosinophilia
Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is characterized by irregularly-shaped blood vessels with an inflammatory infiltrate. While absent from normal skin, plasmacytoid dendritic cells (pDCs) infiltrate the skin upon injury and during several infectious, inflammatory, and neoplastic entities. In addition to providing anti-viral resistance, pDCs link the innate and adapti...
متن کاملInterferon-λs and Plasmacytoid Dendritic Cells: A Close Relationship
Interferon lambdas (IFNλs) are recently discovered cytokines acting not only at the first line of defense against viral infections but also at the mucosal barriers. In fact, a peculiar feature of the IFNλ system is the restricted expression of the functional IFNλR, which is known to be limited to epithelial cells and discrete leukocyte subsets, including the plasmacytoid dendritic cells (pDCs)....
متن کاملPlasmacytoid predendritic cells initiate psoriasis through interferon-α production
Psoriasis is one of the most common T cell-mediated autoimmune diseases in humans. Although a role for the innate immune system in driving the autoimmune T cell cascade has been proposed, its nature remains elusive. We show that plasmacytoid predendritic cells (PDCs), the natural interferon (IFN)-alpha-producing cells, infiltrate the skin of psoriatic patients and become activated to produce IF...
