background: hepatitis c is a global health problem. the exact mechanisms by which hepatitis c virus (hcv) can evade the host immune system have become controversial. whether hcv polyproteins modulate ifn signalling pathways or hcv proteins are responsible for such a property is the subject of interest. therefore, an efficient baculovirus delivery system was developed to introduce the whole geno...
background: dendritic cells (dc) are a key regulator of the immune response, and interferon- beta (ifn-β) is considered an immunomodulatory molecule for dc. objective: the purpose of this study was to evaluate the ability of ifn-β treated dc to induce cytokine secretion by cd4+ t cells. methods: dendritic cells were generated from blood monocytes with granulocyte-monocyte colony-stimulating fac...
conclusions lrrfip1 and its mediated production of type i interferon play a role in controlling hcv infection. the findings of this study provide new target for hcv treatment and contribute to development of anti-hcv drugs. results lrrfip1 increased the expression of ifn-β in hepatocytes with or without hcv infection. induction of ifn-β by lrrfip1 was enhanced with the presence of hepatitis c v...
Glioblastoma is the most common malignant brain tumor in adults and characterized by a poor prognosis. Glioma cells expressing O(6)-methylguanine DNA methyltransferase (MGMT) exhibit a higher level of resistance toward alkylating agents, including the standard of care chemotherapeutic agent temozolomide. Here, we demonstrate that long-term glioma cell lines (LTL) as well as glioma-initiating ce...
The ability of IFN-β to induce IL-10 production from innate immune cells is important for its anti-inflammatory properties and is believed to contribute to its therapeutic value in treating multiple sclerosis patients. In this study, we identified that IFN-β stimulates IL-10 production by activating the JAK1- and PI3K-signaling pathways. JAK1 activity was required for IFN-β to activate PI3K and...
Davoudi-Monfared et al. (1) report in this journal the results from a clinical trial on coronavirus disease 2019 (COVID-19) patients showing that subcutaneous administration of interferon beta (IFN-β) was associated with more rapid recovery severe acute respiratory syndrome 2 (SARS-CoV-2) infection and decreased mortality. These findings have been corroborated by two recent phase trials during ...
BACKGROUND Interferon-β (IFN-β) is an effective drug in multiple sclerosis (MS) but it may cause acute exacerbation of MS following the initiation of treatment. This study evaluated patients with rapid exacerbation of multiple sclerosis (REMS) following the initiation of IFN-β. METHODS We retrospectively reviewed the clinical records of 2350 patients with multiple sclerosis who started treatm...
INTRODUCTION Type 1 interferon is in widespread use as adjuvant therapy to inhibit melanoma progression. Considering the tumor-suppressive effects of local administration of interferon-β (IFN-β) on lymphatic metastasis, the present study was conducted to identify melanoma-suppressive molecules that are up-regulated by IFN-β treatment of lymphatic endothelial cells. MATERIALS AND METHODS Lymph...
Human interferons (IFNs) are key cytokines secreted by immune system. They have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. The type IFNs present in humans are α, β and Υ. IFN β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than IFN . Structural properties of I FNs are importan...
