Type I interferons (IFNs) are essential mediators of antiviral responses. These cytokines have been implicated in the pathogenesis of autoimmunity, most notably systemic lupus erythematosus (SLE), diabetes mellitus, and dermatomyositis, as well as monogenic type I interferonopathies. Despite a fundamental role in health and disease, the direct quantification of type I IFNs has been challenging. Using single-molecule array (Simoa) digital ELISA technology, we recorded attomolar concentrations of IFNα in healthy donors, viral infection, and complex and monogenic interferonopathies...

BACKGROUND: HBsAg clearance represents a clinical cure although the clearance rate is extremely low. The aim of this study was to evaluate the feasibility and safety profiles of pegylated-interferon α-2a (PEG-IFNα-2a) as a therapeutic option for inactive HBsAg carriers (IHCs). METHODS: 144 IHCs were enrolled and divided into a therapeutic group (102 subjects) and control group (42 subjects). PEG-IFNα-2a and PEG-IFNα-2a combined with Adefovir Dipivoxil (ADV) were used for treatment group subjects with hepatitis B virus (HBV) DNA <20 IU/mL and 20 IU/mL≤HBV DNA<2000 IU/mL, respectively...

BACKGROUND: Segmental duplications (SDs) commonly exist in plant and animal genomes, playing crucial roles in genomic rearrangement, gene innovation and the formation of copy number variants. However, they have received little attention in most livestock species. RESULTS: Aiming at characterizing SDs across the genomes of diverse livestock species, we mapped genome-wide SDs of horse, rabbit, goat, sheep and chicken, and also enhanced the existing SD maps of cattle and pig genomes based on the most updated genome assemblies...

Thanks to the use of targeted therapies, the prognosis of patients with metastatic renal cell carcinoma (mRCC) has improved significantly. A median overall survival of more than 2 years is a realistic claim. These improvements are also reflected in recent discussions about 3 and more lines of therapy.Sunitinib, pazopanib, the combination of bevacizumab and interferon alpha, and temsirolimus are approved for first-line therapy of mRCC. Sunitinib and pazopanib are also approved for second-line therapy, which, for pazopanib, is confined to the use after cytokine failure...

BACKGROUND: Plasmacytoid dendritic cells (pDC) are a subset of DC specialized in the production of type I interferon (IFN-α/β) and involved in various cutaneous inflammatory and autoimmune disorders, such as cutaneous lupus (CLE) and vitiligo. Heat-Shock proteins (HSP) are molecular chaperones essential for maintaining cellular functions, but can act as a danger signal during inflammation. OBJECTIVES: To decipher the role of HSP70 in the production of IFNα by pDC in CLE and vitiligo...

Ebola virus (EBOV) protein VP35 inhibits production of interferon alpha/beta (IFN) by blocking RIG-I-like receptor signaling pathways, thereby promoting virus replication and pathogenesis. A high-throughput screening assay, developed to identify compounds that either inhibit or bypass VP35 IFN-antagonist function, identified five DNA intercalators as reproducible hits from a library of bioactive compounds. Four, including doxorubicin and daunorubicin, are anthracycline antibiotics that inhibit topoisomerase II and are used clinically as chemotherapeutic drugs...

BACKGROUND: hepatitis E virus (HEV) infection is increasingly being reported in immunocompromised patients, and particularly organ transplant recipients. In this context, HEV infection frequently evolves to chronic infection with a rapid progression of fibrosis to cirrhosis. Ribavirin monotherapy and a minimisation of immunosuppression represent the treatment of choice, with a good response rate. However, no data are available on whether treatment can achieve a regression of liver fibrosis in chronic HEV patients...

OBJECTIVE: Interestingly, evidence is currently emerging that the activation of angiogenesis leads to immunomodulatory/immunosuppressive effects both at the local and systemic levels. These are very complex and interconnected processes. In this study, our aim was to establish interferon alpha-2b as an anti-angiogenic agent and show the complexity of angiogenesis and immunomodulation through the serum levels of vascular endothelial growth factor (VEGF) and matrix metalloproteinase 8 (MMP-8) in high-risk resected malignant melanoma before and after adjuvant therapy with high-dose interferon alpha-2b (HDI)...

Familial Mediterranean fever (FMF) is the most common hereditary auto-inflammatory (periodic fever) syndrome, and usually successfully treated with colchicine. However, nearly 5-10% of FMF cases are resistant or intolerant to colchicine and treatment options are highly restricted in these cases. Biologics including anakinra, canakinumab, rilonacept, etanercept, infliximab, interferon-alpha, and tocilizumab are shown to have efficacy to control FMF attacks. Tofacitinib, a Janus kinase (JAK) inhibitor, is an orally administered non-biologic disease modifying anti-rheumatic drug for the treatment of rheumatoid arthritis (RA)...

In our previous work, we found that the expression of ubiquitin-specific protease 18 (USP18), also known as UBP43, is associated with the efficiency of interferon alpha (IFN-α) treatment in patients with chronic hepatitis B (CHB). To elucidate the influence of USP18 on hepatitis B virus (HBV) replication and the mechanism of this activity, we silenced USP18 by introducing short hairpin RNA (shRNA) into Hepg2.2.15 cells. To identify the changed genes and pathways in Hepg2.2.15-shRNA-USP18 cells, we performed a microarray gene expression analysis to compare the Hepg2...

Hepatitis C virus (HCV) is widely used to investigate host-virus interactions. Cellular responses to HCV infection have been extensively studied in vitro However, in human liver, interferon (IFN)-stimulated gene expression can mask direct transcriptional responses to infection. To better characterize the direct effects of HCV infection in vivo, we analyze the transcriptomes of HCV-infected patients lacking an activated endogenous IFN system. We show that expression changes observed in these patients predominantly reflect immune cell infiltrates rather than cell-intrinsic pathways...

Adult T-Cell Leukemia/lymphoma (ATL) is the first human malignancy associated with a chronic infection by a retrovirus, the human T-cell lymphotropic virus type I (HTLV-I). ATL occurs, after a long latency period, only in about 5% of 10-20 millions infected individuals. ATL has a dismal prognosis with a median survival of less than 1 year, mainly due to its resistance to chemotherapy and to a profound immunosuppression. The viral oncoprotein, Tax, plays a major role in ATL oncogenic transformation by interfering with cell proliferation, cell cycle, apoptosis, and DNA repair...

Interferon alpha and its surrogates, including IP-10 and SIGLEC1, paralleled changes of disease activity in systemic lupus erythematosus (SLE). However, the whole blood interferon signature (WBIFNS)-the current standard for type I IFN assessment in SLE-does not correlate with SLE disease activity in individual patients over time. The underlying causes for this apparent contradiction have not been convincingly demonstrated. Using a multicenter dataset of gene expression data from leukocyte subsets in SLE, we identify distinctive subset-specific contributions to the WBIFNS...

BACKGROUND: T cells engineered to express chimeric antigen receptors (CARs) have established efficacy in the treatment of B-cell malignancies, but their relevance in solid tumors remains undefined. Here we report results of the first human trials of CAR-T cells in the treatment of solid tumors performed in the 1990s. METHODS: Patients with metastatic colorectal cancer (CRC) were treated in two phase 1 trials with first-generation retroviral transduced CAR-T cells targeting tumor-associated glycoprotein (TAG)-72 and including a CD3-zeta intracellular signaling domain (CART72 cells)...

REVIEW
Camille Mazza, Bernard Escudier, Laurence Albiges
Similar to melanoma, renal cell carcinoma (RCC) has been historically considered as an immunogenic tumor, with interleukin 2 (IL-2) and interferon alpha (IFN-α) being the first approved treatments in the 1990s. However, these therapies were effective in only 10-20% of cases and were not well tolerated. Recently, new insights on the interaction between the immune system and tumor have identified the programmed death-1/programmed death-ligand-1 (PD-1/PD-L1) pathway to be a key player in evading host immune responses...
