Oncolytic viruses are complex biological agents that interact at multiple levels with both tumour and normal tissues. Antiviral pathways induced by interferon are known to have a critical role in determining tumour cell sensitivity and normal cell resistance to infection with oncolytic viruses. Here we pursue a synthetic biology approach to identify methods that enhance antitumour activity of o...

OBJECTIVE To determine the association of interferon alpha receptor-1 with success rate of interferon therapy in patients co-infected with hepatitis C virus and hepatitis B virus. METHODS The study was conducted at the Army Medical College, Rawalpindi, Pakistan, from December 2013 to November 2014, and comprised patients with hepatitis C and hepatitis B co-infection. The patients were treated...

conclusions compared with monotherapy, adding ribavirin to treatment is more effective in removing hepatitis c virus from the bloodstream in patients with thalassemia, it is also more effective in reducing the relapse rate after treatment. except the increase in blood transfusion, there was no significant increase in side effects followed by adding ribavirin. results three randomized clinical t...

Two murine models, C3H 38C13 B-cell lymphoma and AKR SL2 I cell lymphoma were used to determine the efficacy of three different Interferon preparations, recombinant human hybrid interferon-a A/D, recombinant murine Interferon (rMIFN)-7, and natural MIFN-a//3 (>85% ß), alone and in combination with tumor specific and nonspecific monoclonal antibody therapy. All three Interferon preparations hav...

OBJECTIVE Distribution of the type I interferon in different organs of the chicken digestive system. MATERIAL AND METHODS In order to obtain a certain length (274 bp) of a fragment, a pair of primers was designed according to the conserved nucleotide sequence of gallus IFNAR-1 (EU477527.1) fragment that was published by the GenBank. The fragment was cloned by pEASY-T1 and amplified by relativ...

Activated T cells synthesize and express a cell membrane-bound receptor for interleukin-2 (IL-2) and have recently been shown to secrete a soluble form of the same receptor. Hairy cell leukemia is a chronic disorder caused by expansion of a clonal population of an unusual mononuclear cell of B cell origin. These cells have previously been shown to express an IL-2 receptor on the cell membrane. ...

Natural killer cell activity, which represents the spontaneous cytotoxicity of lymphocytes toward tumor cells, has been measured in 173 tumor-bearing patients and 25 healthy volunteers; no significant difference was found in mean natural killer cell activity between the two groups. The parameters of interferon-induced activation of natural killer cells were studied in order to provide a suitabl...

Labial biopsy specimens from eight patients with primary Sjögren's syndrome (SS), 10 patients with secondary SS, and three healthy controls were studied with monoclonal antibodies identifying HLA class I and class II antigens; interferon-alpha, beta, and gamma; interleukin 2 (IL2); and the IL2 receptor (Tac) among others. In the normal biopsy specimens there was evidence of HLA class I and, to ...

Substantial increases in the concentrations of the excitotoxin and N-methyl-D-aspartate-receptor agonist quinolinic acid (QUIN) occur in human patients and non-human primates with inflammatory diseases. Such increases were postulated to be secondary to induction of indoleamine 2,3-dioxygenase in inflammatory cells, particularly macrophages, by interferon-gamma. To test this hypothesis, human pe...
