Selection of a suitable assay to measure the activity of drug agents based on release-active forms of anti-interferon-gamma antibodies (RA forms of Abs) is an important step forward in the investigation of such agents. In this study, the enzyme-linked immunosorbent assay was utilized to examine the effect of RA forms of Abs specific for human interferon gamma on the interaction between monoclon...

OBJECTIVE The purpose of the present study was to determine whether type III IFN can modulate the autophagic response in human osteosarcoma cell. METHODS Human osteosarcoma cell were treated with Interferon-λ1. We investigated that Interferon-λ1 could inhibit the invasive ability of osteosarcoma cells by Matrigel invasion assay. Autophagy were assessed by acridine orange staining, MDC stainin...

Treatment of Daudi cells with successively increasing concentrations of interferon-alpha resulted in the selection of a cell population which multiplied in the continued presence of 10(4) units/ml of interferon-alpha. A number of clones of interferon-resistant Daudi cells were isolated from this population. Two clones, DIF2 and DIF3, were found to exhibit moderate and pronounced resistance, res...

Johnson, Terry C. (University of Minnesota, Minneapolis), and Leroy C. McLaren. Plaque development and induction of interferon synthesis by RMC poliovirus. J. Bacteriol. 90:565-570. 1965.-Plaque development by RMC poliovirus on human amnion cell monolayers was investigated with regard to autointerference and to the effect of acid-agar overlay on plaquing efficiency. The virus was inhibited by a...

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...

Henipaviruses encode several proteins from the P gene, of which V and W have been demonstrated by gene-based transfection studies to antagonize the innate immune response, blocking both type I interferon production and signaling. This study examines the effects of henipavirus infection on the innate immune response in human cell lines. We report that henipavirus infection does not result in int...

This report describes an accurate, reproducible, and efficient microassay for human interferon, using a dye-uptake method to quantitate cytopathogenicity. The antiviral activity was measured by using a Gilford 300-N microsepctrophotometer, with the automatic programmer, sampler, and data lister. Two hundred interferon samples, each in a final volume of 1.0 ml, may be analyzed and recorded in 45...
