Application

Interferon-αA human has been used to:
  • study the effect of Chikungunya virus on interferon-mediated JAK (Janus kinase)-STAT (signal transducers and activators of transcription) signaling
  • study the effect of interferon-α and PRK2 (protein kinase C-related kinase 2) inhibitors on hepatitis C virus replication
  • compare the effect of Monascus pigment derivatives on hepatitis C virus replication

Actions biochimiques/physiologiques

Cytokine with anti-viral, anti-proliferative, immunoregulatory, and proinflammatory activities. Type I Interferons are a closely related family of 165-172 amino acid proteins that are produced by leukocytes (α subtypes), fibroblasts (β subtypes), lymphocytes (ω subtypes) and ruminant embryos (τ subtypes). Interferon induces a variety of effects on target cells including antiviral, antiproliferative and immunomodulatory activities.

Forme physique

Supplied as a solution in 5 mM sodium acetate, pH 4.0.

Remarque sur l'analyse

The biological activity is determined in the cytopathic effect inhibition assay using MDBK cells with vesicular stomatitis virus (VSV). A cytopathic effect of 50% is produced with 1 unit/ml interferon. The units are determined with respect to WHO International standard reference for human interferonαA.

Chikungunya virus (CHIKV) is an emerging human pathogen transmitted by mosquitoes. Like that of other alphaviruses, CHIKV replication causes general host shutoff, leading to severe cytopathicity in mammalian cells, and inhibits the ability of infected cells to respond to interferon

Hepatitis C virus (HCV) infection causes chronic liver disease and is a major public health problem worldwide. The aim of this study was to evaluate the potential of Monascus pigment derivatives, which were derived from a microbial secondary metabolite synthesized

Hepatitis C virus (HCV) infection is a serious threat to human health worldwide. In spite of the continued search for specific and effective anti-HCV therapies, the rapid emergence of drug-resistance variants has been hampering the development of anti-HCV drugs designed

A convenient assay for interferons based on reduction of cytopathic effect was developed. The number of manipulations and the lengths of the various incubation steps were reduced to a minimum. The assay is simple to perform and can be completed

Altered epidermal differentiation along with increased keratinocyte proliferation is a characteristic feature of psoriasis and pityriasis rubra pilaris (PRP). However, despite this large degree of overlapping clinical and histologic features, the molecular signatures these skin disorders share are unknown. Using
