چکیده

Human interferon alpha 2a (hIFNα2a) is a cytokine regulating immune system that has been used in hepatitis and cancer treatments. It has wide biological potency covering antiviral, antiproliferative and immunomodulative activities. This mini review discusses Roferon-A as a prominent commercial product of recombinant hIFNα2a which is produced in bacterial system, Escherichia coli, as therapeutic protein for several diseases, such as chronic viral Hepatitis B, Hepatitis C, melanoma, hairy cell leukemia and renal cell carcinoma. The discussion focuses on the development process with regard to its manufacturing, preclinical and clinical studies, as well as therapeutic efficacy. In addition, we also discuss biosimilar development of hIFNα2a and its potential future developments in the context of enhancing pharmacokinetic profiles.

The Effect of Heat Shock on Production of Recombinant Human Interferon Alpha 2a (rhIFN α -2a) by Escherichia coli

Recombinant human interferon alpha 2a (rhIFN α -2a) production and cell growth were monitored in a set of genetically modified E. coli strains (MSD1519, MSD1520, MSD 1521, MSD 1522, MSD 1523) producing rhIFN α -2a. The growth was followed at OD 600 nm, changes in cell physiology were detected by pyrolysis mass spectrometry (PyMS) of cell biomass and recombinant protein production was determined...

In a randomised controlled trial recombinant interferon alpha 2A (Roferon-A, rIFN alfa A) given at a dosage of 10 million units (MU)/m2 thrice weekly for six months was significantly better (p less than 0.02) than no treatment in producing a sustained loss of hepatitis Be antigen (HBeAg) in hepatitis B virus (HBV) chronic carriers. Although lower doses (5 MU/m2 and 2.5 MU/m2) also produced some...

Augmentation of activity of cis-diamminedichloroplatinum(II) and mitomycin C by interferon in human malignant mesothelioma xenografts in nude mice.

Two human mesothelioma xenograft lines, BG and ES, serially passaged in athymic mice, were studied to determine the efficacy of alpha-interferon in this type of tumor. Treatment began after progressive tumor growth was established. Recombinant human alpha-interferon-2a (Roferon- A) was given by s.c. injection, at a site distant from the tumor, at a dose of 2 x 10(5) IU 5 days per wk for 5 wk. M...

Induction of antiviral factors by IFN-α 2a is time and dose dependent

Background and Aims: Interferon alpha is an effective cytokine in viral infections, where it has various roles in immune function. The use of this antiviral agent in the treatment of viral infections and even cancers is common, although, the beneficial effects of this antiviral agent in high doses can be associated with side effects that limit its use. In this project, we tried to investigate t...

Biologic activity in a fragment of recombinant human interferon alpha.

To attempt to locate functionally important regions of the interferon (IFN) molecule, recombinant human IFN-alpha 2 was subjected to proteolytic digestion. The bacterial proteinase thermolysin produced two major complementary fragments, HuIFN-alpha 2-(1-110) and HuIFN-alpha 2-(111-153). After reduction with 2-mercaptoethanol and separation of the two major fragments on NaDodSO4/polyacrylamide g...
