Overview of Interferons and their Biotechnology

Type I interferons have antiviral and anti-proliferative effects on various cell types, including some tumor cells.
Type I interferons can increase natural killer (NK) and T-cytotoxic cell activity, leading to anti-tumor effects.
Different types of type I interferons have different antiviral to anti-proliferative activity ratios.
Type II interferon, IFN-γ, has weak antiviral and anti-proliferative activity but can potentiate the effects of type I interferons when co-administered.
IFN-γ promotes activation, growth, and differentiation of immune and inflammatory response cells, particularly macrophages.
Interferons were initially identified as potential therapeutics in the late 1950s but were impractical to use due to low levels in the body and species preference.
The Namalwa cell line became the primary source of interferons for industrial production.
Interferons were produced in significant quantities by mammalian cell culture in the late 1970s.
Recombinant DNA technology enabled the production of large quantities of pure interferon containing a single subtype.
Most interferons currently in medical use are recombinant human products produced by E. coli.
Clinical studies have shown that interferons can induce regression of tumors in patients with breast cancer, lymphomas, and multiple myeloma.
Recombinant interferons have been approved for the treatment of various cancer types, with up to 90% of patients experiencing significant regression of the cancer.
