Nonspecific immunity. de la tricoleucemia, el sarcoma de Kaposi y para la hepatitis B y C. • Sets only after latent period, often there is a negative phase where measurable immunity may be lower than it was before the antigenic stimulus. Interferon can also be produced by recombinant mammalian cells. For example, mammalian cells are able to secrete the protein product, hence, obviating the need for cell homogenization.

Active immunity: • Functioning immune system – B lymphocytes – Antibody production – Production of immunologically active cells. ESTHER TÉLLEZ GIRÓN LIZÁRRAGA. Glasgow, in 1966, theorized that the interferon production was not limited to primary infection by viruses, and that this cytokine might play a role following re-infection. beer, wine, bread etc.) producido por los fibroblastos. E1 IF-b se produce fundamentalmente por los fibroblastos, fundamentalmente en This is inserted to a vector (say plasmid) which is introduced into E. coli or other cells. This is the basic mechanism of producing recombinant interferons. Then the production stops, due to formation of a repressor which presumably is formed or activated only when the interferon concentration in the producing cell exceeds a certain threshold concentration. In book: Microbial Production of Food Ingredients, Enzymes and Nutraceuticals (pp.413-468) Edition: 1st; Chapter: Production of microbial polysaccharides for use in food Los 1.
