Production of functional bovine IL-22 in a mammalian episomal expression system
Interleukin 22 is a member of the interleukin-10 superfamily of cytokines. This protein has a dual role as an inflammatory and anti-inflammatory molecule dependent on the context. IL-22 is produced mainly by immune cells and seems to have non-hematopoietic cells as its target. In this work, we report the production of bovine IL-22 for the first time in a semi-stable expression system in mammalian cells. We showed that this recombinant IL-22 possesses biological activity in bovine macrophages infected with Mycobacterium bovis and is easy to produce in large quantities.
Given its role in the defence against infections, the IL-22 produced in this work has potential applications in scientific research as well as in immunotherapy to treat diseases in cattle.
期刊介绍：
The journal reports basic, comparative and clinical immunology as they pertain to the animal species designated here: livestock, poultry, and fish species that are major food animals and companion animals such as cats, dogs, horses and camels, and wildlife species that act as reservoirs for food, companion or human infectious diseases, or as models for human disease.
Rodent models of infectious diseases that are of importance in the animal species indicated above,when the disease requires a level of containment that is not readily available for larger animal experimentation (ABSL3), will be considered. Papers on rabbits, lizards, guinea pigs, badgers, armadillos, elephants, antelope, and buffalo will be reviewed if the research advances our fundamental understanding of immunology, or if they act as a reservoir of infectious disease for the primary animal species designated above, or for humans. Manuscripts employing other species will be reviewed if justified as fitting into the categories above.
The following topics are appropriate: biology of cells and mechanisms of the immune system, immunochemistry, immunodeficiencies, immunodiagnosis, immunogenetics, immunopathology, immunology of infectious disease and tumors, immunoprophylaxis including vaccine development and delivery, immunological aspects of pregnancy including passive immunity, autoimmuity, neuroimmunology, and transplanatation immunology. Manuscripts that describe new genes and development of tools such as monoclonal antibodies are also of interest when part of a larger biological study. Studies employing extracts or constituents (plant extracts, feed additives or microbiome) must be sufficiently defined to be reproduced in other laboratories and also provide evidence for possible mechanisms and not simply show an effect on the immune system.
