Somatic cell genetic analysis of the interferon system.
Current advances in the use of somatic cell hybrid systems have enhanced the value of these systems for studying eukaryotic cell functions. We have reviewed the use of somatic cells to investigate the human interferon system. It has been shown that interspecific heterokaryons and hybrid cells can produce interferon(s) of both parental types and may be protected from viral challenge by interferon(s) from either parent. Using mouse-human hybrid cells we have assigned a human gene(s) responsible for regulating interferon to chromosome 21 and genes involved in the production of human interferon to chromosomes 2 and 5. Our data also suggest possible assignment of a locus involved in control of interferon production to chromosome 16. Suggested further uses of the somatic cell system for interferon studies include study of the subunit structure of interferons and the development of hybrid lines that produce human interferon at high levels (interferon/somatic cell hybrids/human gene assignment.
