Abstract:
The present invention provides an inducible nitric oxide synthase ("iNOS")-deficient transgenic mouse, novel replacement vectors designed for the disruption of the iNOS gene, embryonic stem (ES) cells which are singly allelic relative to the deficient iNOS locus, a host cell line or cell clone carrying a congenitally altered iNOS gene, and a method of producing such a transgenic mouse. The iNOS-deficient transgenic mice can be used to evaluate and/or test their susceptibility to infectious or tumorigenic challenge, autoimmunity, septic shock and inflammatory and allergic diseases.
