The production of IL 1 by LPS-stimulated peritoneal macrophages from inbred mouse strains was studied. Macrophages from A/J (A) mice were deficient in IL 1 production, when compared with high IL 1-producing strains, including C57BL/6J (B). The difference between A and B macrophages was maintained over a wide LPS concentration range and throughout a 72-hr incubation period. Because of these differences, it was possible to investigate the mechanisms regulating IL 1 production by applying techniques of genetic analysis by using recombinant inbred (RI) strains derived from the A and B progenitors. A strain distribution pattern (SDP) of IL 1 production (low/high response) was obtained with the use of 15 AXB/BXA RI strains. This suggested the presence of a major gene locus controlling the production of IL 1 in response to LPS stimulation, with allelic differences presumably resulting in deficient or efficient IL 1 production. In addition, there appeared to be one or more other loci involved in determining the magnitude of the IL 1 response to LPS in the responder mice. The IL 1 response did not appear to be linked to the major histocompatibility complex, since B10.A mice (which share the same H-2a haplotype as A/J) were efficient IL 1 producers. There did not appear to be any correlation between the degree of IL 1 production and the magnitude of the peritoneal macrophage inflammatory response, or between IL 1 production and LPS responsiveness (as determined by splenocyte proliferation). SDP analysis also indicated that the IL 1 response was not linked to macrophage tumoricidal activity. A comparison of the SDP for IL 1 production with a library of SDP for other known genetic waits suggested linkage with at least four loci on chromosome 1.
