## Objective: Mice deficient in beta2-microglobulin (beta2m), but expressing the human major histocompatibility complex (mhc) class i molecule hla-b27, have been reported to develop spontaneous inflammatory arthritis (sa). we sought to determine whether, under certain conditions, beta2m deficiency alone was sufficient to cause sa, and if this might be a result of class i deficiency. ## Methods: The following types of mice were produced: mice of the mhc b haplotype genetically deficient in beta2m (beta2m(0)) on several genetic backgrounds (c57bl/6j [b6], balb/cj, sjl/j, mrl/mpj, and b6,129), mice deficient in the transporter associated with antigen processing (tap1(0)) on a b6,129 background, and hla-b27-transgenic beta2m(0) mice on a b6 background. cohorts were transferred from specific pathogen-free (spf) to conventional (non-spf) animal rooms, and evaluated clinically and histologically for the development of sa. ## Results: Sa occurred in tap1(0) and beta2m(0)/class i-deficient mice with a mixed b6,129 genome at a frequency of 30-50%, while 10-15% of b6, sjl/j, and balb/cj beta2m(0) mice developed this arthropathy. mrl/ mpj beta2m(0) mice were unaffected. expression of b27 did n
