HLA-B27 as a relative risk factor in ankylosing enthesopathy in transgenic mice
article
HLA-B27 is a risk factor for several human diseases through a mechanism that is not yet understood. This article describes a naturally occurring joint disease in laboratory mice, ANKENT. ANKENT begins with mild inflammation and culminates in irreversible stiffening of the ankle and/or tarsal joints in one or both hind paws. The macroscopic and histologic features of ANKENT, its relationship to age, gender, and environment, and some immunologic aspects are considered. With respect to genetics, it is demonstrated that an HLA-B27 transgene is a relative risk factor for ANKENT. Its impact depends on the H-2 haplotype, reaching a relative risk value of 9.4 for C57B1/10, H-2b males (p < 0.025). Several features of ANKENT are reminiscent of human AS: joint pathology, age and gender distribution, the presence of non-MHC as well as MHC risk factors (including HLA-B27), and the suspicion that environmental factors are involved.
