title: Chemotaxis in yersinia arthritis. HLA-B27 positive neutrophils show high stimulated motility in vitro.
abstract: Chemotaxis, chemokinesis, and spontaneous locomotion of polymorphonuclear leukocytes (PMNs) of yersinia arthritis (YA) patients and healthy subjects with or without HLA-B27 were studied by agarose assay and membrane filter technique. HLA-B27 positive healthy control subjects and yersinia patients showed significantly higher response to chemotactic stimulus than HLA-B27 negative controls. Consequently, the high response was associated with HLA-B27 irrespective of YA. The high responder PMNs may contribute to the more severe inflammatory symptoms in YA patients with HLA-B27.
