Аннотация: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.
