Abstract
- The paper reports the assessment of the role of surface antigens in Yersinia pestis adhesion to murine macrophages J774. The ability of Ail and Psa antigens to adhere to eukaryotic cells has been confirmed using optical trapping and/or passive adhesion methods. The YapF autotransporter was shown for the first time to be an adhesin of Y. pestis. It has been suggested that these antigens do not have complementary receptors on the macrophage surface and their adhesive properties are nonspecific. The results of studying passive adhesion of polystyrene microspheres sensitized with the F1 capsular antigen to J774 macrophages suggest that its inhibiting effect on the adhesion to macrophages is determined not only by spatial shielding of underlying adhesins by the capsule but also by physical and chemical properties of the antigen itself.
