Аннотация
In vivo experiments showed that antibodies to OmpC and OmpF porins of Yersinia pseudotuberculosis increased thyroxine (T4) level in the blood of experimental animals. The mice were immunized with different antigens: recombinant OmpF porin in a soluble monomeric form, trimers of OmpC and OmpF porins isolated from the outer membrane, or antibodies to them. The level of thyroxine in the blood of mice immunized with OmpF and OmpC porins increased by 5.47 and 22.3 times, respectively; after immunization with antibodies to these proteins, blood thyroxine increased by 9.28 and 14.29 times. Immunization with recombinant OmpF porin induced no reliable increase in thyroxine level. Hence, the serum to recombinant OmpF porin contains no antibodies specific to conformational antigenic determinants that are present in the protein trimer and, according to our previous findings from molecular docking studies, determine cross-reactions between OmpF porin of Y. pseudotuberculosis and thyroidstimulating hormone receptor.
