AB  - In addition to being the main cause of mortality worldwide, bacterial and viral infections can be the cause of autoimmune and pregnancy disorders as well. The production of autoantibodies during infection can be explained by various mechanisms, including molecular mimicry, bystander cell activation and epitope spreading. Conversely, bacterial and viral infections during pregnancy are especially dangerous for the fetus. It is documented that infection-induced inflammatory processes mediated by Toll-like receptors (TLR) represent the main cause of preterm labour. We used two crucial bacterial components and TLR ligands, namely peptidoglycan and lipopolysaccharide, to stimulate BALB/c mice before immunisation with tetanus toxoid. Tetanus toxoid is an inactive form of the toxin produced by bacterium Clostridium tetani and shares structural similarity with plasma protein beta(2)-glycoprotein I. Treatment with peptidoglycan and lipopolysaccharide in combination with tetanus toxoid induced the production of pathological autoantibodies, different fluctuations in natural autoantibodies and different types of reproductive pathology in treated animals, with peptidoglycan treatment being more deleterious. We propose that the production of pathological autoantibodies, TLR activation and changes in natural autoantibodies play crucial roles in infection-induced reproductive pathology in our animal model.

AB  - One of the established animal models for autoimmune disease antiphospholipid syndrome (APS) is TTd hyperimmunization of mice. Tetanus toxoid (TTd) and plasma protein beta(2)GPI share structural homology so that immunization with TTd induces appearance of cross-reactive antibodies. In this paper, we have investigated the presence and dynamic of fluctuation of specific (anti-TTd) and auto (anti-beta(2)GPI) antibodies induced in BALB/c mice during secondary immune response after TTd immunization with alhydrogel or glycerol as adjuvants. In addition, we followed the induced reproductive pathology as a sign of autoimmune outcome. We show undoubtedly adjuvant dependance of (1) level of induced anti-TTd IgG antibodies, (2) changes in levels of low-affinity anti-beta(2)GPI IgG antibodies, and (3) change in fecundity and fertility during secondary immune response. These findings once more indicate the importance of chosen adjuvants used for successful immunization and eventual autoantibody outcome, this time associated with the processes involving low affinity, natural antibodies.
