AB  - Natural, polyreactive, low-affinity antibodies are known to play an important role not only
in the immediate defense against pathogens, but also in shaping the acquired immune response.
On the other hand, antigen specific, high-affinity antibodies can affect the balance of natural
antibodies and lead to autoimmune diseases. In this study we have analyzed the changes that occur
in the IgM and IgG pool of natural antibodies after immunization with split or whole virion
influenza vaccine. For this purpose, “in-house” developed ELISAs were used. The subjects were
divided, according to the vaccination status, into those who had been immunized with the
influenza vaccine in previous years and those who had been immunized for the first time. The
analysis indicated that the pool of natural antibodies was not impaired by the immunization,
evidenced by the lack of changes in any of the groups, and that certain fluctuations were induced
in order to maintain the homeostasis of the immune system.

AB  - Testing of every new vaccine involves investigation of its immunogenicity, which is based on monitoring its ability to induce specific antibodies in animals. The fastest and most sensitive method used for this purpose is enzyme-linked immunosorbent assay (ELISA). However, commercial ELISA kits with whole influenza virus antigens are not available on the market, and it is therefore essential to establish an adequate assay for testing influenza virus-specific antibodies. We developed ELISA with whole influenza virus strains for the season 2011/2012 as antigens and validated it by checking its specificity, accuracy, linearity, range, precision, and sensitivity. The results show that we developed high-quality ELISA that can be used to test immunogenicity of newly produced seasonal or pandemic vaccines in mice. The pre-existence of validated ELISA enables shortening the time from the process of vaccine production to its use in patients, which is particularly important in the case of a pandemic.

AB  - Recent data concerning antiphospholipid syndrome (APS) induction have shown that beta(2)-glycoprotein I (beta(2)GPI) binds lipopolysaccharide (LPS), which results in conformational changes, exposition of a cryptic epitope and possible pathological anti-beta(2)GPI antibody production. In order to investigate the effects of LPS on the induction of APS-related pathology, we performed hyperimmunization of BALB/c and C57BL/6 mice with LPS, alone or in combination with tetanus toxoid (TTd), a protein structurally similar to beta(2)GPI. We report that, although high affinity pathological anti-beta(2)GPI antibodies were produced in all groups of animals, the reproductive pathology was recorded only in mice that received both LPS and TTd, implying on the important roles of both infections and molecular mimicry in APS pathogenesis. Moreover, APS-related reproductive pathology was more pronounced in BALB/c (lowered fertility and fecundity) than C57BL/6 mice (lowered fecundity), which correlated well with the disruption in natural antibody network observed in BALB/c mouse strain.

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.
